4-1/2" X 1/4" X 7/8" T27 High Performance 4x Depressed Center Grinding Wheel - 25 Pack

4-1/2" X 1/4" X 7/8" T27 HIGH PERFORMANCE 4X CERAMIC DEPRESSED CENTER GRINDING WHEEL - 25 PACK

Benchmark Abrasives 4-1/2" x 1/4" x 7/8" 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 applications where aggressive material removal is the priority.

Built with ceramic abrasive grain, this premium Type 27 wheel is designed for grinding steel, stainless steel, and other approved metals. Ceramic grain gives the 4X family its high-performance positioning for demanding fabrication, maintenance, repair, and production environments where operators need strong cutting action and consistent grinding performance.

With a 7/8" arbor and a maximum speed of 13,300 RPM, this wheel fits compatible 4-1/2" angle grinders equipped with the proper Type 27 grinding guard and mounting hardware. Pair it with the Benchmark Abrasives 4-1/2" Angle Grinder for an all-Benchmark grinding 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.

Use the proper Type 27 grinding guard and the manufacturer's flanges for a 1/4" thick, 7/8" arbor wheel. Check wheel size and mounting, and keep the grinder's maximum rated speed at or below the wheel rating.

Always verify the exact grinder's wheel diameter, speed, arbor, guard, flange, and Type 27 grinding-wheel requirements before use.

Grinding Performance

The ceramic abrasive grain and 1/4" wheel profile are built 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 4X ceramic construction is built for aggressive grinding and consistent performance in demanding fabrication work.

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.
• Always use the proper Type 27 grinding guard specified for the grinder and wheel configuration.
• Use the correct flanges and mounting hardware specified by the grinder manufacturer.
• 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.
