3M 7010309481 Scotch-brite Exl Unitized Wheel 14 Inch

Product Description

The 3M 7010309481 is a Scotch-Brite EXL unitized abrasive wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. Built with aluminum oxide (AO) abrasive in a layered, unitized construction, the wheel measures 14 inches in diameter with a 1.25-inch arbor bore. At 1.8 pounds, it is suited for bench-mounted or pedestal grinder setups used in fabrication, maintenance, and finishing operations. The conformable construction keeps the abrasive in continuous contact with the workpiece surface, which is especially useful on contoured or complex-shaped parts. Licensed trades and skilled fabricators rely on this wheel for consistent edge work without excessive heat transfer to the base material.

This wheel is applicable across light metal fabrication shops, maintenance and repair operations (MRO), and production finishing lines. It is well suited for work on steel, aluminum, stainless, and non-ferrous alloys, as well as many plastics and composites. The 14-inch diameter and 1.25-inch arbor sizing are common configurations for industrial bench grinders and pedestal units. It operates effectively in both clockwise and counterclockwise rotation, giving installers flexibility in machine orientation and setup.

Key Features

• Layered unitized construction operates in clockwise or counterclockwise rotation
• Conformable abrasive matrix maintains contact on complex and contoured part geometries
• Minimizes heat build-up, reducing thermal impact on heat-sensitive materials
• Resists smearing for cleaner cut surfaces and reduced prep time between operations
• Wheel edge can be dressed for deburring, finishing, and polishing across metals and plastics
• Available in multiple densities and grades from soft and conformable to hard and aggressive

Compatibility

Designed for use on bench grinders and pedestal units accepting a 1.25-inch arbor bore and accommodating a 14-inch diameter wheel. Suitable for processing metal alloys, plastics, and composite materials.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 standards. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and confirm the machine's rated RPM meets or exceeds the wheel's maximum operating speed. Ensure flanges, blotters, and arbor hardware are clean and properly seated before starting the machine.
