3M 7000045937 Scotch-brite Exl Unitized Wheel 6 Inch

Product Description

The 3M 7000045937 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel uses aluminum oxide (AO) abrasive mineral bonded into a soft, conformable unitized construction that keeps abrasive material in consistent contact with the workpiece throughout the wheel's life. At 6 inches in diameter with a 1/2-inch arbor bore, this wheel mounts directly to bench grinders, pedestal grinders, and automated finishing equipment. It is well suited for precision edge work and surface preparation where heat control and surface cleanliness matter.

This wheel is used in metalworking, fabrication, and light manufacturing environments for deburring cut edges, blending weld seams, and pre-finishing surfaces before coating or inspection. The conformable structure makes it effective on contoured or complex-shaped parts, including those processed in robotic or automated workcells. It handles both ferrous and non-ferrous alloys as well as a range of engineered plastics and composites. Fabricators, machinists, and maintenance technicians are the primary users in both job shop and production settings.

Key Features

• Unitized construction maintains consistent cut rate and finish quality throughout wheel life
• Aluminum oxide abrasive mineral for use on metal alloys, plastics, and composites
• Conformable structure keeps abrasive in contact with complex or irregular part geometries
• Runs clockwise or counterclockwise, adding flexibility for machine setup
• Minimizes heat buildup, reducing risk of thermal damage to heat-sensitive base materials
• Resists smearing for cleaner cut surfaces and reduced prep time between operations

Compatibility

Designed for use on bench grinders, pedestal grinders, and automated finishing equipment accepting a 1/2-inch arbor and accommodating a 6-inch diameter wheel.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Power down and lock out the grinder before mounting or removing the wheel. Confirm the machine spindle speed does not exceed the maximum rated RPM marked on the wheel. Inspect the wheel for damage before each use and never operate a cracked or visibly damaged unitized wheel.
