3M 7100188590 Unitized Abrasive Wheel 2 in Silicon Carbide

Product Description

The 3M 7100188590 is a unitized abrasive wheel designed for smoothing, deburring, and finishing operations on metal alloys, plastics, and composites. Built with a soft, conformable construction, the wheel maintains consistent abrasive contact across irregular and complex part geometries. Silicon carbide abrasive grain at a fine grit level delivers controlled material removal without aggressive cutting, making it well suited for surface finishing and edge refinement where dimensional tolerance matters. The layered, unitized structure holds its form under repeated use and resists smearing, leaving cleaner surfaces with less secondary preparation required.

This wheel is used in metalworking, fabrication, and finishing operations across industrial and trade settings. It is suited for bench grinders, die grinders, and automated or robotic finishing systems where consistent conformability is required. Applications include deburring cut edges, blending weld seams, and final surface finishing on machined components. The fine grit designation makes it appropriate for finishing passes rather than heavy stock removal. Minimized heat build-up during operation reduces the risk of thermal distortion or discoloration on heat-sensitive materials.

Key Features

• Silicon carbide abrasive at fine grit for controlled finishing and deburring
• Soft, conformable unitized construction maintains abrasive contact on complex shapes
• Operates in both clockwise and counterclockwise directions for versatile machine mounting
• Resists smearing for cleaner surface results and reduced prep time
• Minimizes heat build-up, protecting heat-sensitive workpiece materials
• Wheel edge can be dressed to maintain cutting performance over time

Compatibility

Designed for use with standard bench grinders, die grinders, and robotic finishing equipment that accept 2 inch diameter unitized wheels. Suitable for use on metal alloys, many plastics, and composite materials.

Installation Notes

Mounting and operation should be performed by personnel familiar with abrasive wheel safety protocols. Verify that the spindle speed of the drive tool does not exceed the maximum rated RPM marked on the wheel or its packaging before mounting. Power down and disconnect the tool from its power source before installing or changing the wheel. Inspect the wheel for cracks or damage prior to each use and discard any wheel that shows visible defects.
