3M 7000148251 Scotch-brite Exl Unitized Wheel 2 in 1/4 in Arbor

Product Description

The 3M 7000148251 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing the edges of metal alloys, plastics, and composites. Its soft, conformable construction allows the abrasive material to maintain consistent contact with irregular and complex-shaped workpieces throughout the finishing process. The wheel measures 2 inches in diameter and mounts on a 1/4 inch arbor, making it well-suited for use with die grinders, bench grinders, and similar rotary tools. Licensed tradespeople and precision fabricators working with ferrous and non-ferrous metals, plastics, and composite materials will find this wheel a practical choice for controlled surface finishing.

This unitized wheel is used in light industrial, fabrication, and maintenance environments where consistent edge finishing and deburring are required. It is appropriate for both manual bench operations and automated or robotic processing setups due to its conformable construction. Typical applications include finishing cut edges, removing burrs from drilled or stamped parts, and preparing surfaces on metal alloys, plastics, and composites prior to further processing or coating.

Key Features

• Soft, conformable construction maintains abrasive contact on complex and irregular part geometries
• Tough, layered, unitized build allows operation in both clockwise and counterclockwise directions
• Resists smearing, producing cleaner surfaces with less prep work required
• Minimizes heat buildup to reduce thermal impact on heat-sensitive materials
• Wheel edge can be dressed for deburring, finishing, and polishing across a range of metal alloys, plastics, and composites
• Suitable for robotic and automated processing as well as manual operation

Compatibility

Designed as a replacement-style unitized finishing wheel for die grinders, bench grinders, and rotary tools accepting a 1/4 inch arbor. Suitable for use on metal alloys, many plastics, and composite materials.

Installation Notes

Installation is typically performed by a machinist, fabricator, or maintenance technician. Power down and disconnect the tool from its power source before mounting or removing the wheel. Confirm the tool spindle speed does not exceed the rated maximum RPM of the wheel before operation. Inspect the wheel for damage before each use and do not use on a tool with a damaged or worn arbor.
