3M 7010309359 Scotch-brite EX2 Deburring Wheel 8 Inch Fine

Product Description

The 3M 7010309359 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 finishing on metal alloys, plastics, and composites. The wheel measures 8 inches in diameter and weighs 3.9 pounds. Its layered, unitized construction maintains consistent cut and finish throughout the life of the wheel. Machinists, fabricators, and finishing technicians reach for this wheel when working with sharp edges or metal burrs that require controlled material removal without smearing or excessive heat buildup.

This wheel fits into bench grinder and pedestal grinder setups commonly found in metal fabrication shops, machine shops, and manufacturing environments. It is well suited for finishing stainless steel, aluminum, carbon steel, and many non-metallic materials including plastics and composites. The convolute construction allows the wheel edge to be dressed, keeping the working surface consistent across extended use cycles. It is appropriate for both production and maintenance finishing applications where surface quality and part integrity matter.

Key Features

• Convolute construction provides mid-range aggressiveness for controlled deburring and finishing
• Operates in both clockwise and counterclockwise directions for flexible machine compatibility
• Wheel edge can be dressed to maintain effective cut on metal alloys, plastics, and composites
• Resists smearing for cleaner finished surfaces with less prep work
• Minimizes heat buildup to protect heat-sensitive workpieces
• Fine grit grade suited for blending, polishing, and light material removal

Compatibility

Designed for use on bench grinders and pedestal grinders that accept convolute deburring wheels. Suitable for use on metal alloys and many plastics and composites.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel mounting procedures. Always power down and lock out the grinder before mounting or removing the wheel. Verify that the machine spindle speed does not exceed the maximum rated speed of the wheel before operation. Inspect the wheel for cracks or damage before each use and follow ANSI B7.1 safety standards for abrasive wheel use.
