Drill America 6-Piece 1/2-in x 6-in Cobalt Twist Drill Bit

Drill America DWDCO Cobalt Jobber length (standard length) drill bits. Drill America DWDCO M35 cobalt drills are manufactured to National Aerospace standard 907. These drill bits display high red hardness, permitting speeds up to 30% greater than with conventional M2 high speed steel and are especially effective in drilling tough, high tensile strength materials like stainless steel, Inconel and titanium. The 135 split point is self-centering and reduces thrust.
