Cobalt Adapter Drills
Drills are manufactured to NAS 965 Type .D' construction with 135° heavy duty split points and surface treated. Made from M42 8% cobalt high speed steel. Great for drilling hard, tough high tensile strength materials in confined areas. When drilling low tensile strength materials these drills will have a significantly greater tool life than standard H.S.S., resulting in a much lower cost per drill.

Note: Carbide drills, PCD drills, & custom drill sizes also available, please inquire.
