Extended-Length Drill Bits
Black Oxide
Black-oxide drill bits produce less friction than uncoated drill bits.

Cobalt Steel Drill Bits
Titanium Aluminum Nitride (TiAlN) Coated
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-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.
