3M 7010329592 Scotch-brite Exl Unitized Wheel 1.5 in Ao

Product Description

The 3M 7010329592 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel measures 1.5 inches in diameter and mounts on a 0.125-inch arbor. Its layered, unitized construction uses aluminum oxide abrasive bonded through the full depth of the wheel, so performance remains consistent as the wheel wears. Machinists, fabricators, and toolroom technicians use these wheels in bench-mounted or handheld rotary applications where controlled, repeatable surface conditioning is required.

This wheel fits standard rotary tool setups and is suited for deburring cut edges, blending welds, and light finishing on ferrous and non-ferrous metals. The soft, conformable structure allows the abrasive to follow complex contours and irregular part geometry without loading or smearing the workpiece surface. It is also used on many engineering plastics and composite materials where heat buildup from aggressive abrasives would otherwise cause surface damage. The design supports both clockwise and counterclockwise spindle rotation, making it compatible with a wide range of rotary tools and automated fixtures.

Key Features

• Unitized layered construction delivers consistent cut throughout the full wheel life
• Aluminum oxide abrasive effectively deburrs, finishes, and polishes metal alloys, plastics, and composites
• Conformable structure maintains abrasive contact on irregular and complex-shaped parts
• Resists smearing for cleaner surfaces and reduced prep time between operations
• Minimizes heat buildup, reducing thermal impact on heat-sensitive workpiece materials
• Bidirectional rotation — runs clockwise or counterclockwise without repositioning

Compatibility

Designed as an OEM-style replacement or direct-fit abrasive wheel for standard rotary tools and bench grinders accepting a 0.125-inch arbor bore.

Installation Notes

Installation is performed by machinists or fabricators familiar with rotary abrasive tooling. Ensure the spindle is fully stopped and power is disconnected before mounting or removing the wheel. Confirm the tool spindle speed rating does not exceed the maximum rated RPM of the wheel before operation. Inspect the wheel for damage before each use and discard any wheel showing signs of delamination or cracking.
