8 Inch Cutting Wheel
8 Inch cutting wheels, or cut-off wheels, are abrasive wheels designed for clean cuts through metals. Cutting wheels come in two main types; Type 1 and Type 27. Type 1 cut-off wheels are flat for the most cutting depth, while Type 27 cutting wheels have depressed centers to allow better visibility while cutting. The grain that makes up a cutting wheel's composition determines its cutting speed and life span.

Types of 8 Inch Cutting Wheels
There are two basic configurations of 8 inch cutting wheel
Type 41(1): This is a flat cutting wheel that allows for a maximum depth of cut.
Type 42(27): This design features more of a rigid feel while cutting, enhanced operator visibility of the cut, and the ability to flush cut as the raised hub allows for the locking nut to be recessed. These wheels are also available with our 5/8-11 quick change hub for ease of mounting.
Choosing the Right 8 Inch Cutting Wheel
Selection of a wheel for any cutting job involves several factors. The desired end result is usually most important, whether it involves high-speed production cutting, or a precision, fine finish cutting application.
Material: Type of material to be cut: Its hardness, size and shape, quality of cut sought.
Machine: Type to be used: Chop-stroke, oscillating or swing-frame, make and model, size, horsepower, spindle speed, how the workpiece is secured, wet or dry cutting.
Wheel: Dimensional features of wheel currently in use: Diameter, thickness, arbor and reinforcement pattern, manufacturers specifications (name, grade, rpm).
● Use a soft grade when:
Machine has low horsepower.
Good finish is important - fine grains normally used to provide minimum burr.
Operators cut slowly.
● Use a medium grade when:
Softer grades do not provide enough cuts - longer wheel life is required.
Cutting normal materials. Machine horsepower will support faster cutting rates.
● Use a hard grade when:
Maximum wheel life is sought.
Machine has adequate horsepower (1 hp per inch of wheel diameter is recommended).
Burr and finish requirements are minimal. (note that fast cuts will produce a reasonably good finish)
General 8 Inch Cutting Wheel Safety Recommendations
Several best practices and recommendations for safe use apply to 8 inch cutting wheels of all sizes and types
● Use the proper guard: Having the correct guard on the tool is an important part of safe 8 inch cutting wheel use. Right-angle grinders - the most used tool with 8 inch cutting wheels - typically only come with a grinding guard. 8 inch cutting 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 8 inch cutting wheel or a type F42 depressed center 8 inch cutting 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 8 inch cutting wheel.
● Wear the necessary Personal protective equipment (PPE): Personal protective equipment should be worn when using a 8 inch cutting 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 8 inch cutting 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 8 inch cutting 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.
● Don't flex a 8 inch cutting wheel: During a cut, never try to flex or bend the wheel to make a curved cut. This introduces side loading and can fracture the wheel.
● Never grind with a 8 inch cutting wheel: A 8 Inch cutting wheel doesn't have the fiberglass reinforcement that a grinding wheel does, so it can be dangerous to grind with a 8 inch cutting wheel. Only use a 8 inch cutting wheel for cutting. Combination wheels can be used for cutting and grinding and are marked accordingly.
● Don't push a wheel through a cut: 8 Inch cutting 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 can be difficult to cut. In these cases, choose a 8 inch cutting 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 8 inch cutting 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.
Resin-bonded wheels, including portable wheels, should be used within two years from the date of manufacture. This assumes you've stored the wheels according to the manufacturer's recommendations. While it may be possible to use resin-bonded wheels after the two-year mark when they are stored properly, you should always examine any wheels more than two years old. Consider having older wheels inspected or speed-tested to determine if any degradation is present.
To help improve shelf life, store wheels in a dry, protected area free from extreme variations in temperature and far away from solvents. Establish a storage system that encourages you to use your oldest wheels first. And never leave a wheel attached to a tool overnight.
Abrasive Type for 8-Inch Cutting Wheel
8 inch cutting wheel materials do the cutting, and each type of 8 inch cutting wheel offers a different balance of cost, durability, and performance.
Aluminum Oxide: Versatile, inexpensive and durable, aluminum oxide is a good go-to 8 inch cutting wheel for everyday jobs. Aluminum oxide will cut through steel, as well as softer metals like brass, annealed iron, and steel alloys.
Zirconia Alumina: A mix of aluminum oxide and zirconium oxide, this 8 inch cutting wheel is durable and fast. Zirconia is a naturally occuring mineral with extremely high fracture toughness, which produces a high metal removal rate when cutting through hardened materials like tempered steel. Zirconia also offers superior heat dissipation, which can be important when cutting through thick steel plate.
Silicon Carbide: This super sharp 8 inch cutting wheel makes quick work of soft materials. Silicon carbide naturally has a very sharp edged grain. The cutting material microscopically fractures as it wears, creating new razor-edged cutting faces throughout the wheel's life.
Ceramic Aluminum Oxide: Ceramic wheels are extremely durable and versatile. This 8 inch cutting wheel is made by heating aluminum oxide in a kiln, a process known as sintering. 8 inch cutting wheel ceramics are designed to microfracture in a controlled manner. The glass-like ceramic aluminum oxide grains continuously shatter as they cuts, keeping the cutting edge sharp.
● Wide range of application for various materials with different hardness's.
● Long lifetime as well as low wear of the 8 inch cutting wheel.
● Premium abrasive particles enable the finest cutting surfaces, which shortens the following grinding steps.
● The synthetic resin bond allows dull abrasive particles to break out evenly during the cutting process.
