3M 7010309307 Scotch-brite Unitized Wheel 0.5 in Ao

Product Description

The 3M 7010309307 is a Scotch-Brite Cut and Polish Unitized Wheel designed for aggressive deburring, blending, and finishing on harder metals. The wheel measures 0.5 inches in diameter and features a 1/16 inch arbor, making it well suited for small-diameter applications where portability and access are priorities. Its tightly layered, non-woven construction uses aluminum oxide (AO) mineral at high concentration for fast cutting and consistent finish quality from first use to end of wheel life. Licensed trades and metalworking professionals reach for this wheel when working on stainless steel, carbon steel, and high nickel alloys.

This unitized wheel is used in deburring, edge blending, and surface finishing operations on harder metals in both shop and field settings. The small diameter and narrow width make it practical for portable tool applications and tight-access areas where larger wheels cannot reach. Its flexible, non-woven construction delivers controlled abrasive action that reduces the risk of undercutting or gouging the workpiece surface. The wheel is appropriate for use on stainless steel, carbon steel, and high nickel alloys.

Key Features

• High-concentration aluminum oxide mineral provides fast, consistent cutting action throughout wheel life
• Tightly layered, unitized construction supports clockwise and counterclockwise operation
• Flexible, non-woven build delivers controlled abrasion to help prevent undercutting or gouging
• Scotch-Brite material resists loading and wears at a uniform rate for continuous cutting performance
• Small 0.5 inch diameter and narrow width suit portable tool use and tight-access applications
• Medium to hard density options available for aggressive finishing and blending on harder metals

Compatibility

Designed for use on stainless steel, carbon steel, and high nickel alloys; suited for portable rotary tools and equipment accepting a 1/16 inch arbor in small-diameter wheel configurations.

Installation Notes

Installation and mounting should be performed by a qualified operator familiar with abrasive wheel safety practices. Ensure the tool spindle speed does not exceed the maximum rated RPM of the wheel before mounting. Power down and disconnect the tool from its power source before changing wheels. Inspect the wheel for damage before each use and follow applicable ANSI B11 abrasive wheel safety standards.
