10 High Speed Twist Drill Bits Great For Metal smiths, Metal Working & Drilling

Great for drilling ferrous metals, tough casting sand forgings, working hardened stainless steel and other hard steels and tough high tensile strength nonferrous metals like titanium

These will not lose their hardness with excessive heat build up

Each has a 1/16" shank
