13 Piece High Speed Steel Drill Bit Sets

Premium high speed steel with a duotone finish for fast chip removal in wood, soft metal, plastic, and plaster.
No center punch needed: 135° points are self-centering and penetrate faster with less pressure.
Ground flats on the shank provide tight chucking, even with keyless chucks. Flats are ground on drills 3/16" and up.
