Offered in very narrow widths for use on tight radii and hard-to-reach applications. Flexible yet extra durable splice method for resistance to breaking or cracking under severe stress.

Brown coarse belts are excellent for deburring and blending, and creating a smooth transition on surface profiles from mill or tool marks.
