Milwaukee Step Drill Bits with JAM-FREE Performance use a dual-flute design that delivers up to 2 times faster hole times, up to 4 times longer life and up to 50% more holes per battery charge than competitors. Ideal for drilling small and large-diameter holes in steel and plastic, these bits are optimized for Cordless Drills in High Speed. A Rapid Strike tip gives a fast, accurate start that generates less heat, so the bit tip lasts longer. A black-oxide coating also improves durability, hole quality and bit life. For convenience and accuracy, every bit has laser-engraved reference marks you can see while drilling, and the 3-flat Secure-Grip shank ensures a solid connection with the drill chuck. The Step Drill Bit 3-Piece Set includes bits #1 (48-89-9201), #2 (48-89-9202) and #4 (48-89-9204). Jam-Free Performance in high speed with most professional 18-Volt cordless drills with lithium-ion battery technology.
