For tough, high tensile strength materials like stainless steel

135° split point tip prevents drill from walking

1/2 in. shank expands the size range capacity of drill chuck

Effective in drilling tough, high tensile strength materials like stainless steel, Inconel, and titanium

Display high red hardness, permitting speeds up to 30% greater than with conventional M2 high speed steel

Manufactured to National Aerospace standard 907

135° split point is self-centering and reduces thrust

All drills have 3 in. flute length and 6 in. overall length for minimal adjustment during tool changes

Expand the size range capacity of a portable drill chuck

Drill America D/ACO Cobalt Reduced Shank Drill Bit. D/ACO cobalt drill bits are made of heat resistant m42 cobalt. They are ground to a heavy-duty 135° split point. They are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys.
