3M 7010309500 Scotch-brite Exl Unitized Wheel 4 in Ao

Product Description

The 3M 7010309500 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel uses aluminum oxide (AO) abrasive mineral embedded in a soft, conformable, layered construction that keeps the abrasive in consistent contact with the workpiece. At 4 inches in diameter with a 5/8 inch arbor bore, this wheel mounts to bench grinders, die grinders, and automated finishing equipment. It weighs 0.08 pounds and ships as a single unit. The unitized construction resists smearing and minimizes heat buildup, making it well suited for heat-sensitive materials and precision finishing work.

This wheel is used in fabrication shops, machine shops, and light manufacturing environments where consistent edge finishing and deburring are required. It handles a broad range of materials including ferrous and non-ferrous metal alloys, many plastics, and composite materials. Its conformable construction makes it effective for complex-shaped parts and is compatible with robotic and automated processing setups. The wheel can rotate in either clockwise or counterclockwise direction, adding flexibility to a variety of finishing station configurations. Typical users include metal fabricators, machinists, and maintenance technicians performing surface prep and finishing tasks.

Key Features

• Soft, conformable unitized construction keeps abrasive in contact with complex or irregular part geometry
• Aluminum oxide (AO) abrasive mineral delivers consistent cut on metal alloys, plastics, and composites
• Operates clockwise or counterclockwise for flexible machine mounting
• Minimizes heat buildup to protect heat-sensitive workpiece materials
• Resists smearing for cleaner finished surfaces and reduced secondary prep
• Wheel edge can be dressed for targeted deburring, finishing, and polishing

Compatibility

Designed as a replacement or production-use unitized wheel for bench grinders, pedestal grinders, and automated finishing equipment accepting a 5/8 inch arbor and up to 4 inch diameter wheel.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with abrasive wheel safety. Power down and lock out the grinder or finishing machine before mounting the wheel. Verify that the machine spindle speed does not exceed the rated maximum RPM marked on the wheel or packaging. Inspect the wheel for damage before each use and confirm the arbor bore fits the spindle without forcing.
