3M 7000045850 Scotch-brite Unitized Wheel 2 in 1/4 in Arbor

Product Description

The 3M 7000045850 is a Scotch-Brite Cut and Polish Unitized Wheel designed for aggressive deburring, blending, and finishing on harder metals. Built with a tightly layered, non-woven construction, this 2-inch diameter wheel mounts on a 1/4-inch arbor and operates in both clockwise and counterclockwise directions. It carries a high concentration of aluminum oxide abrasive mineral that cuts fast and consistently produces a bright finish from first use through the end of the wheel's life. Medium to hard density options make it well suited to demanding surface conditioning tasks where control and portability are required.

This unitized wheel is intended for use on stainless steel, carbon steel, high nickel alloys, and other harder metals. Its small 2-inch diameter and narrow width make it practical for portable tool applications and tight-access finishing work. Fabricators, metalworkers, and maintenance technicians rely on this wheel for blending welds, removing burrs, and achieving consistent surface finishes without undercutting or gouging the base material. The non-woven Scotch-Brite construction resists loading, so the wheel continues cutting cleanly throughout its service life.

Key Features

• Tightly layered unitized construction supports clockwise and counterclockwise operation
• High concentration of aluminum oxide mineral delivers fast, consistent cutting action
• Flexible, non-woven design provides controlled abrasive action and helps prevent undercutting or gouging
• Resists loading and wears at a uniform rate for continuous performance across the wheel's life
• Small 2-inch diameter and narrow width suit portable tool use and restricted-access applications
• Effective on stainless steel, carbon steel, and high nickel alloys

Compatibility

Designed for use with portable rotary tools and right-angle grinders equipped with a 1/4-inch arbor. Suitable for surface conditioning, deburring, blending, and finishing on harder metals including stainless steel, carbon steel, and high nickel alloys.

Installation Notes

Mounting and operation should be performed by qualified personnel familiar with abrasive wheel safety practices. Confirm the tool spindle speed does not exceed the maximum rated RPM marked on the wheel or its packaging before mounting. Secure the arbor nut firmly and inspect the wheel for damage before each use. Always wear appropriate eye and face protection when operating abrasive wheels.
