3M 7100075531 Unitized Abrasive Wheel 3 Inch Silicon Carbide

Product Description

The 3M 7100075531 is a 3-inch diameter unitized abrasive wheel from the Standard Abrasives 600 Series, designed for medium-pressure finishing and polishing on flat and contoured workpiece surfaces. Built with silicon carbide mineral bonded into a soft-to-medium density open web construction, it removes surface imperfections and refines finishes without loading up or glazing over during extended use. The open web structure resists loading, extending service life on both ferrous and non-ferrous base materials. This wheel is a step up in edge durability from the 500 Series, making it well suited for applications where consistent edge performance and longer abrasive life are priorities.

This wheel is used in fabrication, maintenance, and finishing operations where controlled surface refinement is required on flat stock, tubing, castings, or formed components. It works on standard steels, stainless steel, aluminum, exotic metals, titanium, and composite materials. The wheel runs in both clockwise and counterclockwise directions, giving technicians and machinists flexibility when mounting it on bench grinders, die grinders, or automated finishing equipment. Typical users include metal fabricators, maintenance machinists, aerospace technicians, and general manufacturing personnel.

Key Features

• Soft-to-medium density construction suited for medium-pressure finishing and polishing applications
• Silicon carbide mineral works on ferrous metals, non-ferrous metals, exotic alloys, titanium, and composites
• Greater edge durability than 500 Series wheels, delivering improved cut and extended abrasive life
• Bidirectional operation — runs clockwise and counterclockwise for increased tool and machine compatibility
• Open web design resists loading for longer service intervals between wheel changes

Compatibility

Designed as a unitized wheel replacement for medium-pressure surface finishing and polishing operations; compatible with die grinders, bench grinders, and automated finishing machines that accept 3-inch diameter unitized wheels.

Installation Notes

Installation of abrasive wheels should be performed by qualified personnel following ANSI B7.1 safe-use guidelines. Verify that the spindle speed of the tool does not exceed the maximum rated RPM marked on the wheel before mounting. Power down and lock out the tool before mounting or removing the wheel. Inspect the wheel for cracks or damage prior to each use and do not use a damaged wheel.
