3M 7000120678 Scotch-brite Exl Unitized Wheel 4 in Fine Grit

Product Description

The 3M 7000120678 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing across a wide range of materials. Built with a soft, conformable construction, this 4-inch diameter wheel uses Silicon Carbide abrasive at a Fine grit rating to deliver consistent, controlled stock removal without smearing or excessive heat buildup. At 0.1 pounds, it is lightweight and suitable for both handheld and automated tooling setups. Fabricators, metalworkers, and finishing technicians use this wheel for edge work and surface prep on metal alloys, plastics, and composites.

This unitized wheel is suited for job-shop and production environments where consistent surface quality is required. Its layered, unitized construction allows operation in both clockwise and counterclockwise directions, making it adaptable to a range of bench grinders, die grinders, and robotic finishing systems. The conformable nature of the abrasive keeps it in contact with complex or irregular part profiles, which is particularly useful in automated or robotic processing cells where part geometry varies.

Key Features

• Silicon Carbide abrasive at Fine grit for controlled deburring and finishing
• Soft, conformable construction stays in contact with complex-shaped parts during robotic or manual processing
• Unitized layered design operates in clockwise or counterclockwise directions
• Resists smearing for cleaner surface results and reduced prep time
• Minimizes heat buildup, reducing risk of damage to heat-sensitive materials
• Wheel edge can be dressed for precision deburring, finishing, and polishing of metal alloys, plastics, and composites

Compatibility

Designed for use on metal alloys, plastics, and composites; compatible with bench grinders, die grinders, and robotic finishing equipment that accept 4-inch unitized wheels.

Installation Notes

Installation should be performed by a qualified technician following the tool manufacturer's maximum RPM rating for the wheel diameter. Power down and de-energize all equipment before mounting or removing the wheel. Verify arbor size and flange compatibility before operation. Always follow applicable ANSI B7.1 safety standards for abrasive wheel use and wear appropriate PPE including eye protection.
