The variable diameter of the Milwaukee Tool Black Oxide Step Drill Bits lets you drill precise holes much faster than normal drill bits in steel and plastic. Rapid Strike™ tip allows for a fast and accurate start while producing less heat, which results in a longer bit tip life.

The Black oxide coating also enhances durability, hole quality, and bit life. For user convenience and accuracy, each bit has laser-engraved reference marks you can see while drilling. The 3-flat Secure-Grip™ shank ensures a solid connection with the drill chuck. The #1 Step Drill Bit has 13 hole sizes in 1/32" increments ranging from 1/8" to 1/2". This bit's dual flute design ensures jam-free performance with most professional 18-volt cordless drills.
