What are Cut Off Wheels For Metal
Cut-off wheels, otherwise known as cutting wheels, differ from grinding wheels in terms of purpose and construction. Grinding wheels are abrasive in order to scrape away large chunks of material on a workpiece at a shallow angle; however, cut-off or cutting wheels are usually used for precise 90-degree cuts. Cut-off wheels are specifically made for precision cutting and come in various dimensions, thicknesses, and abrasive materials to suit diverse requirements. Their thin blades enable a precise cut that is ideal for slicing through metal sheets or pipes with elaborate designs.
Benefits of Cut Off Wheels For Metal

Types of Cut Off Wheels For Metal
Cut Off Wheels For Metal come in a few different types. Some common types are type 1, type 27, type 41, and type 42, where the various numbers signify the wheels' different shapes and properties.
Type 1 Cut Off Wheel (Type 41 Cut Off Wheel)
A type 1 cut-off wheel, also known as a type 41 cut-off wheel, is completely flat. It is typically considered the most efficient type of wheel for general all-purpose cutting. Because it lacks a depressed center, it provides more cutting surface and minimizes interference with the workpiece. The flat profile helps create deep 90-degree cuts into a workpiece. It allows for the maximum depth of a 90-degree cut at the expense of a small amount of visibility for the operator. Though their straight profile and the way they mount close to the guard can diminish visibility for the operator, type 1 cutting wheels are exceptionally useful in grinders, die grinders, high-speed saws, stationary saws, and chop saws.
Type 27 Cut Off Wheel (Type 42 Cut Off Wheel)
Instead of being completely flat, a type 27 cut-off wheel, also known as a type 42 cut-off wheel, has a depressed center. The depressed center allows for added clearance when the operator is working at a constrained angle, though it gives the wheel limited cutting ability when working around corners, profiles, or extrusions. The depressed shape allows for a raised hub as well to hold the wheel securely in place. The profile of a depressed-center cutting wheel gives the operator a better view of the cut, and it provides the ability to flush-cut because the raised hub means the locking nut can be recessed. Type 27 cutting wheels are designed for right angle grinders.
Safety Recommendations For Using Cut Off Wheels For Metal
Cut-off wheel safety is especially important since these abrasives are used on tools that run at high speeds. When a user uses a cut-off wheel incorrectly or uses a damaged wheel, it can break apart and throw sharp projectiles at a high-speed rate. This makes it critical to pay attention to the condition of cut-off wheels and follow best practices to use these products safely and efficiently. Consider some tips for safely using small, standard, and large cut-off wheels.
Use the Proper Guard
Having the correct guard on the tool is an important part of safe cut-off wheel use. Right-angle grinders - the most used tool with cut-off wheels - typically only come with a grinding guard. Cut-off wheels, however, require a cutting guard with a half-moon-shaped, 180-degree coverage to provide added protection for the user. Using a grinding guard with a type F41 flat cut-off wheel or a type F42 depressed center cut-off wheel does not provide that additional protection. What is even worse is not using a tool guard at all. Always have the proper guard in place when using a cut-off wheel.
Wear the Necessary Personal Protective Equipment (PPE)
Personal protective equipment should be worn when using a cut-off wheel. PPE includes safety glasses, a face shield, ear protection, gloves, flame-resistant clothing, a leather apron, and safety shoes. Hard hats and/or welding caps can also protect the head from sparks during metal cutting.
Conduct a Visual Inspection
Inspect the cut-off wheel and tool before use. Replace with a new wheel if there are cracks or other signs of wear or damage. Even if the wheel is still on the tool, the tool could have been dropped or knocked off the tool rack, so it's important to always check for damage before use. Also, jog the tool for a few seconds before using it to ensure it's running true.
Mount the Wheel Correctly
Most cut-off wheels have a stamped metal ring around the wheel hub. The wheel should be mounted with that stamped insert facing the spindle on the motor side of the tool. This will provide a flush mount because there is less chance for grit or abrasive debris to be present on that side of the wheel.
Secure the Workpiece
Be sure the workpiece is held tightly in a vice or clamped so there's no chance it will move, bend, or roll once the cut is started. If the workpiece moves during the cut, it could twist and pinch the wheel, potentially causing it to break apart.
Never Grind With a Cut-Off Wheel
A cut-off wheel doesn't have the fiberglass reinforcement that a grinding wheel does, so it can be dangerous to grind with a cut-off wheel. Only use a cut-off wheel for cutting. Combination wheels can be used for cutting and grinding and are marked accordingly.
Don't Push a Wheel Through a Cut
Cut-off wheels should only have the weight of the tool as they go through a cut. Forcing the wheel with unnecessary pressure can cause the wheel to slip and bind. Too much pressure also decreases product life.
Use a Better Abrasive for Harder Materials
Some specialty metals like titanium or Inconel can be difficult to cut. In these cases, choose a cut-off wheel with a higher-performing abrasive grain like a ceramic. This helps you cut efficiently and reduces the possibility of the wheel glazing due to excessive heat.
Watch the Spark Path
Sparks are created with any type of cut-off wheel. The spark path can be altered depending on the approach used for the cut. Be mindful of the spark path and any items that could be damaged or coworkers who are in the area.
Wheel Type (T1/T27)
An angle grinder uses two types of cutting wheels: Type 1 (flat wheel), and Type 27 (depressed center wheel). Type 1 Cutting Wheels are utilized for the general cutting of metals. Type 1 cutting wheels are flat wheels that do not have a depressed center so they can provide a large cutting surface.Type 27 Cutting Wheel contains a depressed center so, they are also known as the depressed center wheels. Type 27 wheels are perfect for cutting tight curves and hard areas.
Wheel Grain Quality
Among all other abrasive grains, Aluminum oxide is the most commonly used grain in the manufacturing of cutting wheels. This abrasive grain has a fast cut-rate extensive lifespan and produces a rapid, smooth, and easy-to-control cut. Aluminum oxide grains are perfect for grinding stainless steel, hard steel, iron, and other metals.
Size
With cutting wheels, the tool the operator has access to will often determine the wheel size, and selecting the correct size for the given application is also essential. Choosing the correct size involves calculating the right rate of revolutions per minute (RPMs) - the RPM rating of the cutting wheel should match or exceed the RPM rating on the grinder that will use it. In addition to verifying the RPM rating, it is also important to ensure that the wheel fits on the tool without interfering with or removing the guard.
●Diameter: A wheel's RPM rating tends to correspond with its diameter and the tool it is designed for. Common cutting wheel diameters range from 2 to 4 inches for die grinders, 4 to 9 inches for angle grinders, and 12 to 20 inches for chop, stationary, or high-speed saws.
●Thickness: The right wheel thickness often depends on the precision and accuracy necessary for the cut. For a highly precise cut, a thinner wheel can perform with greater accuracy and precision. They cut more quickly and generate less heat. Thinner wheels also remove less material with each cut, which is ideal when making repairs or fitting up parts. The tradeoff is that they tend not to last as long as thicker wheels under identical conditions. In applications where precision and accuracy are not as critical but longevity is, a thicker wheel may be suitable.
Cutting Material
●For Aluminum: Aluminum is a lightweight metal. Its hardened form is made by processing it with other metals. Along with the various benefits of aluminum, there are also some difficulties while working. Aluminum has a low melting point and abrasive resistant nature. Therefore, cutting aluminum requires a strong cutting wheel that lasts longer and works efficiently.
●For Stainless Steel: Stainless steel is an alloy ( of iron, chromium, and carbon). This chromium provides a corrosion-resistant coating on metals. Although stainless steel resists rust and oxidation, still precautions must be taken during aluminum fabrication and processing. To avoid contamination of the metal workpiece, you need the right bonded abrasive wheel. Ceramic cutting wheels are perfect to cut stainless steel.
● For Hard Metals: Cutting hard metal like titanium, hardened steel, nickel alloy, requires a cutting wheel with extensive life and high cut-rate. Ceramic-based cutting wheels are capable of cutting through hard metal with more efficiency. Ceramic cutting wheels are designed and bonded with ceramic abrasive grain. In ceramic abrasive, granules are composed of crystalline structures. This crystalline structure of grain has numerous self-sharpening cutting edges that cut faster than other abrasive grains. As a result, the material removal rate (MRR) of ceramic cutting wheels is high.
●For Steel: Cutting steel is quite easier than aluminum and stainless steel. As we know, Wheel thickness is the most important factor while choosing a metal cutting tool. Thin cutting wheels are a perfect choice for cutting steel. The best thin cutting wheels range from thin 0.045" inch or ultra-thin 1mm. Zirconia and aluminum oxide bonded cutting wheels are best for cutting through steel.
