Dormer R510 3.90MM CDX Carbide Straight Shank Jobber Drill TiN Coated

Jobber length drill bit has a midrange drilling depth of 4 times its diameter for general-purpose applications Solid carbide drills produce close-tolerance holes in hard materials, and have a longer tool life at higher speeds than cobalt and high-speed steel (HSS) Titanium nitride (TiN) coating offers increased wear resistance, extended tool life, and higher hardness on ferrous and nonmetallic materials Self-centering 130-degree split point penetrates hard material without a pilot hole and produces small chips to reduce clogging Drill bit conforms to DIN 338 standard
