Short-Length Drill Bits
Black Oxide
Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'- and maintenance-length drill bits.
Black-oxide drill bits produce less friction than uncoated drill bits.
Drill bits with a split point keep centered without a pilot hole.
