Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'- and maintenance-length 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.

Holes in these bits allow coolant to be run through the tool for more efficient chip evacuation. Use them in CNC machines with coolant-through technology. 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. A titanium aluminum nitride (TiAlN) coating gives them additional wear and temperature resistance. 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.

Jobbers'-length drill bits have the rigidity and length required for most applications.

These jobbers'-length bits have the rigidity and length required for most applications. Made of carbide-tipped steel, which has better wear resistance than high-speed steel and cobalt steel, they maintain a sharper, harder edge at high temperatures for excellent performance on abrasive material, such as plastic. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill.

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

Drill bits with 135° point angle produce smaller chips than 118° point to prevent clogging.
