3M 7000000708 Scotch-brite Exl Unitized Wheel 8 in Fine Grit

Product Description

The 3M 7000000708 is a Scotch-Brite EXL Unitized Wheel designed for deburring, smoothing, and surface finishing across a wide range of materials. Built with a layered, unitized construction and charged with silicon carbide abrasive at a fine grit rating, this wheel delivers consistent, controlled material removal without smearing or excessive heat buildup. At 8 inches in diameter, it suits bench grinder and automated robotic processing setups commonly used in metal fabrication, manufacturing, and finishing shops. Machinists, fabricators, and surface finishing technicians are the primary users of this wheel.

This wheel is suited for finishing and deburring the edges and surfaces of metal alloys, plastics, and composites. Its soft, conformable construction allows the abrasive to maintain contact with complex contours and irregular part geometries, making it a practical choice for both manual bench operations and robotic processing cells. The fine grit designation targets light deburring, edge blending, and pre-polish surface prep rather than aggressive stock removal.

Key Features

• Silicon carbide abrasive construction delivers fine grit cutting action on metal alloys, plastics, and composites
• Soft, conformable consistency allows the wheel to follow complex part geometries and contoured edges
• Layered unitized construction supports operation in both clockwise and counterclockwise directions
• Resists smearing for cleaner finished surfaces and reduced post-process preparation
• Minimizes heat buildup, reducing thermal impact on heat-sensitive base materials
• Wheel edge can be dressed to maintain effective deburring and finishing performance

Compatibility

Designed for use on bench grinders and automated or robotic finishing equipment that accept 8 inch diameter unitized abrasive wheels. Suitable for finishing and deburring metal alloys, plastics, and composites.

Installation Notes

Installation should be performed by a qualified machinist or equipment operator following the machine manufacturer's mounting specifications. Power down and lockout the grinder or finishing equipment before mounting or removing the wheel. Verify the machine's maximum RPM rating is compatible with the wheel's rated speed before operation. Inspect the wheel for damage prior to each use and do not use a wheel that shows signs of cracking or uneven wear.
