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.

Access hard-to-reach spots and drill deep holes.

Black-oxide drill bits produce less friction than uncoated 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.

Titanium-aluminum-nitride (TiAlN) coated drill bits are the most wear and temperature resistant for the longest life and highest drilling speeds.

Gold-oxide drill bits produce less friction than uncoated drill bits.

Drill bits with a split point keep centered without a pilot hole.
