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.

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-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.

Cobalt Steel Morse Taper-Shank Drill Bits
With better heat and wear resistance than high-speed steel, these cobalt steel bits can run up to 25% faster and have a longer tool life. Install the Morse taper shank directly into the tapered spindle on machines such as drill presses and lathes. A split point keeps the bit centered without a pilot hole.
