In the world of tools a saw that can sit on a workbench and has a handle to pull down for cutting, doesn’t make it a universal saw type. Did you know that chop saw and miter saw are not synonymous? That’s right! Each fills their own industry needs and cuts very different materials.
The Chop Saw
This tool, also known as a cut-off saw, was designed specifically for cutting metal. During its days of origin, professionals didn’t have much faith in a saw’s ability to cut through metal, but with a specific rotational speed and a uniquely designed blade, eventually, the chop saw became a metal industry standard for cutting. The chop saw is designed to cut straight lines and only moves up and down from its fixed position on the saw stand. When looking to cut at an angle, the fence that is fixed to the saw’s base is turned to determine the angle of the cut.
The Miter Saw
A miter saw, found often in woodworking is quite a versatile tool. Much like the name implies, this type of saw can create a miter – in many cases, these saws are dual bevel compound miter saws, which allows them to make many different adjustments to create combination cuts to the material. For example, you can tilt the saw leaning it both left and right creating an angled cut to the cut profile. You can also turn the saw, rotating it left or right away from the 90-degree starting point creating different cutting angles. And when you make adjustments to both the tilt and the rotation of the saw you are able to make a compound cut that is angled in multiple directions.
Though this type of saw is often found in woodworking, the ability to change the blade makes it useful for other materials as well. You can cut things like foam board, PVC, and even non-ferrous metals.
Both the miter saw and the chop saw have a similar design, in their abilities to be lowered to the material being cut, which allows the user a great amount of control. They both also allow for angled cuts, though the setup for creating an angle is done differently with each saw. Each saw serves a great purpose in their intended industry and though you may see both in a workshop, they will each have their own job to do.
Now, what was the difference between those other things?
Properly maintained equipment is important to your business’s operations and the safety of your employees. While your Minnich concrete equipment is built to handle tough and demanding tasks, it still requires attention on a regular basis.
As we grind through the hot summer months, one of the most important things you can do is prepare your concrete dowel pin drills and vibes for next season. Prioritizing equipment maintenance helps to ensure safe and trouble-free operation and can prevent larger repair costs in the future. Keep your equipment in top form with these tips:
PERFORM REGULAR MAINTENANCE
Performing regular maintenance to your concrete drill and vibe will help to minimize repairs, reduce downtime, and help lengthen equipment life.
To maximize operating efficiency, be sure to check the following during maintenance:
- Check the drill oil level. Just like your automobile, proper lubrication is vital to prolonging the life of your hammer drill. Knowing which type of lubrication and how much to use is essential to maximizing performance. There are two ways to check for proper lubrication:
- Rub your finger inside the exhaust deflector of the hammer drill. You should feel a fine oily film.
- There should also be evidence of oil around the collar of the drill steel. Oil shouldn’t be covering these areas, only the fine oily film should be evident.
Minnich dowel drills have adjustment screws to regulate the flow. Please reference your drill product page on our website to watch short instructional videos on how to do this. For additional oil fill tips, Minnich Manufacturing provides step-by-step instructions.
- Inspect hydraulic vibrator motor housings. During an inspection, look for unusual wear patterns. Often, these wear patterns will create pinholes, which allow concrete to enter the vibrator housing and seizes the vibrator head permanently.
- Check hydraulic vibrator’s speeds. These speeds can be checked via a Paving Vibrator Monitoring system or digital tachometer. If your vibe is not performing well, sending the vibe to an authorized repair shop to be checked for slippage would be beneficial. Slippage happens after long exposure to hydraulic pressure. The path of hydraulic fluid could wear a slight groove in the aluminum motor housing which would allow hydraulic oil to slip past the gears in the motor. Another possibility for reduced performance would be if a motor seal wears out. Either way, an authorized repair house would be able to test the amount of slippage, repair the hydraulic motor, and offer a warranty on the vibrator.
- Clean dust collector filter regularly. Cleaning out the system’s filter will help to ensure optimum engine performance. Minnich Manufacturing has incorporated a purge button feature on the dust collection system, which reverses the airflow and blasts air through the filter to help keep the filter clean. Use of the dust collection system in wet environments is not advised as the fine dust on the filter and inside the system will gel and harden.
- Reduce downtime
Potential red flags are often uncovered during maintenance tasks that can be repaired or replaced before it becomes a larger issue. To keep your equipment in top condition, follow the recommended maintenance procedures found in your owner’s manual for your specific drill and vibe. For additional help, or to replace parts, contact your local dealer.
Consider sending in your paving vibrators to your manufacturer for repair early in the winter. Minnich Manufacturing has the expertise and tools to service concrete equipment to help lengthen product life span, helping you get the most from your equipment.
Inspect the saw
Before each use, check the saw over for any damage or defects. Look for issues with the power source, the blade, base plate, and blade guard. If your saw is cordless, make sure you have a fully charged battery.
Check the blade
The blade you are using will depend on the type of material you will be cutting. Regardless of the blade type – check for chipped, cracked, or broken teeth. Never use a blade that is broken, rusted, or dull. If you are replacing the blade, be sure to disconnect the saw from its power supply before you make any changes to the saw blade.
Use a speed square (framing square) as a guide for making crosscuts. Place the blade of the saw at your cut mark, then place the square against the edge of the base plate. Using the square as your straight-line guide, start the saw, bring it to full speed and begin to cut while the base plate travels against the edge of the square.
Kickback from a saw can be very dangerous. The chances of kickback happening are much higher when the material being cut is not supported and causes the material to pinch the saw blade. To reduce saw blade pinching, give your material extra support by placing supports under either side of your cut to prevent the material from falling and creating a pinched space.
Creating a rip cut can often be a much longer cut than a crosscut, this is because a rip cut runs parallel (in the same direction) to the wood grain. Much like using the speed square as a guide for a crosscut, a ply-wood board or even a level clamped to your material can be an ideal guide for making a rip cut. Like the crosscut, line up the saw blade, then place the guide against the base plate to create your cutting guide. The clamps will allow your guide to remain in its place while allowing you to use both hands for handling the saw.
Splintering in wood, when cut happens due to the spin of the blade when the saw is cutting. A circular saw spins from the bottom up, this would create splintering on the side of the material facing up while cutting. To avoid creating splinters in a material of high quality or value, place the backside of the cut facing up so that any splintering will happen on the side of the material that is not visible. If the material being cut will be visible from both sides, place the more visible side down, then for the opposite side, score along the cut line with a utility knife to create an edge that will be free of splinters.

Should a tool, battery or charger need to be cleaned to help control the spread of COVID-19, care should be taken to ensure that it is carefully performed to increase effectiveness and prevent damage to the product. This guidance is provided to assist in the safe cleaning of a product.
When cleaning a product, there are a few important things to remember:
- Always unplug any devices and remove batteries prior to cleaning.
- There are different recommendations for batteries compared to tools and chargers. Be sure to follow the correct advice for the product you are cleaning.
- Products should be cleaned in accordance with the cleaning instructions provided in the operator’s manual for the product and then left to rest for 72 hours. This is based on CDC advice that the virus may live on plastic surfaces for up to 72 hours, which suggests that the virus would no longer be harmful after the resting period.
- For tools and chargers only, if the user cannot wait for 72 hours to use the tool or charger, it can first be cleaned in accordance with the cleaning instructions provided in the operator’s manual and then cleaned with a cloth or sponge dampened with a diluted bleach solution* and allowed to air dry. This method is consistent with CDC advice. It is important to adhere to the warnings below:
- Do not use bleach to clean batteries.
Observe the necessary precautions when cleaning with bleach.
- Do not use the tool or charger if you detect degradation of the housing, cord or other plastic or rubber parts of the tool or charger after cleaning with the diluted bleach solution.
- The diluted bleach solution should never be mixed with ammonia or any other cleanser.
- Do not use bleach to clean batteries.
- When cleaning, dampen a clean cloth or sponge with the cleaning material and ensure the cloth or sponge is not dripping wet.
- Gently wipe each handle, grasping surface, or outer surface with the cloth or sponge, using care to ensure liquids do not flow into the product.
- Electrical terminals of products and the prongs and connectors of power cords or other cables must be avoided. When wiping batteries, be sure to avoid the terminal area where contact is made between the battery and the product.
- Allow the product to air dry completely before reapplying power or reattaching the battery.
- People cleaning products should avoid touching their face with unwashed hands and immediately wash their hands or use a proper hand sanitizer before and after cleaning to help prevent contamination.
*A properly diluted bleach solution can be made by mixing:
- 5 tablespoons (1/3rd cup) bleach per gallon of water; or
- 4 teaspoons bleach per quart of water
Please note: This guidance does not apply for cleaning products where there is a risk of other health hazards, such as blood, other blood borne pathogens or asbestos.

With many different options on the market, it can be challenging to know what features to look out for when selecting an impact wrench. This guide provides a brief overview of the technology and outlines some simple steps to help you get started.
Get familiar with the mechanics
An impact wrench, also known as an impact driver or an impact gun, is designed to tighten or untighten bolts. It is commonly used in mechanical and industrial applications, for example when changing tires and disassembling car wheels, or performing maintenance on oil platforms. There are electrical, battery-powered, or pneumatic options available, each associated with different benefits and challenges.
The operating principle is relatively simple. An impact mechanism composed of an anvil, an impactor (hammer) and a spring, enables the wrench to tighten and untighten as required. The tool accumulates energy by the hammer cage over one or more revolutions and once the hammer hits the output shaft (anvil), it creates the tightening or untightening torque.
Assess your requirements
It is good to bear in mind that there is no one-size-fits-all solution. The desired torque range, power requirements and the impact mechanism’s design may vary depending on the job. As the latter affects the weight, vibration, speed and durability of the tool, it can have a considerable impact on user comfort and suitability for the task. To start the selection process, first consider:
- What are you looking for in a tool: is it power, efficiency, ergonomics, freedom of movement, or multi-purpose use?
- Your environment: how are you going to power the tool?
- The torque: range and precision, what does your application require?
- The ergonomics of the product: are the vibration and sound levels, the tool design and the proposed accessories a good fit for the job?
- The clutch type: is the mechanism capable of delivering the power you require?
- The weight and material of the tool: will it be easy to use over long periods and is the material a good match for your working environment?
Take a closer look at tool design
The design of the tool can play a key role in improving productivity. For example, a well-positioned center of gravity is a great benefit, as it enables better support over extended periods, while different handle shapes and trigger positionings can improve user comfort.
Remember that material matters
The material of the tool is another critical consideration. Metallic tools are usually more robust, but also heavy to use over long periods. Composite tools, on the other hand, are much lighter, enabling better maneuverability, but the material has made them less durable. Fortunately, advancements in material development over the last decade have improved the mechanical resistance of composite, improving its strength and making it a good alternative to metal in many applications.
It is good to remember that the clutch housing and the body of the tool can be made of different materials. When you compare tools, make sure you check which part is composite and which is metal. As a rule of thumb, impact wrenches larger than ¾” tend to be made of metal.

Get the torque level right
Always choose a tool with a maximum torque that is superior to the torque needed for your application. This will reduce the time you spend using the tool and the vibrations you are subjected to. The graph below illustrates the different torque values commonly found in manufacturers’ catalogs.
Do you use the right impact wrench?
- Tool torque range
- Optimal torque: Looking at this torque range, this tool is the best choice, ensuring the best productivity ratio. Ideal for intensive use.
- Working torque: Make sure the torque you need for your application is covered in the tool’s working torque range.
- Maximum torque: For a frequent use at this torque level, we recommend choosing a more powerful tool for more productivity and operator comfort.
Beware of overtightening! In some applications, for example when changing tires in small vehicles or trucks, tightening requires precision and torque control. Using tools with torque limited functions, coupled with a torque wrench, will optimize the application without overtightening and damaging the studs.
Christophe Roland, Product Marketing Manager at Chicago Pneumatic
Review bolt size
You can identify the ideal tool square by looking at the size of the thread. If the square is too small compared to the thread, it will not be suitable and is likely to break. However, if the square is too large, it will be too strong and break the screw when tightening it.
Do not ignore ergonomics, sound and vibration
It is vital to pay attention to factors that affect user safety and ergonomics, such as the sound level and vibration. The sound level is usually governed by the ISO15744 standard and the lower the value, the safer the user experience. The same goes for vibration levels, usually governed by ISO28927: lower vibration levels equal a safer and more comfortable user experience. Some impact systems are designed to enable low vibration levels and safety and comfort can also be further enhanced with the use of vibration-absorbing gloves.
By considering these seven points you will improve safety associated with using tools in the workplace, therefore protecting operators. An additional benefit to these responsible practices is that you will improve efficiency too!
Noise and vibration levels are factors to consider when choosing the tool to use for your application. Usually, when using keys below ¾”, operators are more sensitive to noise. However, above 3/4”, vibrations are more important to ponder.
Christophe Roland, Product Marketing Manager at Chicago Pneumatic
Try it out
Knowing what you need to consider when looking for the right impact wrench for your application is a good start, but sometimes reviewing technical values is not enough to enable a well-informed purchase decision. To ensure the tool can meet your needs, it is always a good idea to discuss your requirements with the manufacturer and request a trial. Trying the tool out in your target application will give you confidence that it is a good fit for the task, the environment and ultimately, the way you work.

“Beauty is in the eye of the beholder.” The origin of this phrase traces its roots back to ancient Greece, but the speaker might just as well have been talking about modern stamped concrete. Once that elusive beauty is captured, the trick is to properly maintain your stamped concrete so it remains sound and looks good for many years to come.
Common Causes of Staining
There are many contaminants that can stain concrete or acrylic sealers. Some of the common sources include:
- Decaying leaves that produce tannic acid
- Fertilizers & lawn chemicals
- Rust & oxidation from furniture, buildings, roofs, etc.
- Food & beverage spills
- Grease & oil spills
- Automotive chemicals
Your concrete sealer is durable, resilient and attractive, but it requires some basic effort to minimize stains throughout its serviceable life. Some suggestions include:
- Clean drips and spills as soon as they occur.
- Use a mild detergent if necessary. Don’t use cleaners/degreasers with harsh solvents, as they will damage the sealer.
- Place drip/spill barriers below and in front of grills and other stationary sources of stains.
- Re-paint rusting patio furniture, planters, etc.
- Replace/repair leaky gutters & downspouts that may be sources of oxidized metals, or roofing materials.
- Routinely rinse off your concrete.
- Do not allow mowers, lawn equipment or other potential sources of leaks and drips to dwell on decorative concrete.
Don’t Jump the Gun on Stripping
If you’re sealer is looking a little worn, don’t jump to the conclusion that it needs to be removed. Strippers contain harsh chemicals that pose a health risk, are harmful to lawns and landscaping, and produce residue that can’t be hosed down the drain. As a result, stripping or removal of a concrete sealer should be a last resort.
There is a common misperception that when a decorative sealer loses its gloss, it has also worn away. But decorative sealers can lose their gloss long before they lose the ability to protect your concrete from stains, freeze/thaw cycles, and other means of damage. As a result, concrete sealers are often applied with greater frequency than necessary and tend to “build up.”
Over time, this build up can cause problems of its own, including:
- Loss of “breathability,” resulting in whitening or delamination.
- Bubble formation as solvent is trapped at greater coating depth.
- A “gummy” or incomplete cure from trapped solvent.
- Bubble formation from entrapped air.
Try a Repair First
If your solvent-based sealer has bubbled or exhibits signs of whitening and delamination, the best advice is to repair the coating rather than remove it. These lacquer systems can frequently be re-paired with careful use of xylene (or xylol).
- Power wash the sealer and allow to dry overnight.
- Lightly saturate a small area with xylene and allow to dwell on the sealer for two minutes. This re-solvates the sealer.
- Gently back roll with a solvent- resistant roller cover to break any bubbles or remove whitening/delamination.
- Repeat the process in small areas until the entire area has been repaired.
- Allow the solvent to evaporate and the sealer to cure on the concrete surface.
This process will solve most of the common sealer issues. Some localized spots may require more than one treatment.
Many parts of the country are just emerging from one of the most severe winters in recent memory. The volume of snow and extreme cold has been more than a nuisance; it has indirectly contributed to increased damage to concrete surfaces.
Damage Caused by Ice Melts
The harsh weather resulted in greater use of ice melt chemicals on our roads and walkways. In fact, the volume of ice melt usage was so great that many municipalities and retail stores were unable to maintain sufficient inventory for the increased demand. And although ice melt chemicals are necessary to ensure our safe footing and driving, they do cause damage to our driveways, sidewalks and walkways.
- Each application of an ice melt chemical creates an artificial freeze/thaw cycle as it melts snow and ice, creating water that is eventually absorbed into concrete where it refreezes. As water freezes it expands, damaging concrete surfaces with scaling, spalling and surface delamination.
- Highly absorptive aggregates or “chert” are particularly susceptible to freeze/thaw damage as they soak up the melt water created by ice melt chemicals, freeze and expand, creating readily identifiable “pop outs” at the substrate surface.
- Ice melts that contain chlorides can damage concrete by promoting carbonation, or “chalking”.• Chlorides also migrate to structural rebar, causing corrosion that can delaminate a layer of concrete and create a “pot hole”.
As a result of the severe winter and high consumption of ice melts, damage may be more prevalent this year than most. Use of a penetrating silane or siloxane water repellent such as Aquanil™ Plus 40, Aquanil™ Plus 40-A or Spall Guard™ WB 10% creates an effective barrier to the damaging effects of ice melts and chlorides.
Concrete has a very high compressive strength, but relatively low tensile strength (typically 1/10th its compres-sive strength). As a result, it is particularly susceptible to freeze/thaw damage, particularly during its fi rst winter. The less “mature” concrete is before that fi rst winter, the greater the chance it will suffer freeze/thaw damage. Using a product like Silencure™-A or Silencure™SRT to cure and protect late season pours will help prevent freeze/thaw damage during that critical fi rst winter.
Spring Moisture Problems
Even as winter recedes, spring weather presents challenges of its own. Melting snow, spring rains and higher water tables mean your concrete is constantly wicking moisture from the ground. Because concrete is porous, this water passes through in the form of water vapor, which may overwhelm the Moisture Vapor Transmission (MVT) or “breathability” of a fi lm forming sealer. Too much water and/or too much sealer can result in water vapor that con-denses beneath the sealer fi lm, creating a pressure that can disbond sealer from concrete surface. This phenomenon is often referred to as “whitening” or “frosting” due to its appearance.
In severe cases, the accumulating moisture will create enough pressure to disbond a weak layer of concrete paste, appearing as scaling or spalling.
Some spring weather is so wet that any coating will be overwhelmed by the volume of moisture passing through concrete. In fact, some local geology creates areas that are always wet, or have an excess of ground water. In those cases it may be advisable to consider use of a fully breathable penetrating sealer rather than a film former.
Spring weather also presents unique challenges to water based sealers, which are vulnerable to low temperatures and high humidity. These water based products undergo a process of film formation known as “coalescence”. As water evaporates, discrete acrylic molecules come together (coalesce) to forma film. But in order to do so, they require a minimum energy in the form of temperature (50° F / 10° C). That energy is both a function of ambient air temperature, and substrate temperature.
In the spring it’s common to reach daytime highs in excess of 50° F (10° C), with nighttime temperatures considerably lower. Soil and concrete within the ground, require a lot of time and energy to warm up. As a result, slab on grade concrete generally takes much longer than you think to achieve adequate temperature for a water based product.
Use of water based products in sub-optimum temperatures can result in:
- “Blushing” or a milky appearance within the coating due to incomplete film formation. An incompletely coalesced ï¬ lm may often be repaired by use of a xylene wash within the first 48 hours.
- Complete lack of film formation, in which discrete acrylic particles never coalesce. They simply dry on the concrete surface appearing like powdered sugar. Complete lack of film formation cannot be salvaged. The surface must be swept clean and fresh coating applied.
Remember, it’s not enough that a daytime high reaches 50° F (10° C). Both the air temperature and substrate temperature must be above 50° F (10° C), and remain there long enough, for water based coatings to properly cure.
Stains can occur in concrete and within sealers from a variety of common sources. You may find the tannic acid from decaying leaves have left a tenacious stain. If that happens, try a good power wash. If necessary, judiciously apply a solvent like xylene or acetone on the stain and wipe with a clean, white, lint-free cloth to remove the stain. Afterward, apply a thin coat of sealer over the area if necessary.
Ordinary lawn and garden chemicals such as fertilizers can stain concrete and sealers. The same goes for automotive products such as gasoline, greases, oils, fluids and cleaning products. Be careful when using them to avoid contact with your concrete. Quickly clean any accidental exposures.
Year Round Protection
As the snows recede, spring both reveals damage to concrete and sealers, and begins a host of new sources for damage. Choosing the right high quality sealing product will improve the appearance of your concrete and help protect your investment throughout the year.

What is MX FUEL™?
The new MX FUEL™ Equipment System will be the platform that provides the technology and capability for Milwaukee® to take a giant step into the equipment space. Like the M12™ and M18™ Systems, MX FUEL™ will feature three Milwaukee-exclusive innovations – the POWERSTATE™ Brushless Motor, REDLINK PLUS™ Intelligence, and the MX FUEL™ REDLITHIUM™ Battery Pack – to deliver a platform of equipment solutions designed from the ground-up to exceed the demands of the professional trades.
Why MX FUEL™?
Ever since Milwaukee® first introduced the ability to utilize lithium-ion technology in power tools, a revolution has taken place on jobsites worldwide. The capabilities of cordless technology have been pushed to new limits, providing new solutions that challenge existing perceptions of what can be powered by cordless technology. But while power tools have received considerable benefits from cordless technology, the same cannot be as readily said about light equipment.
Exposure to emissions, vibration, and noise continues to create prevalent health concerns for professionals in the construction trades. The MX FUEL™ Equipment System is the output of years of tireless research and investment in new technology, ground-up development of new batteries, motors, and electronics – all simultaneously developed under one roof.
Designed to take on the very same gas and AC equipment that the professional trades have depended on for years, this system eliminates the emissions, and reduces the overall noise,
vibration, and frustrations of gas maintenance that have been deemed acceptable on jobsites for decades – and additionally eliminates tripping breakers, voltage drops, and trip hazards.
Mortairvent creates a continuous airspace that channels moister away & accelerates drying behind the exterior siding, reducing the chances of rot & toxic mold growth.
The Mortairvent® Mortar Deflection & Ventilation System is a full cavity wall product used to reduce the overall cavity width in ventilated wall assemblies. Mortairvent® combines the benefits of rain screen technology through the use of integrated mortar deflection, drainage and ventilation design. Mortairvent® does not allow mortar blockage in the cavity wall drainage plane due to the heat bonded filter fabric. This dedicated airspace allows proper drainage and convective drying. Mortairvent® is available in .40 in (10mm), .80 in (20mm), and 1.6 in (40mm) thicknesses.
