4-1/2" X 1/4" X 5/8"-11 T27 HIGH PERFORMANCE 4X CERAMIC DEPRESSED CENTER GRINDING WHEEL - 10 PACK
Benchmark Abrasives 4-1/2" x 1/4" x 5/8"-11 T27 high performance 4X ceramic depressed center grinding wheels are built for demanding stock removal, weld grinding, beveling, edge cleanup, and general metal fabrication. The full 1/4" wheel thickness provides the substantial working surface needed for sustained grinding, while the threaded hub makes installation straightforward on compatible angle grinders.
Built with ceramic abrasive grain, this premium Type 27 wheel is designed for grinding steel, stainless steel, and other approved metals. The ceramic construction gives the 4X family its high-performance positioning for fabrication, maintenance, repair, and production environments where aggressive material removal and consistent grinding action are required.
The 5/8"-11 threaded hub mounts directly onto compatible 4-1/2" angle grinders. With a maximum wheel rating of 13,300 RPM, this wheel works with suitable corded and cordless grinders equipped for Type 27 hubbed grinding wheels. Use the proper grinding guard and hubbed-wheel mounting setup.
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.

Machine Compatibility
Designed for compatible 4-1/2" angle grinders with a 5/8"-11 spindle that are approved for Type 27 grinding wheels and operate at 13,300 RPM or less.
Metabo® WEPBA 17-125 Quick RT DS (10,000 RPM, North American version)
Milwaukee® 2880-20 (8,500 RPM)
Use the proper Type 27 grinding guard and the manufacturer's 5/8"-11 hubbed-wheel mounting instructions. Check full thread engagement and guard coverage; do not clamp the threaded hub between plain-arbor wheel flanges.
Other models may also be compatible when they meet the same wheel and setup requirements.
Grinding Performance
The ceramic abrasive grain and 1/4" wheel profile are designed for sustained material removal, weld grinding, beveling, and edge preparation. This is a dedicated grinding wheel intended for demanding applications where a premium abrasive construction is preferred.
The 5/8"-11 threaded hub simplifies installation and wheel changes compared with plain-arbor grinding wheels, while the depressed-center shape provides practical working clearance during grinding.
The 4X designation identifies Benchmark Abrasives' premium ceramic bonded-abrasive family. It should not be interpreted as a guaranteed four-times service-life claim unless specific comparative testing supports that statement.
Safety Tips
Use this wheel for grinding applications.
Never exceed the wheel's 13,300 RPM maximum speed.
Choose a grinder with a maximum rated speed at or below 13,300 RPM.
Confirm the grinder uses a compatible 5/8"-11 spindle.
Always use the proper Type 27 grinding guard specified for the grinder and wheel configuration.
Make sure the threaded hub is fully and correctly engaged before operation.
Use the grinder's side handle for control during grinding.
Inspect the wheel before use and do not operate cracked, chipped, damaged, or improperly stored wheels.
Avoid excessive pressure and allow the abrasive to perform the work.
Wear appropriate eye and face protection, hearing protection, gloves, and other PPE required for the application.
