3M 7010309305 Scotch-brite Unitized Wheel 4 Inch Fine Grit

Product Description

The 3M 7010309305 is a Scotch-Brite unitized abrasive wheel designed for precision deburring and surface finishing of demanding alloys including stainless steel and titanium. At 4 inches in diameter and built with a fine-grit silicon carbide abrasive, this wheel delivers consistent cutting action while remaining softer and more conformable than higher-density convolute wheels. Its layered unitized construction allows it to run in either direction and resist loading, keeping the wheel cooler over extended use. Licensed tradespeople and metalworking professionals install and operate this wheel on bench grinders, right-angle grinders, and portable finishing equipment.

This wheel is suited for finishing intricate shapes, contours, and narrow workpiece geometries where a larger convolute wheel would be impractical. The unitized format allows for much smaller diameters and widths than convolute construction, making it a practical choice for tight tolerances and precision applications. Typical use cases include weld blending, edge deburring, and pre-polish finishing on stainless steel, titanium, and other demanding metal alloys in fabrication, maintenance, and repair environments.

Key Features

• Layered unitized construction runs clockwise or counterclockwise without performance loss
• Silicon carbide abrasive at fine grit for controlled stock removal and smooth finishing
• Resists loading and runs cool, extending service life during continuous use
• Conformable structure follows intricate shapes, contours, and narrow profiles
• Compatible with smaller bench-mounted and portable grinding equipment
• Effective on stainless steel, titanium, and other demanding alloys

Compatibility

Designed as an OEM-style replacement or direct-use abrasive wheel for bench grinders, right-angle grinders, and portable finishing machines that accept 4-inch unitized abrasive wheels.

Installation Notes

Mounting and operation of abrasive wheels should be performed by qualified personnel following ANSI B11 and applicable shop safety standards. Always power down and de-energize the grinder before mounting or removing the wheel. Confirm the spindle speed rating of the equipment does not exceed the maximum RPM rating of the wheel before operating. Inspect the wheel for damage before each use and do not operate a cracked or compromised wheel.
