3M 7100033185 Cubitrona Ii 786F File Belt 60 Grit 18x0.5 in

Product Description

The 3M 7100033185 is a Cubitrona II 786F abrasive file belt engineered for demanding metal grinding and finishing applications. Built on a heavy-duty backing with a resin bond, it uses Precision Shaped Grain technology — a ceramic and aluminum oxide blend with uniformly sized, vertically oriented grains — to deliver fast, consistent stock removal. The resin bond works alongside a grinding aid to keep the belt cutting cool and sharp throughout its service life. At 60 grit, this belt is well suited for aggressive material removal tasks where heat control and belt longevity are critical priorities for the technician.

This file belt is designed for use with the 3M File Belt Sander and is suited for tasks including grinding out rivets, removing spot welds, and working high-strength steel in fabrication or collision repair environments. Its cooler-running characteristics reduce the risk of metal discoloration, oxidation, and heat-related stress cracks — factors that matter when working on structural or finished metal components. The belt is sold in a box with a minimum quantity of 5 units.
