3M 7100188542 Scotch-brite Exl Unitized Wheel 6 in Ao

Product Description

The 3M 7100188542 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing metal alloys, plastics, and composites. The wheel uses an aluminum oxide (AO) abrasive mineral in a layered, unitized construction that maintains a soft, conformable consistency throughout its service life. At 6 inches in diameter with a 1/2 inch arbor, it mounts to bench grinders, angle grinders, and automated finishing equipment. The unitized structure minimizes heat buildup, which reduces thermal impact on heat-sensitive materials and helps produce cleaner surfaces with less follow-up preparation.

This wheel is suited for metalworking, fabrication, and finishing operations in industrial, manufacturing, and trade shop environments. It performs well on edge deburring, surface blending, and light polishing of ferrous and non-ferrous metals as well as many plastics and composites. The conformable construction makes it effective in robotic and automated processing lines where consistent abrasive contact with complex part geometries is required. It can operate in both clockwise and counterclockwise directions, offering flexibility in machine setup.

Key Features

• Layered unitized construction operates in both clockwise and counterclockwise directions
• Conformable consistency maintains abrasive contact on complex and irregular part shapes
• Aluminum oxide abrasive mineral for effective deburring, finishing, and polishing
• Minimizes heat buildup to protect heat-sensitive base materials
• Resists smearing for cleaner finished surfaces and reduced prep time
• Wheel edge can be dressed to maintain cutting performance over the wheel life

Compatibility

Designed for use on bench grinders, angle grinders, and automated finishing equipment accepting a 1/2 inch arbor and accommodating a 6 inch diameter wheel. Suitable for metal alloys, many plastics, and composite materials.

Installation Notes

Install on a grinder or finishing spindle rated for the wheel diameter and arbor size before powering the machine. Ensure the spindle RPM rating of the equipment does not exceed the maximum rated speed of the wheel. Wear appropriate eye protection and grinding PPE during use. Dress the wheel edge as needed using a standard wheel dresser to restore cutting geometry.
