Benchmark Abrasives 6" x .040" x 7/8" T27 high performance 4X ceramic cutting wheels combine the cutting reach of a 6" wheel with an ultra-thin .040" profile and premium ceramic abrasive grain. The result is a narrow, controlled cut with minimal material removal for demanding fabrication, welding, maintenance, and production applications where cutting speed, reach, and efficiency are important.
Built with ceramic abrasive grain, these Type 27 depressed-center wheels are designed for cutting steel, stainless steel, and other approved metals. The 6" diameter provides additional cutting depth compared with smaller grinder wheels, while the .040" profile keeps the kerf narrow for tubing, pipe, sheet metal, structural components, fabricated assemblies, and repetitive shop cutting.
With a 7/8" arbor and a published maximum speed of 13,500 RPM, this wheel is intended for compatible 6" angle grinders specifically approved for Type 27 bonded cut-off wheels. The machine must meet the wheel's diameter, speed, arbor, guard, flange, and mounting requirements before use.
Bottom line, these cut off wheels offer LESS cutting resistance for fast work, LESS work piece waste, LESS vibration, LESS burrs and sparks and LESS dust than the competition.
Available Quantities: 5-Wheel Sampler Pack or 25-Wheel Standard Pack

Machine Compatibility
Designed for compatible 6" angle grinders that accept a 7/8" arbor Type 27 cut-off wheel and are specifically approved for the wheel's diameter and operating speed.
Compatible examples include:
-
Makita® GA6020YX1 (10,000 RPM)
-
Bosch® GWS13-60 (9,300 RPM)
-
Milwaukee® 2980-20 (9,000 RPM)
-
DEWALT® DCG418 (9,000 RPM)
Use the grinder manufacturer's cutting guard and flanges specified for this Type 27 wheel. Match wheel size, thickness and arbor, and keep the machine's maximum speed at or below the wheel rating. Other models may also be compatible when they meet the same wheel and setup requirements.
Do not use this wheel on a smaller grinder simply because the 7/8" arbor fits. Machine compatibility must be established for the full 6" wheel diameter and operating setup.
Cutting Performance
The combination of a 6" diameter and .040" cutting profile provides additional reach without giving up the narrow kerf expected from a thin cut-off wheel. This makes it especially useful when larger tubing, pipe, structural material, or fabricated components require more cutting depth than smaller wheels provide.
The 4X is Benchmark Abrasives' premium ceramic cut-off wheel family, built for fast, aggressive cutting in demanding fabrication and metalworking applications.
Despite its Type 27 depressed-center shape, this wheel is designed strictly for cutting and must not be used for face grinding or side loading.
Safety Tips
- Use this wheel for cutting only. Never grind with the side or face of the wheel.
- Never exceed the wheel's published 13,500 RPM maximum speed.
- Use only on machines specifically approved for 6" bonded abrasive cut-off wheels.
- Always use the proper cut-off wheel guard specified for the grinder and wheel configuration.
- Use the correct flanges and mounting hardware specified by the grinder manufacturer.
- Inspect the wheel before use and do not operate cracked, chipped, damaged, or improperly stored wheels.
- Keep the wheel straight in the cut and avoid side loading.
- Do not force or twist the wheel through the workpiece.
