3M 7010329210 Scotch-brite Exl Unitized Wheel 1.5 in Ao

Product Description

The 3M 7010329210 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for deburring, finishing, and polishing metal alloys, plastics, and composite materials. The wheel uses aluminum oxide (AO) abrasive mineral bonded into a soft, conformable, layered unitized construction. At 1.5 inches in diameter with a 0.188-inch arbor bore, this wheel mounts to bench grinders, die grinders, and automated rotary spindles. It weighs 0.01 pounds. Machinists, fabricators, and finishing technicians use this wheel where heat buildup and smearing must be minimized during surface prep and edge conditioning.

This wheel fits bench-top and inline rotary finishing applications across metal fabrication shops, machine shops, and production finishing lines. Its conformable consistency makes it especially effective on complex-shaped or contoured parts where rigid wheels lose contact. The EXL series spans multiple density and grade combinations, from soft 2-density wheels for maximum conformability to hard 8-density wheels for aggressive cut and long wheel life. This specific wheel is suited for light-duty deburring and finish work on edges and flat faces of ferrous and non-ferrous metals as well as select plastics and composites.

Key Features

• Aluminum oxide abrasive mineral for broad metal and plastic compatibility
• Unitized layered construction runs clockwise or counterclockwise without wheel degradation
• Conformable consistency maintains abrasive contact on complex and contoured part geometries
• Minimizes heat buildup, reducing risk of thermal damage to heat-sensitive base materials
• Resists smearing for cleaner finished surfaces and reduced prep time between operations
• Wheel edge can be dressed to restore cut and maintain consistent finishing performance

Compatibility

Designed as an OEM-style replacement or direct-use abrasive wheel for bench grinders, die grinders, and automated rotary finishing spindles accepting a 0.188-inch arbor and accommodating a 1.5-inch diameter wheel.

Installation Notes

Installation should be performed by a qualified machinist or finishing technician familiar with rotary abrasive tooling. Power down and lock out the spindle before mounting or removing the wheel. Confirm the spindle RPM rating does not exceed the wheel's rated maximum speed before operation. Inspect the wheel for damage before each use and do not use a wheel that shows cracking, delamination, or uneven wear.
