3M 7100066339 Surface Conditioning Belt 18x0.5 Inch Ao

Product Description

The 3M 7100066339 is a non-woven aluminum oxide surface conditioning belt designed for one-step preparation of workpieces before final finishes and coatings are applied. Measuring 18 inches in length and 0.5 inches in width, this belt is built with enhanced edge durability and flexibility to handle repeated use without rapid breakdown. The aluminum oxide abrasive on RC-grade non-woven material delivers good initial cut rate as well as extended cut rate over the life of the belt. It is used by fabricators, metalworkers, and finishing technicians working on composites and softer metals where efficient material prep is required.

This belt is well suited for flat surface work across a range of light metalworking and finishing applications. Tasks include deburring, blending, cleaning, coating removal, and surface finishing. It is particularly effective as a starting point when finishing stainless steel to a No. 4 finish. The belt performs best under average pressure and on flat surfaces, making it a practical general-use option in fabrication shops, maintenance environments, and production finishing lines.
