4-1/2" x .040 x 5/8"-11 T27 Depressed Center Thin Cut-off Wheel - 10 Pack

4-1/2" X .040" X 5/8"-11 T27 DEPRESSED CENTER THIN CUT-OFF WHEEL - 10 PACK

Benchmark Abrasives 4-1/2" x .040" x 5/8"-11 T27 depressed center thin cut-off wheels combine fast, precise cutting with the convenience of a threaded hub. The ultra-thin .040" profile produces a narrow kerf with minimal material removal, while the 5/8"-11 hub threads directly onto compatible angle grinder spindles for a straightforward mounting setup.

Made with aluminum oxide abrasive grain, these Type 27 wheels are designed for cutting steel, stainless steel, and other approved metals. The depressed-center profile provides additional mounting clearance compared with a flat Type 1 wheel while remaining strictly a cutting wheel—ideal for tubing, pipe, sheet metal, fasteners, fabricated assemblies, and everyday fabrication and repair work.

The threaded 5/8"-11 hub makes this wheel an excellent match for compatible 4-1/2" angle grinders, including the Benchmark Abrasives 4-1/2" angle grinder. With a maximum rating of 13,500 RPM, it delivers a convenient hubbed option for fabricators who want quick wheel installation without a separate 7/8" arbor 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.

Quantity: 10 Cut-Off Wheels

Machine Compatibility

Designed for compatible 4-1/2" angle grinders with a 5/8"-11 spindle and an approved hubbed Type 27 cutting-wheel setup.

Compatible examples include:

• Benchmark Abrasives BMT-AGBC4570 4-1/2" Angle Grinder (11,000 RPM)
• Makita® 9557PB / 9557PBX1 (11,000 RPM)

• Metabo® WEPBA 17-125 Quick RT DS (10,000 RPM, North American version)
• Milwaukee® 2880-20 (8,500 RPM)

Use the grinder manufacturer's approved 5/8"-11 hubbed-wheel mounting setup and cutting guard. Check full thread engagement and that the wheel stays within the guard; 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.

Cutting Performance

The .040" profile creates a narrow kerf with minimal material removal, making it well suited for fast, controlled cutting across common fabrication and repair applications.

The threaded hub simplifies mounting compared with a plain-arbor wheel, while the depressed-center shape provides additional clearance around the mounting area. Despite its Type 27 shape, this wheel is designed strictly for cutting.

Safety Tips

• Use this wheel for cutting only. Never grind with the side or face of the wheel.
• Never exceed the wheel's 13,500 RPM maximum speed.
• Confirm the grinder uses a compatible 5/8"-11 spindle.
• Always use the proper cut-off wheel guard specified for the grinder and wheel configuration.
• Make sure the threaded hub is fully and correctly engaged before operation.
• Inspect the wheel before use and do not operate cracked, chipped, damaged, or improperly stored wheels.
• Keep the wheel straight in the cut and avoid side loading.
• Do not force or twist the wheel through the workpiece.
• Wear appropriate eye and face protection, hearing protection, gloves, and other PPE required for the application.
