3M 7000120761 Scotch-brite Exl Unitized Wheel 3 in Ao

Product Description

The 3M 7000120761 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing operations on metal alloys, plastics, and composites. Built with a soft, conformable construction, the wheel maintains consistent abrasive contact across complex part geometries. The aluminum oxide (AO) abrasive media provides reliable cut while minimizing heat buildup, making it a practical choice for heat-sensitive workpieces. At 3 inches in diameter with a 3/8 inch arbor, this wheel mounts directly to bench grinders, die grinders, and finishing machines used in fabrication and maintenance shops.

This unitized wheel suits a wide range of surface finishing tasks in metal fabrication, manufacturing, and industrial maintenance environments. It is well suited for deburring cut edges, blending welds, and preparing surfaces prior to coating or inspection. The conformable structure makes it particularly effective in robotic or automated finishing cells where consistent contact pressure is critical. Machinists, fabricators, and maintenance technicians are the primary users of this type of tooling.

Key Features

• Soft, conformable unitized construction maintains abrasive contact on complex and contoured surfaces
• Operates in both clockwise and counterclockwise directions for flexible mounting
• Aluminum oxide abrasive smooths, deburrs, and finishes metal alloys, plastics, and composites
• 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 restore cut and extend service life

Compatibility

Designed as an OEM-style replacement unitized finishing wheel compatible with standard 3/8 inch arbor bench grinders, die grinders, and automated finishing equipment used in metal fabrication and industrial maintenance applications.

Installation Notes

Installation should be performed by a qualified fabricator or maintenance technician. Disconnect and lock out all power to the grinder or finishing machine before mounting or removing the wheel. Verify that the machine arbor size matches the 3/8 inch bore and that the spindle speed does not exceed the wheel's rated RPM before operation. Inspect the wheel for damage before each use and discard any wheel showing cracks, tears, or deformation.
