3M 7000046079 Scotch-brite Exl Unitized Wheel 3 in Ao

Product Description

The 3M 7000046079 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. Constructed with a soft, conformable layered build, the wheel maintains consistent abrasive contact across irregular and complex part geometries. At 3 inches in diameter with a 3/8 inch arbor bore, it mounts directly to bench grinders, die grinders, and automated finishing equipment. The aluminum oxide abrasive construction delivers controlled cut and finish without generating excessive heat, making it suitable for heat-sensitive base materials.

This unitized wheel is used in metal fabrication, sheet metal finishing, and light manufacturing environments where consistent edge deburring and surface conditioning are required. It is well suited for both manual bench operations and robotic or automated processing lines. Typical applications include finishing welds, cleaning burrs from cut edges, and preparing surfaces on stainless steel, aluminum, and other metal alloys, as well as select plastics and composites.

Key Features

• Soft, conformable construction keeps abrasive in contact with complex or contoured part shapes
• Layered unitized build supports operation in both clockwise and counterclockwise directions
• Minimizes heat buildup to protect heat-sensitive materials during finishing
• Resists smearing for cleaner finished surfaces and reduced prep time
• Wheel edge can be dressed for precise deburring, finishing, and polishing
• Suitable for metal alloys, many plastics, and composites

Compatibility

Designed as a unitized abrasive wheel for use on bench grinders, die grinders, and automated finishing equipment accepting a 3/8 inch arbor and accommodating a 3 inch diameter wheel.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 guidelines. Power down and lock out the grinder or spindle before mounting or removing the wheel. Confirm that the machine spindle speed does not exceed the maximum rated RPM of the wheel before operation. Inspect the wheel for damage before each use and do not operate a cracked or compromised wheel.
