Twister XL28 - 29 Piece mechanics length drill set

These bits are made in the USA. These bits have split point ends that allow them to drill steel faster than most without first drilling a pilot hole. This set is 29 pieces and starts at 1/16" and goes up to 1/2", graduations are 1/64". On the bits that are 3/16" and larger they have 3 flats ground on the shanks so that they can't spin in the drill chuck!!!
