3M 7000120836 Deburring Wheels Kit 30 Piece

Product Description

The 3M 7000120836 is a 30-piece deburring wheels kit designed for material finishing, edge deburring, and surface blending on metal, plastic, and composite workpieces. The kit includes unitized wheels in four diameters ranging from 1/2 inch to 2 inches, paired with two shank diameter options of 1/8 inch and 1/4 inch for compatibility with common rotary tools and die grinders. Abrasive materials include aluminum oxide and silicon carbide, and the kit spans fine, medium, and coarse grades to address a range of stock removal and finishing requirements. Machinists, fabricators, and maintenance technicians use this kit for deburring operations where a single assortment covers multiple wheel sizes and grades.

This kit is suited for bench-top rotary tools, portable die grinders, and drill press setups used in light fabrication, tool-and-die work, and general maintenance environments. The variety of wheel diameters and grades makes it practical for working on interior bores, slots, edges, and contoured surfaces where different wheel sizes are needed across a single job. The 1/8-inch and 1/4-inch shank options cover the most common collet sizes found in standard pneumatic and electric rotary tools used in industrial and shop settings.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians familiar with rotary abrasive tooling. Ensure the rotary tool or die grinder is powered off and disconnected from air or electrical supply before changing wheels. Verify that the selected shank diameter matches the collet or chuck of the tool before mounting. Follow the tool manufacturer's maximum RPM rating and do not exceed it with any wheel in this kit.
