3M 7000046304 Scotch-brite Unitized Wheel 3 in 1/4 in Arbor

Product Description

The 3M 7000046304 is a Scotch-Brite Cut and Polish Unitized Wheel designed for aggressive deburring, blending, and finishing on harder metals. Its tightly layered, non-woven construction provides controlled abrasive action that resists loading and wears at a uniform rate, delivering consistent cut and finish throughout the wheel's life. The 3-inch diameter and 1/4-inch arbor make it well suited for portable tools, allowing technicians and fabricators to bring controlled finishing work directly to the part. This wheel is built for medium to hard density applications where undercutting or gouging cannot be tolerated.

This wheel is intended for metalworking and fabrication environments where surface prep on harder metals is required. Typical applications include deburring, edge blending, and finish work on stainless steel, carbon steel, and high nickel alloys. Its compact 3-inch diameter makes it practical in tight clearances and for jobs that require small-diameter tooling. It is commonly used in shops, maintenance facilities, and field service situations where a portable angle grinder or die grinder is the primary tool.

Key Features

• Tightly layered unitized construction operates in clockwise or counterclockwise rotation
• High concentration of aluminum oxide abrasive mineral delivers fast cutting and a bright finish throughout wheel life
• Flexible, non-woven construction provides controlled abrasive action that helps prevent undercutting and gouging
• Resists loading on harder metals including stainless steel, carbon steel, and high nickel alloys
• Compact 3-inch diameter and 1/4-inch arbor support use with portable die grinders and angle grinders

Compatibility

Designed for use with portable die grinders and right-angle grinders fitted with a 1/4-inch arbor. Suitable for deburring and finishing operations on harder metals including stainless steel, carbon steel, and high nickel alloys.

Installation Notes

Mount the wheel on a die grinder or angle grinder with a compatible 1/4-inch arbor before powering the tool. Verify that the tool's rated RPM does not exceed the maximum safe operating speed for this wheel diameter. Always wear appropriate eye and face protection during operation. Inspect the wheel for damage before each use and do not use a damaged or deformed wheel.
