Good To Know

Q: Should I use these files wet or dry? A: While they can be used dry, using a drop of water or light oil as a lubricant extends the life of the diamond coating and reduces airborne dust.

Q: Can these files be used on hardened metals? A: Yes, the industrial diamond coating is hard enough to file hardened steel, carbide, and titanium which regular steel files cannot cut.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
