3M 7000120747 Scotch-brite Exl Unitized Wheel 12 Inch

Product Description

The 3M 7000120747 is a Scotch-Brite EXL Unitized Abrasive Wheel engineered for smoothing, deburring, and finishing operations on metal alloys, plastics, and composites. The wheel uses silicon carbide abrasive mineral bonded into a soft, conformable unitized construction that keeps consistent abrasive contact across complex part geometries. At 12 inches in diameter and 1.69 inches wide, it is sized for bench-mounted or pedestal grinding setups used in fabrication, metalworking, and finishing shops. The layered, non-woven structure resists smearing and minimizes heat buildup, making it suitable for use on heat-sensitive base materials.

This wheel is applied in deburring, surface finishing, and edge blending operations across a range of industries including metal fabrication, aerospace component prep, and plastics manufacturing. It performs in both manual and automated robotic processing environments due to its consistent conformability across irregular and complex part surfaces. The wheel accepts both clockwise and counterclockwise spindle rotation, which simplifies setup on existing equipment. Minimum order quantity is 2 units per the supplier specification.

Key Features

• Silicon carbide abrasive for effective cut on metal alloys, plastics, and composites
• Soft, conformable unitized construction maintains abrasive contact on complex or irregular part shapes
• Bidirectional rotation — operates clockwise or counterclockwise without performance loss
• Minimizes heat buildup to protect heat-sensitive workpiece materials
• Resists smearing for cleaner finished surfaces and reduced prep time
• Wheel edge can be dressed to restore cutting performance and extend usable life

Compatibility

Designed for use on bench grinders, pedestal grinders, and automated robotic finishing equipment accepting a 12-inch diameter unitized wheel. Suitable for finishing and deburring operations on metal alloys, many plastics, and composites.

Installation Notes

Unitized abrasive wheels of this diameter are typically mounted by metalworking or finishing technicians following the grinder manufacturer's arbor and flange specifications. Power down and lock out the grinder before mounting or removing the wheel. Verify spindle speed rating of the machine does not exceed the maximum RPM rating of the wheel before operation. Inspect the wheel for damage before each use and replace if any cracking or delamination is observed.
