3M 7010309508 Scotch-brite Unitized Wheel 8 in Ao

Product Description

The 3M 7010309508 is a Scotch-Brite unitized abrasive wheel engineered for deburring and surface finishing on demanding alloys. Built with a layered, unitized construction, the wheel is softer and more conformable than higher-density convolute wheels, making it well-suited for stainless steel, titanium, and other hard-to-finish materials. The wheel measures 8 inches in diameter with a 3/4 inch arbor bore and uses aluminum oxide (AO) as the abrasive mineral. At 1.5 pounds, it is light enough to run on portable equipment without excessive spindle load.

This wheel is designed for precision deburring, blending, and finishing tasks in metalworking environments. Its unitized construction allows for smaller diameters and narrower widths than convolute wheels, making it appropriate for intricate contours and tight geometries. Typical applications include finishing weld seams, edge deburring on fabricated parts, and surface conditioning on alloy components. It is commonly used in metal fabrication shops, aerospace maintenance facilities, and industrial manufacturing environments by machinists and metalworking technicians.

Key Features

• Layered unitized construction runs clockwise or counterclockwise without performance loss
• Resists loading and runs cool, extending wheel service life on continuous operations
• Conformable construction maintains consistent contact on intricate shapes and contours
• Compatible with smaller bench grinders and portable angle grinders
• Suited for demanding alloys including stainless steel and titanium

Compatibility

Designed as an OEM-style replacement or direct-fit abrasive wheel for bench grinders, pedestal grinders, and portable equipment accepting a 3/4 inch arbor and an 8 inch diameter wheel.

Installation Notes

Installation should be performed by a qualified machinist or metalworking technician familiar with abrasive wheel safety per ANSI B7.1 standards. Always power down and disconnect the grinder before mounting the wheel. Inspect the wheel for cracks or chips before installation and verify that the machine's maximum RPM rating meets or exceeds the wheel's rated speed. Use appropriate flanges and blotters as specified by the equipment manufacturer.
