  • Cobalt Threaded Drill ATS-10-021 #21

    $0.00
    *MINIMUM ORDER OF 12 / CALL FOR PRICING*
    Type “D” adapter drills are made from cobalt high speed steel and are 
    manufactured to NAS 965 Type “D” specifications with 135° heavy duty 
    split points and surface treated for drilling hard, tough high tensile 
    strength materials. When drilling low tensile strength materials, the 
    Type “D” cobalt drill will have a significantly greater tool life than 
    the NAS 954 Type “B”, high speed steel adapter drill, resulting in a 
    much lower cost per drill.
