This set of wire gauge drill bits is surface coated for fast chip ejection
These titanium high speed steel bits run cooler and last longer than standard drill bits. The titanium coating means they penetrate 75% faster, cut more freely so you use less power, and they don't expand with heat, so you get properly sized holes. The coating on the drill bit set is also thermal resistant to make them run cooler and execute your drilling with expert precision. The set comes organized in a metal indexed storage case for easy transport.
