3M 7000120751 Unitized Abrasive Wheel 1.5 in Silicon Carbide

Product Description

The 3M 7000120751 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing metal alloys, plastics, and composites. The wheel measures 1.5 inches in diameter and uses silicon carbide as its abrasive mineral. Its soft, conformable construction keeps the abrasive in consistent contact with workpiece surfaces, reducing heat buildup and minimizing smearing. This type of wheel is typically used by metal fabricators, machinists, and finishing technicians working on production lines or bench grinder setups where surface quality and edge condition are critical to downstream processes.

This unitized wheel suits a broad range of finishing applications including deburring cut edges, blending weld seams, and surface preparation on metal alloys as well as select plastics and composites. The layered, unitized construction allows the wheel to run in either clockwise or counterclockwise rotation, providing flexibility for use on standard bench grinders, pedestal grinders, or robotic finishing cells where the wheel must conform to complex-shaped parts without aggressive stock removal.

Key Features

• Silicon carbide abrasive mineral suited for finishing metal alloys, plastics, and composites
• Soft, conformable consistency maintains abrasive contact on irregular and complex-shaped surfaces
• Unitized layered construction operates in clockwise or counterclockwise rotation
• Minimizes heat buildup to protect heat-sensitive workpiece materials
• Resists smearing for cleaner surface results and reduced prep time
• Wheel edge can be dressed for targeted deburring, finishing, and polishing work

Compatibility

Designed as an OEM-style replacement or direct-use unitized abrasive wheel for bench grinders and pedestal grinders accepting 1.5-inch diameter wheel accessories.

Installation Notes

Mounting should be performed by a qualified operator following the grinder manufacturer's arbor and flange specifications. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for damage before each use and confirm the grinder's rated RPM is compatible with the wheel's maximum operating speed. Eye protection and appropriate PPE are required during operation.
