3M 7100048882 Scotch-brite Exl Unitized Wheel Fine Grit

Product Description

The 3M 7100048882 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing metal alloys, plastics, and composites. Built with a soft, conformable construction, the wheel maintains consistent abrasive contact across irregular and complex part geometries. The abrasive media is silicon carbide at a fine grit rating, making it well suited for light material removal, edge refinement, and surface preparation before coating or finishing. At 2 inches in diameter and weighing 0.21 pounds, this wheel mounts on standard bench grinders, die grinders, or automated robotic finishing systems used in fabrication and metalworking shops.

This unitized wheel is appropriate for both manual and automated finishing operations in light industrial, fabrication, and job-shop environments. It handles ferrous and non-ferrous metal alloys along with many plastics and composites. Its low heat generation makes it a reliable choice when working with heat-sensitive materials that could warp, discolor, or lose temper under aggressive abrasive contact. Machinists, fabricators, and finishing technicians are the primary users of this product.

Key Features

• Silicon carbide abrasive at fine grit for controlled edge finishing and surface refinement
• Soft, conformable unitized construction keeps abrasive in contact with complex or curved part profiles
• Operates clockwise or counterclockwise, compatible with reversible spindle tooling
• Resists smearing for cleaner cut surfaces and reduced post-process preparation
• Minimizes heat build-up to protect heat-sensitive workpiece materials
• Wheel edge can be dressed to maintain consistent deburring and polishing performance

Compatibility

Designed as an OEM-style replacement or direct-use abrasive wheel for bench grinders, die grinders, and robotic finishing spindles accepting 2-inch diameter unitized wheel arbors in metal fabrication and finishing applications.

Installation Notes

Installation should be performed by a qualified machinist or finishing technician familiar with abrasive wheel mounting procedures. Power down and lock out the tool before mounting or removing the wheel. Confirm the tool RPM rating meets or exceeds the wheel speed rating before operation. Inspect the wheel for damage before each use and never operate a cracked or compromised abrasive wheel.
