3M 7000120837 Scotch-brite Exl Unitized Wheel 8 in

Product Description

The 3M 7000120837 is a Scotch-Brite EXL Unitized Abrasive Wheel engineered for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel measures 8 inches in diameter with a 1-inch arbor and features a soft, conformable construction that keeps the abrasive in consistent contact with irregular or complex part geometries. Built with aluminum oxide (AO) abrasive mineral, it delivers controlled cut while minimizing heat buildup — a critical advantage when working on heat-sensitive base materials. At 0.85 pounds, it is suited for use on stationary or robotic finishing equipment.

This wheel is used in metal fabrication, aerospace component finishing, and industrial deburring operations. Its unitized layered construction allows it to run in either clockwise or counterclockwise rotation, giving it flexibility across a range of bench grinder and finishing machine setups. The conformable density is well matched to applications where the abrasive must follow contoured or profiled workpiece edges without aggressive stock removal. Fabricators, machinists, and industrial maintenance technicians are the primary installers and operators of this wheel type.

Key Features

• Aluminum oxide abrasive mineral for effective deburring, finishing, and polishing of metal alloys, plastics, and composites
• Soft, conformable unitized construction maintains abrasive contact on complex and contoured part geometries
• Bidirectional rotation — operates clockwise or counterclockwise without performance loss
• Minimizes heat buildup, reducing thermal impact on heat-sensitive workpiece materials
• Resists smearing for cleaner surface results and reduced prep work between finishing steps
• Wheel edge can be dressed to restore cutting performance for deburring and polishing tasks

Compatibility

Designed for use on bench grinders, pedestal grinders, and robotic finishing equipment accepting an 8-inch diameter wheel with a 1-inch arbor bore.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician following the equipment manufacturer's mounting instructions. Verify that the machine's rated RPM does not exceed the maximum speed rating marked on the wheel before mounting. Disconnect and lock out power to the grinder before mounting or removing the wheel. Always install and use appropriate guards per applicable ANSI and OSHA safety standards for abrasive wheel equipment.
