6-Piece Step Drill Bit and Automatic Center Punch Set with Tough Case Small

Double Slot & Triple Shank: The split point tip is 118 degrees to increase wear resistance. The dual-fluted design provides faster, smoother, accurate cuts and keeps metal shavings from flying around for added safety; the triple-flat shank fits securely into the power tool chuck, eliminating slippage
Automatic Center Punch: Delivers an automatic, high-impact, spring-loaded strike when pressed against a surface; adjustable cap regulates striking force
