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.

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

The shank has a smaller diameter than the tip, allowing you to drill large holes with machines that have small-capacity chucks. Also known as Silver and Deming bits, they have a 1/2” diameter shank.
Drill bits with flats on shank have three flat sides to prevent the bit from slipping in the drill chuck.
Drill bits with a split point keep centered without a pilot hole.
