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.

Chip-Clearing Drill Bits
These jobbers'-length bits have the rigidity and length required for most applications. The flutes are designed to lift chips out of the hole, reducing clogging and improving coolant flow.
Parabolic spiral flute drill bits have wider flutes for more efficient chip evacuation than spiral-flute 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.
Titanium-aluminum-nitride (TiAlN) coated drill bits are the most wear and temperature resistant for the longest life and highest drilling speeds.
Drill bits with a split point keep centered without a pilot hole.

Smooth-Finish Carbide Drill Bits
Three cutting edges instead of the typical two enable these bits to drill holes with a smoother finish than other bits. 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. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling. All are jobbers’ length so they have the rigidity and length required for most applications. A split point keeps the bit centered without a pilot hole.

Short-Length Carbide-Tipped Drill Bits
Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than standard-length drill bits. 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.

Cobalt Steel Drill Bits for Stainless Steel and Nickel
Cobalt steel and a titanium aluminum nitride (TiAlN) coating provide the heat and wear resistance necessary for drilling in stainless steel and nickel alloys. These bits have parabolic spiral flutes, which lift chips out of the hole to reduce clogging and improve coolant flow. They are jobbers' length and have the rigidity and length required for most hand-held drilling and machine tool applications.
