3M 7100188516 Scotch-brite Exl Unitized Wheel 6 in Ao

Product Description

The 3M 7100188516 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and finish work on metal alloys, plastics, and composites. The unitized, layered construction holds aluminum oxide abrasive mineral in a soft, conformable matrix that maintains consistent contact with the workpiece surface. At 6 inches in diameter and mounting on a 1/2-inch arbor, this wheel fits standard bench grinders and die grinders used in fabrication and finishing shops. The wheel resists smearing, minimizes heat build-up, and can run in either clockwise or counterclockwise rotation. Machinists, metal fabricators, and production finishing technicians are the primary users.

This wheel is suited for edge deburring, surface blending, and light finishing of metal alloys including stainless steel, aluminum, and carbon steel, as well as many plastics and composite materials. The conformable construction makes it effective for contoured or complex-shaped parts, including those processed in robotic or automated finishing systems. It is applicable in both light-production and bench-top manual operations where heat control and surface cleanliness are priorities.

Key Features

• Unitized, layered construction allows clockwise or counterclockwise operation
• Conformable matrix keeps abrasive in contact with complex and contoured part geometry
• Aluminum oxide mineral provides consistent cut on metals, plastics, and composites
• Minimizes heat build-up to protect heat-sensitive workpiece materials
• Resists smearing for cleaner finished surfaces with less follow-up preparation
• Wheel edge can be dressed to restore cutting profile for deburring and polishing

Compatibility

Designed for use on bench grinders and right-angle or straight die grinders accepting a 1/2-inch arbor. Suitable for finishing metal alloys, many plastics, and composite materials in manual and robotic processing applications.

Installation Notes

Installation should be performed by a qualified technician following the grinder and wheel manufacturer's safety guidelines. Ensure the machine is fully de-energized and the power source locked out before mounting or removing the wheel. Verify that the grinder's rated RPM meets or exceeds the wheel's maximum operating speed before use. Inspect the wheel for damage prior to each use and never operate a cracked or deformed unitized wheel.
