3M 7000046170 Scotch-brite Exl Unitized Wheel 3 Inch Fine

Product Description

The 3M 7000046170 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing operations on metal alloys, plastics, and composites. Built with a soft, conformable construction and silicon carbide abrasive at a fine grit rating, this wheel stays in contact with irregular and complex part geometries throughout the finishing pass. The layered, unitized structure maintains consistent cut and surface quality across the life of the wheel. Machinists, fabricators, and finishing technicians use this wheel on bench grinders, die grinders, and automated robotic finishing systems where repeatable surface results are required.

This wheel is suited for light deburring, edge finishing, and pre-polish preparation on ferrous and non-ferrous metals as well as many plastics and composites. The fine grit designation makes it appropriate for finishing and polishing stages rather than heavy stock removal. Its conformable nature is particularly useful in robotic or automated processing cells where the abrasive must follow contoured or profiled part edges without operator adjustment. Manual bench and pedestal grinder applications are equally well served.

Key Features

• Silicon carbide abrasive provides consistent cut on metal alloys, plastics, and composites
• Fine grit rating suited for finishing, polishing, and light deburring passes
• Soft, conformable construction maintains abrasive contact on complex and contoured part geometries
• Layered unitized structure supports operation in both clockwise and counterclockwise directions
• Resists smearing for cleaner finished surfaces and reduced prep time between operations
• Minimizes heat build-up, reducing risk of damage to heat-sensitive materials

Compatibility

Designed as an OEM-style replacement unitized wheel for bench grinders, die grinders, and robotic finishing systems that accept 3 inch diameter unitized abrasive wheels.

Installation Notes

Installation should be performed by a qualified machinist or finishing technician familiar with abrasive wheel mounting requirements. Always power down and de-energize the grinder or spindle drive before mounting or removing the wheel. Verify that the spindle speed rating of the machine does not exceed the rated RPM of the wheel before operation. Follow applicable ANSI B7.1 abrasive wheel safety standards for mounting, guarding, and ring testing procedures.
