Innovative Products of America (IPA; Woodstock, NY) introduces the 8 in. Premium, Industrial Diamond File Set (#8108). Diamond files cut 10X faster, smoother and cleaner for a better finish than conventional files, says IPA, and they can cut into welds and hardened surfaces that other files can't. The #8108 files have a 12” overall length with an 8” blade, and come in a custom folding pouch. The #8108 Diamond File Set contains four files (Half Round, Flat, Square and Round) with an abrasive diamond coating that is harder than traditional files and usable in any direction.
