3M 7100187301 Scotch-brite Exl Unitized Wheel 3 in Fine Grit

Product Description

The 3M 7100187301 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing operations on metal alloys, plastics, and composites. Built with silicon carbide abrasive at a fine grit rating, this wheel uses a soft, conformable construction that keeps the abrasive in consistent contact with the workpiece surface. The layered, unitized body resists loading and smearing, producing cleaner finished surfaces with minimal heat buildup. Weighing 1.279 pounds, it suits use on bench grinders, die grinders, and automated robotic finishing systems where consistent surface contact is critical.

This wheel is suited for fabrication shops, maintenance and repair operations, and automated production lines where controlled deburring and surface finishing of complex-shaped parts is required. Fine grit makes it appropriate for final-stage finishing and light deburring rather than aggressive stock removal. The conformable structure allows it to follow contours on irregularly shaped workpieces, including parts processed in robotic or CNC finishing cells. It can be dressed at the wheel edge to maintain cutting performance throughout its service life.

Key Features

• Silicon carbide abrasive at fine grit for controlled finishing and light deburring
• Soft, conformable unitized construction maintains abrasive contact on complex part geometries
• Operates in clockwise or counterclockwise rotation for flexible machine mounting
• Resists smearing for cleaner surface results and reduced prep time between passes
• Minimizes heat buildup, reducing thermal impact on heat-sensitive base materials
• Wheel edge can be dressed to restore cutting action and extend usable wheel life

Compatibility

Designed for use on metal alloys, plastics, and composites; compatible with bench grinders, die grinders, and robotic finishing equipment that accept 3 inch diameter unitized wheels.

Installation Notes

Mounting should be performed by a qualified operator following the grinder or tool manufacturer's specifications for maximum operating speed and arbor size. Always power down and de-energize the machine before mounting or removing the wheel. Inspect the wheel for damage before each use and do not operate beyond the rated RPM. Eye protection and appropriate PPE are required during operation per standard shop safety practices.
