3M 7000046140 Scotch-brite Exl Unitized Wheel 3 in Ao

Product Description

The 3M 7000046140 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing operations on metal alloys, plastics, and composites. Built with aluminum oxide abrasive and a soft, conformable construction, this 3-inch diameter wheel mounts on a 3/8-inch arbor and delivers consistent surface contact across complex part geometries. Its unitized, layered design maintains a uniform cut rate throughout the wheel's life. Weighing 0.05 pounds, it is well-suited for bench grinder or die grinder use in fabrication and finishing workflows. Licensed trades and skilled metalworkers rely on this wheel for controlled deburring without smearing or excess heat generation.

This wheel fits applications in metal fabrication, light manufacturing, and maintenance repair operations. It is effective on ferrous and non-ferrous alloys as well as many plastics and composites. The conformable consistency makes it especially useful where edge geometry varies or where robotic processing requires consistent abrasive-to-part contact. Available in a range of densities and grades, the EXL line allows selection from very soft, conformable cuts to hard, aggressive stock removal depending on the application requirement.

Key Features

• Soft, conformable construction keeps abrasive in contact with irregular and complex-shaped part edges
• Unitized, layered build provides consistent cut rate and finish quality throughout wheel life
• Operates in both clockwise and counterclockwise directions for flexible setup
• Minimizes heat build-up, reducing risk of thermal damage to heat-sensitive materials
• Resists smearing for cleaner finished surfaces and reduced prep time
• Wheel edge can be dressed to restore profile for deburring, finishing, and polishing tasks

Compatibility

Designed as a replacement or production-run unitized finishing wheel for bench grinders, die grinders, and automated finishing equipment accepting a 3/8-inch arbor and accommodating a 3-inch diameter wheel.

Installation Notes

Installation and use should be performed by qualified metalworkers or maintenance technicians familiar with abrasive wheel safety. Always power down and de-energize the grinder before mounting or removing the wheel. Verify the grinder spindle speed rating meets or exceeds the wheel maximum RPM before operation. Use appropriate eye and face protection per applicable safety standards when operating abrasive wheels.
