Short-Length Drill Bits
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.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated and black-oxide drill bits.
Drill bits with a split point keep centered without a pilot hole.

Cobalt Steel Drill Bits
These jobbers'-length bits have the rigidity and length required for most applications. Made of cobalt steel, which has better heat and wear resistance than high-speed steel, they can run up to 25% faster and have a longer tool life.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits.
Drill bits with a split point keep centered without a pilot hole.

Carbide Drill Bits
These jobbers'-length bits have the rigidity and length required for most applications. Made of solid carbide for the highest accuracy and longest tool life, they are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits. They retain a sharp, hard edge at high temperatures for the best performance on hard and abrasive material. The four-facet point keeps the bit centered without a pilot hole. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.
