Drill Bits
These jobbers'-length bits have the rigidity and length required for most applications.
Black-oxide and black-and-gold-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 oxide-coated 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.

Short-Flute Extended-Length Drill Bits
The short flutes on these bits provide increased rigidity for drilling straighter holes and the long length lets you access hard-to-reach spots.
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.

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.
