Product Description

Hex-shank impact-rated step drill bits feature a hex shank and install into impact drills with standard three-jaw chucks. They are also known as impact step bits. These cone-shaped bits have steps of increasing diameter marked along their cutting head. As each bit is pushed into a piece of sheet metal or other thin material, each step on the bit widens the hole. The bits also have a self-starting split point that prevents the bits from moving, or walking, when starting to drill, which eliminates the need for using a center drill to create a starter hole before drilling.
