3M 7010328734 Scotch-brite Unitized Wheel 4 in 3/8 in Arbor

Product Description

The 3M 7010328734 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 4-inch diameter wheel mounts on a 3/8-inch arbor and operates in either clockwise or counterclockwise direction. The high concentration of abrasive mineral cuts fast and delivers a bright, consistent finish from the first use through the full life of the wheel. It weighs 0.09 pounds and ships in minimum quantities of 20. Metalworking professionals and fabricators working with stainless steel, carbon steel, and high-nickel alloys are the primary users of this wheel.

This unitized wheel is well suited for applications requiring portability and access to tight areas where larger wheels cannot reach. Its small 4-inch diameter and narrow profile make it a practical starting point for jobs that demand both aggressive cutting action and controlled surface finishing. It performs reliably on deburring and blending operations across harder metal substrates in both shop and field environments where a right-angle grinder or similar power tool is used.

Key Features

• Tightly layered unitized construction runs in clockwise or counterclockwise rotation
• High abrasive mineral concentration delivers fast cutting and a bright finish throughout wheel life
• Flexible, non-woven construction controls abrasive action to help prevent undercutting or gouging
• Resists loading and wears at a uniform rate for continuous cutting action
• 4-inch diameter and 3/8-inch arbor support portable tool use in confined or field applications
• Suited for stainless steel, carbon steel, and high-nickel alloys

Compatibility

Designed for use on right-angle grinders and die grinders fitted with a 3/8-inch arbor. Suitable for metalworking applications on harder metals including stainless steel, carbon steel, and high-nickel alloys.

Installation Notes

Installation should be performed by a qualified metalworking professional or machinist familiar with abrasive wheel mounting procedures. Verify that the tool spindle speed does not exceed the maximum rated RPM of the wheel before operation. Ensure the grinder is powered off and unplugged before mounting or removing the wheel. Inspect the wheel for damage prior to each use and confirm the arbor nut is properly secured.
