The Astro Pneumatic ONYX 29-Piece TurboStep HSS Reduced Shank Mechanics Length Drill Bit Set (AST-TS29) delivers a significant performance advantage over conventional drill bit designs across nearly all materials. Built around a patented spiral-fluted stepped-tip design, these bits self-center on contact, eliminating bit walk and the need for pilot holes. Precision ground from heat-treated M2 High Speed Steel and finished with an Onyx oxide coating, each bit resists chip build-up and withstands demanding applications. Mechanics-length construction and three-flat shanks with reduced shanks above 3/8" ensure superior chuck grip and access in tight, confined spaces.
