3M 7010309825 Scotch-brite EX2 Convolute Deburring Wheel 8 in

Product Description

The 3M 7010309825 is a convolute-constructed deburring wheel from the Scotch-Brite EX2 line, designed for mid-range aggressiveness and hardness across a wide range of surface finishing tasks. It handles deburring, edge radiusing, blending, polishing, and final finishing in one abrasive wheel format. The wheel measures 8 inches in diameter and weighs 2.58 pounds. It is built for use on stationary bench or pedestal grinders in metal fabrication and light manufacturing environments. Fabricators, machinists, and finishing technicians working with metal alloys, plastics, and composites install and operate this wheel as part of standard part deburring and surface prep workflows.

This wheel fits into production and job-shop environments where consistent edge conditioning is required after cutting, stamping, or machining operations. The convolute layered construction performs best when the wheel edge is presented with a sharp burr or raw cut edge. It is suited for metal alloys including steel, stainless, aluminum, and brass, as well as many plastics and composite materials. The wheel can run in either clockwise or counterclockwise rotation, making it adaptable to most bench grinder configurations without repositioning.

Key Features

• Convolute layered construction delivers mid-range aggressiveness for deburring, edge radiusing, blending, and polishing
• Runs clockwise or counterclockwise for flexible grinder compatibility
• Wheel edge can be dressed to restore cutting performance on metals, plastics, and composites
• Resists smearing for cleaner finished surfaces and reduced prep time
• Minimizes heat buildup to protect heat-sensitive base materials
• 8 inch diameter suits standard bench and pedestal grinder arbors

Compatibility

Designed for use on bench grinders and pedestal grinders that accept convolute deburring wheels. Suitable for deburring and finishing operations on metal alloys, plastics, and composite materials. Verify arbor bore size and grinder RPM rating before mounting.

Installation Notes

A qualified machinist or fabricator should mount this wheel following the grinder manufacturer's instructions and applicable ANSI B11 or OSHA 1910.215 grinder safety standards. Disconnect and lock out power to the grinder before installing or removing the wheel. Inspect the wheel for damage before mounting and perform a free-spin test at operating speed before presenting workpieces. Never exceed the maximum RPM rating marked on the wheel or grinder.
