Step Drill Bits
MILWAUKEE Step and Drill Bit 10PC Set
Milwaukee step drill bits with Jam-Free performance feature a dual-flute design delivering up to 2x faster holes, up to 4x longer life and up to 50% more holes vs. competitors. Ideal for drilling small and large-diameter holes in steel and plastic, these bits are optimised for cordless drills in high speed. The Rapid Strike™ tip allows for a fast and accurate start that generates less heat, resulting in longer bit tip life. Black oxide coating also enhances durability, hole quality and bit life. For user convenience and accuracy, each bit has laserengraved reference marks you can see while drilling. The 3-flat SECURE GRIP™ shank ensures a solid connection with the drill chuck. Thunderweb HSS Jobber Drill Bits are optimised for a wide variety of drilling applications such as ferrous & non-ferrous metals, plastics and wood. The THUNDERWEB design is characterised by a conical shaped web which gets thicker towards the top of the drill bit. Standard Jobber Drill Bits have a constant thickness throughout their length.
