3M 7100089708 Scotch-brite EX2 Deburring Wheel 8 Inch Fine

Product Description

The 3M 7100089708 is a convolute-constructed deburring wheel from the Scotch-Brite EX2 line, engineered for mid-range aggressiveness and hardness across a broad range of surface finishing tasks. It is built for deburring, edge radiusing, blending, polishing, and finish work on metal alloys, many plastics, and composites. The convolute construction delivers consistent abrasive action and resists smearing, producing cleaner surfaces with less prep work between passes. At 8 inches in diameter and fine grit, it suits bench-mounted and pedestal grinder setups where controlled, repeatable results matter. Fabricators, machinists, and metalworking professionals are the primary users of this wheel.

This wheel is suited for industrial and light manufacturing environments where burr removal and surface blending are routine operations. It handles clockwise and counterclockwise rotation, making it compatible with a wide variety of bench grinders and deburring machines. The layered, unitized construction maintains its profile under load, and the wheel edge can be dressed to restore effectiveness when working sharp edges or stubborn metal burrs. It is appropriate for use on ferrous and non-ferrous metals as well as select plastics and composite materials.

Key Features

• Convolute construction delivers mid-range hardness and aggressiveness for controlled deburring and finishing
• Operates in both clockwise and counterclockwise directions for flexible machine compatibility
• Wheel edge is dressable, restoring cutting action for deburring, finishing, and polishing tasks
• Resists smearing for cleaner surface results and reduced prep time between operations
• Minimizes heat buildup, reducing risk of thermal damage on heat-sensitive base materials
• Effective on all metal alloys, many plastics, and composite materials

Compatibility

Designed for use on bench grinders and pedestal deburring machines accepting 8-inch diameter convolute wheels; suitable for ferrous metals, non-ferrous metals, many plastics, and composites.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety practices. Ensure the grinder or deburring machine is fully powered down and locked out before mounting or removing the wheel. Confirm the machine spindle speed does not exceed the maximum rated RPM marked on the wheel. Follow ANSI B7.1 safe mounting procedures, including proper flange sizing and guard clearance, before returning the machine to service.
