3M 7100398618 Cut-off Wheel 60+ Grit T27 6 in Case of 10

Product Description

The 3M 7100398618 is a Type 27 cut-off wheel engineered for fast, perpendicular cuts through metal and stainless steel using the outer edge of the wheel. Sold as a case of 10 wheels, each wheel measures 6 inches in diameter, 0.045 inches thick, with a 5/8 in-11 threaded arbor. The abrasive uses 3M Precision Shaped Grain technology, which features sharp angular structures that continuously fracture to expose fresh cutting edges. This design allows the wheel to slice faster, run cooler, and outlast conventional aluminum oxide abrasives. Grit rating is 60 plus. Meets ANSI standards for cut-off wheel safety.

These wheels are suited for metal fabrication, HVAC sheet metal work, plumbing, exhaust system repair, and general mechanical trade applications. Common targets include stainless steel tubing, exhaust pipes, pipe clamps, threaded fasteners, and structural steel. The Type 27 raised-hub design provides clearance for flush and near-flush cutting in tight workspaces, making these a practical choice for service technicians and fabricators working in the field or on a shop bench.

Key Features

• Precision Shaped Grain abrasive continuously fractures to maintain sharp cutting edges throughout the wheel life
• Runs cooler than conventional abrasives, reducing heat discoloration on stainless steel and thin-wall tubing
• Type 27 raised-hub profile supports flush and recessed cutting angles
• 60 plus grit rating balances cutting speed with surface finish on ferrous and non-ferrous metals
• 5/8 in-11 threaded arbor fits standard angle grinders used in HVAC, plumbing, and mechanical trades
• ANSI-compliant construction; case of 10 wheels reduces restocking frequency on active job sites

Compatibility

Designed for use with angle grinders equipped with a 5/8 in-11 threaded spindle; suitable for cutting ferrous metals, stainless steel, and similar materials in trade and fabrication applications.

Installation Notes

Install and service by qualified personnel familiar with angle grinder safety and applicable ANSI B7.1 wheel-mounting procedures. Power down and disconnect the grinder from its power source before mounting or changing the wheel. Inspect each wheel for cracks or chips before use and never exceed the maximum RPM rating marked on the wheel. Appropriate eye, face, and hand protection is required during operation.
