3M 7100188509 Scotch-brite Exl Unitized Wheel 3 in Ao

Product Description

The 3M 7100188509 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel uses an aluminum oxide abrasive in a soft, conformable construction that keeps the abrasive in continuous contact with the workpiece. This unitized design layers abrasive material throughout the wheel body, so performance remains consistent as the wheel wears. The 3-inch diameter and 1/4-inch arbor fit standard die grinders and bench-mounted spindles. Machinists, fabricators, and finishing technicians use this wheel for edge work and surface prep in both manual and robotic processing environments.

This wheel is suited for deburring and finishing operations on fabricated metal components, sheet metal edges, and machined parts where heat-sensitive materials or complex geometries require a controlled, low-heat abrasive action. The conformable construction makes it effective on irregular or contoured surfaces. It is used in both production shops and maintenance-repair environments where consistent surface finish quality is required on alloys, plastics, and composite materials.

Key Features

• Unitized, layered construction maintains consistent cut throughout the life of the wheel
• Operates in clockwise or counterclockwise rotation for flexible mounting configurations
• Conformable consistency keeps abrasive in contact with complex or contoured part geometries
• Aluminum oxide abrasive resists smearing for cleaner surfaces with less follow-up preparation
• Minimizes heat build-up, reducing risk of thermal damage to heat-sensitive materials
• Wheel edge can be dressed to restore profile for deburring, finishing, and polishing tasks

Compatibility

Designed for use on standard die grinders and spindle-mounted finishing equipment with a 1/4-inch arbor. Suitable for finishing and deburring applications on metal alloys, plastics, and composites.

Installation Notes

Mounting should be performed by a qualified operator familiar with abrasive wheel safety. Confirm the tool spindle speed does not exceed the maximum rated RPM of the wheel before mounting. Power down and disconnect the tool before installing or changing the wheel. Inspect the wheel for damage before each use and never force-mount a wheel onto an arbor that requires excessive pressure to seat.
