Step Drill Bits
Available7 products
Step drill bits each create perfectly round holes in a range of sizes without requiring multiple bits to be swapped out in the drill. These bits can also be used to enlarge and debur existing holes. Step drills are suitable for drilling thin materials up to 1/8" thick.

3-Flat Shank Step Drill Bits
The shanks on these step drill bits have three flats that help prevent the bits from slipping in the drill chuck during drilling. 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.
