3M 7000046078 Scotch-brite EX2 Deburring Wheel 8 Inch Fine

Product Description

The 3M 7000046078 is a convolute-constructed deburring wheel from the Scotch-Brite EX2 line, designed for mid-range aggressiveness and hardness in metalworking and finishing applications. The layered, convolute build delivers consistent performance for deburring, edge radiusing, blending, polishing, and finishing across a wide range of materials. At 8.7 inches in diameter and 4.2 inches wide, it mounts to bench grinders and pedestal finishing machines commonly found in fabrication shops and maintenance environments. The wheel weighs 1.37 pounds. Licensed machinists, tool-and-die technicians, metal fabricators, and maintenance mechanics are the primary installers and operators.

This wheel is suited for use on all metal alloys as well as many plastics and composites. It performs best when consistently presented with sharp edges or metal burrs, making it a practical choice for production deburring lines, job-shop finishing stations, and maintenance repair operations. Its mid-range density and fine grit grade position it between conformable soft wheels and hard aggressive wheels, covering a broad range of edge-finishing and surface-prep tasks on ferrous and non-ferrous metals alike.

Key Features

• Convolute, layered construction provides mid-range hardness and aggressiveness for deburring and finishing
• Operates in both clockwise and counterclockwise rotation directions
• Wheel edge can be dressed to maintain effective contact geometry for deburring, polishing, and finishing
• Resists smearing, resulting in cleaner finished surfaces and reduced secondary preparation
• Minimizes heat buildup during operation, reducing risk of thermal damage to heat-sensitive base materials
• Compatible with all metal alloys and many plastics and composites

Compatibility

Designed for use on bench grinders and pedestal finishing machines accepting convolute deburring wheels with an 8-inch nominal diameter. Suitable for ferrous metals, non-ferrous alloys, many plastics, and composites.

Installation Notes

Installation and operation should be performed by qualified machinists or maintenance mechanics familiar with abrasive wheel safety. Disconnect and lock out power to the finishing machine before mounting or removing the wheel, following OSHA 29 CFR 1910.215 abrasive wheel machinery standards. Inspect the wheel for visible damage before each use and verify that the machine spindle speed does not exceed the wheel's rated maximum RPM. Dress the wheel edge as needed using an appropriate dressing tool to maintain cutting efficiency.
