4-1/2" x 1/4" x 7/8" T27 Depressed Center Grinding Wheel For Aluminum - 25 Pack

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

Benchmark Abrasives 4-1/2" x 1/4" x 7/8" T27 depressed center grinding wheels for aluminum are built for aggressive stock removal, weld grinding, edge cleanup, and material reduction on aluminum and other approved nonferrous metals. The full 1/4" wheel thickness provides the working surface needed for sustained grinding, making it a strong choice for fabrication, maintenance, repair, and production environments where substantial material removal is required.

The wheel uses an aluminum oxide and silicon carbide abrasive blend designed for aluminum and other approved nonferrous metals. Its Type 27 depressed-center profile provides practical working clearance for angle-grinder applications such as weld cleanup, beveling, edge preparation, and general surface grinding.

With a 7/8" arbor and a maximum rating of 13,500 RPM, this wheel is designed for compatible 4-1/2" angle grinders equipped with the proper Type 27 grinding guard, flanges, and mounting hardware. Pair it with the Benchmark Abrasives 4-1/2" angle grinder for an all-Benchmark grinding setup when the proper wheel configuration is 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.

Machine Compatibility

Designed for compatible 4-1/2" angle grinders that accept a 7/8" arbor Type 27 grinding wheel and are equipped with the proper grinding guard, flanges, and mounting hardware.

Compatible examples include:

• Benchmark Abrasives BMT-AGBC4570 4-1/2" Angle Grinder (11,000 RPM)
• Makita® 9557PB / 9557PBX1 (11,000 RPM)
• DEWALT® DWE402 (11,000 RPM)
• Bosch® GWS10-45 (11,500 RPM)
• 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 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.

Grinding Performance

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

The aluminum oxide and silicon carbide abrasive blend differentiates this wheel from the standard steel-focused aluminum oxide grinding wheel and makes it the appropriate Benchmark option when working on aluminum applications.

Safety Tips

• Use this wheel for grinding applications.
• Never exceed the wheel's 13,500 RPM maximum speed.
• Use only on materials specifically approved for this wheel.
• 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.
