3M 7000045872 Scotch-brite Unitized Wheel 3 in 1/2 in Arbor

Product Description

The 3M 7000045872 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 wheel measures 3 inches in diameter and accepts a 1/2 inch arbor. It operates effectively in both clockwise and counterclockwise directions, making it a practical choice for portable angle grinder and die grinder setups used by fabricators, machinists, and finishing technicians. The high concentration of abrasive mineral delivers fast cutting action and maintains a consistent bright finish throughout the life of the wheel.

This unitized wheel is suited for use on stainless steel, carbon steel, and high nickel alloys in applications where controlled surface finishing is required. Its compact 3 inch diameter makes it well suited for tight access areas and jobs where small-diameter tooling is necessary. Typical applications include weld blending, edge deburring, and surface conditioning in fabrication shops, maintenance environments, and field service scenarios where portability is a priority.

Key Features

• Tightly layered unitized construction runs in clockwise or counterclockwise rotation
• High abrasive mineral concentration provides fast cutting and a consistent bright finish throughout wheel life
• Flexible non-woven construction delivers controlled abrasive action, reducing risk of undercutting or gouging
• Scotch-Brite material resists loading and wears uniformly for continuous cutting performance
• Available in medium to hard densities for use on harder metals including stainless steel and high nickel alloys
• Compact 3 inch diameter suits portable grinder applications and tight-access work areas

Compatibility

Designed for use with portable angle grinders and die grinders accepting a 1/2 inch arbor. Suitable for deburring, blending, and finishing operations on stainless steel, carbon steel, and high nickel alloys.

Installation Notes

This wheel is installed by a machinist or metal fabricator on a portable grinder or mounted grinder equipped with the appropriate 1/2 inch arbor. Disconnect and de-energize the tool before mounting or removing the wheel. Verify that the tool's rated RPM meets or exceeds the wheel's maximum operating speed before use. Inspect the wheel for damage before each use and follow applicable ANSI B7 safety standards for abrasive wheel mounting and operation.
