4-1/2" x 1/4" x 7/8" T27 Depressed Center Grinding Wheel - 25 pack

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

Benchmark Abrasives 4-1/2" x 1/4" x 7/8" T27 depressed center grinding wheels are built for aggressive stock removal, weld grinding, edge cleanup, and general metal fabrication. The full 1/4" wheel thickness provides the durability and working surface needed for sustained grinding applications where thin cut-off wheels or lighter finishing abrasives are not appropriate.

Made with aluminum oxide abrasive grain, these Type 27 wheels are designed for grinding steel, stainless steel, and other approved metals. The depressed-center profile gives operators practical working clearance for common angle-grinder applications, making this a dependable choice for weld removal, beveling, surface cleanup, and material reduction in fabrication, maintenance, repair, and construction environments.

With a 7/8" arbor and a 13,500 RPM maximum rating, this wheel is designed for 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 when the correct guard, flanges, and wheel configuration are used.

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. Other models may also be compatible when they meet the same wheel and setup requirements.

configuration before operation.

Grinding Performance

The 1/4" wheel profile is designed for grinding rather than cutting. Its thicker construction provides the working surface needed for sustained material removal, weld cleanup, edge preparation, and beveling.

Use the wheel at the grinding angle specified for the wheel and machine setup. Do not apply thin cut-off-wheel techniques to this product; it is designed to work on the grinding face within its intended Type 27 application.

Safety Tips

• Use this wheel for grinding applications.
• Never exceed the wheel's 13,500 RPM maximum speed.
• 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.
• Do not use the wheel in an application or position not approved by the grinder and wheel manufacturer.
• Wear appropriate eye and face protection, hearing protection, gloves, and other PPE required for the application.
