3M 7010329450 Scotch-brite EX2 Convolute Deburring Wheel 8 in

Product Description

The 3M 7010329450 Scotch-Brite EX2 Deburring Wheel is a convolute-constructed abrasive wheel engineered for mid-range aggressiveness and hardness across a broad range of surface finishing tasks. Measuring 8 inches in diameter, this wheel handles deburring, edge radiusing, blending, polishing, and finishing on metal alloys, many plastics, and composites. The layered construction resists heat buildup, reducing the risk of thermal damage on heat-sensitive workpieces. Fabricators, machinists, and metalworking shops install this wheel on bench grinders and pedestal-mounted finishing machines where consistent, controlled surface preparation is required.

This wheel is suited for industrial and production shop environments where recurring deburring of sharp edges, flash removal, and surface blending are part of the daily workflow. It performs best when consistently presented with sharp metal edges or burrs, making it well matched for post-machining cleanup on ferrous and non-ferrous metals. Its convolute design supports use on aluminum, steel, stainless, and a range of engineered plastics. The wheel edge can be dressed to restore cutting geometry as the wheel wears, extending useful service life in high-volume finishing operations.

Key Features

• Convolute construction delivers mid-range aggressiveness for deburring, blending, and polishing
• Wheel edge is dressable for effective finishing across metal alloys, plastics, and composites
• Operates in clockwise or counterclockwise rotation for flexible machine mounting
• Minimizes heat buildup to protect heat-sensitive workpiece materials
• Resists smearing for cleaner surfaces and reduced prep time
• Layered, unitized construction maintains consistent hardness and density throughout service life

Compatibility

Designed for use on bench grinders and pedestal finishing machines that accept 8-inch diameter convolute deburring wheels. Suitable for use on metal alloys, many plastics, and composite materials.

Installation Notes

Installation should be performed by qualified shop personnel following the machine manufacturer's mounting instructions and applicable safety standards. Ensure the machine is fully de-energized and the spindle is at a complete stop before mounting or removing the wheel. Verify that the machine's maximum RPM rating meets or exceeds the wheel's rated speed before operation. Dress the wheel edge with an appropriate dressing tool before first use to expose fresh abrasive and establish proper cutting geometry.
