Alpha 2 Flute HSS Step Drill
Drill and deburr in a single process with the Alpha 2 Flute Step Drill. Made from premium HSS M2 steel and TiN coated for longer life, this drill bit is designed for smooth, high-performance cutting. The self-starting split point eliminates the need for a pilot hole, while the 2-flute design ensures clean, round holes. Laser-etched sizes make it easy to identify the correct step, and the 3-flat shank prevents slippage in your drill chuck.
