High-Speed Steel 1/2" Diameter Reduced-Shank Drill Bit Sets
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, these bits have a 1/2" diameter shank.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than black-oxide drill bits.
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.
