3M 7100042694 Scotch-brite Exl Unitized Wheel 2 in Ao

Product Description

The 3M 7100042694 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing operations on metal alloys, plastics, and composites. The wheel measures 2 inches in diameter with a 1/8 inch arbor and uses aluminum oxide (AO) abrasive mineral. Its soft, conformable construction keeps the abrasive in consistent contact with workpiece surfaces, making it well suited for edge work and light surface conditioning. The layered, unitized structure resists smearing and minimizes heat build-up, which is critical when working with heat-sensitive materials.

This wheel is used in fabrication, metalworking, and light manufacturing environments where controlled surface finishing is required. It handles deburring and edge finishing on machined parts, welded assemblies, and formed components made from steel, aluminum, and non-ferrous alloys, as well as select plastics and composite materials. The wheel can operate in both clockwise and counterclockwise directions, making it compatible with a range of bench-mounted or handheld rotary tools and robotic processing setups.

Key Features

• Aluminum oxide abrasive provides consistent cut on metal alloys, plastics, and composites
• Soft, conformable consistency maintains abrasive contact on complex or irregular part geometries
• Unitized, layered construction operates in clockwise or counterclockwise rotation
• Resists smearing for cleaner surface results and reduced prep time
• Minimizes heat build-up to protect heat-sensitive substrates
• Wheel edge can be dressed for deburring, finishing, and polishing applications

Compatibility

Designed for use with rotary tools, bench grinders, and automated robotic finishing systems accepting a 1/8 inch arbor and accommodating a 2 inch diameter wheel.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel mounting procedures. Confirm the tool spindle speed rating meets or exceeds the maximum RPM rating of the wheel before mounting. Inspect the wheel for damage before each use and ensure the arbor nut is properly secured before operating. Always use appropriate eye and face protection when operating abrasive wheels.
