About This Product
Drill America D/ACO Cobalt Jobbber Length (Standard Length) drill bits. Drill America D/ACO 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.
