Step Drill Bits

Step drill bits are designed to create precise, round holes in various sizes with a single bit, eliminating the need for multiple bit changes. Ideal for thin materials up to 1/8" thick, they also excel at enlarging and deburring existing holes for a smooth finish.

Hex-Shank Impact-Rated Step Drill Bits
3-Flat Shank Step Drill Bits
These step drill bits feature a three-flat shank design to ensure a secure grip in the drill chuck, minimizing slippage during operation. Their cone-shaped structure includes incrementally larger diameter steps along the cutting head, allowing for precise hole enlargement in sheet metal and thin materials with each step. Equipped with a self-starting split point, these bits eliminate 'walking' at the start of drilling, removing the necessity for a pre-drilled starter hole.
