3M 7010309612 Scotch-brite Unitized Wheel 8 in

Product Description

The 3M 7010309612 is a Scotch-Brite Cut and Polish Unitized Wheel designed for aggressive material removal and surface finishing on harder metals. Built with a tightly layered, non-woven abrasive construction, this wheel handles deburring, blending, and finishing tasks where consistent cut rate and finish quality are required throughout the wheel's life. The 8-inch diameter and 3/4-inch arbor size make it compatible with common bench and pedestal grinder setups. Aluminum oxide (AO) mineral at high concentration delivers fast cutting action while maintaining a bright surface finish. Medium to hard density construction suits applications on stainless steel, carbon steel, and high nickel alloys.

This unitized wheel is suited for metal fabrication shops, maintenance facilities, and field service applications where portability and consistent performance on harder metals are priorities. The narrow width and small-diameter availability make it a practical starting point for jobs requiring precision blending and finishing in tight or detailed areas. It is well-suited for trades working with structural steel, stainless components, and high-alloy parts that demand controlled material removal without gouging the base surface.

Key Features

• High concentration of aluminum oxide abrasive mineral delivers fast, consistent cutting action from start to finish
• Tightly layered unitized construction operates in clockwise or counterclockwise rotation
• Flexible, non-woven design provides controlled abrasive action that resists undercutting and gouging
• Scotch-Brite material resists loading and wears at a uniform rate for continuous cutting performance
• Medium to hard density supports aggressive deburring and blending on stainless steel, carbon steel, and high nickel alloys
• 8-inch diameter with 3/4-inch arbor fits standard bench grinder configurations

Compatibility

Designed for use on bench grinders and pedestal grinders accepting a 3/4-inch arbor with an 8-inch wheel diameter. Suitable for harder metals including stainless steel, carbon steel, and high nickel alloys.

Installation Notes

Installation and wheel changes should be performed by qualified personnel following the grinder manufacturer's instructions and applicable ANSI B7.1 safety standards for abrasive wheels. Always power down and disconnect the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before installation and confirm the machine's rated RPM does not exceed the wheel's maximum operating speed. Use the correct flanges and arbor hardware as specified by the grinder manufacturer.
