4-1/2" X 1/4" X 5/8"-11 T27 HUB DEPRESSED CENTER GRINDING WHEEL FOR ALUMINUM - 10 PACK
Benchmark Abrasives 4-1/2" x 1/4" x 5/8"-11 T27 hub 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, while the threaded hub makes installation straightforward on compatible angle grinders.
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 applications such as weld cleanup, beveling, edge preparation, and general surface grinding without relying on a steel-focused abrasive formulation.
The 5/8"-11 threaded hub mounts directly onto compatible 4-1/2" angle grinders with a 5/8"-11 spindle. With a maximum rating of 13,500 RPM, this wheel pairs well with the Benchmark Abrasives 4-1/2" angle grinder when the proper Type 27 grinding guard and operating setup 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.

Materials & Applications
Recommended Materials:
Aluminum
Other approved nonferrous metals
Best For:
Aluminum weld cleanup
Stock removal
Beveling
Edge grinding
Surface cleanup
Aluminum fabrication
Equipment repair
Maintenance applications
General-purpose nonferrous grinding
Machine Compatibility
Designed for compatible 4-1/2" angle grinders with a 5/8"-11 spindle that are approved for Type 27 grinding wheels.
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 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, while the 5/8"-11 threaded hub simplifies wheel installation and changes compared with a plain-arbor setup.
Safety Tips
Use this wheel for grinding applications.
Never exceed the wheel's 13,500 RPM maximum speed.
Confirm the grinder uses a compatible 5/8"-11 spindle.
Use only on materials specifically approved for this wheel.
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.
