14-Piece HSS Twist Drill Bit Set with 135° Split Points, Black-Gold Coating and 3-Flat Shanks for Mixed Materials
14-Piece HSS Twist Drill Bit Set with 135° Split Points, Black-Gold Coating and 3-Flat Shanks for Mixed Materials
A 14-piece HSS twist drill bit set covers everyday holes in compatible metal, steel, wood and plastic with durable cutting geometry. Each 135-degree split point starts on contact to reduce walking, while the tapered web resists breakage when the job moves from light material to tougher stock.
Black-and-gold coating helps protect the high-speed-steel surface from rust and wear, and size markings on each shank make the required bit easier to identify. Larger sizes above 3/16 inch use three flats to reduce spinning in the chuck. The complete DWA1184 selection stores together in its case for fast setup at the bench or jobsite.
