Description
IDEAL step drill bits for precise, repetitive drilling through the toughest materials including brass, carbon steel, cast iron, stainless steel, and more. These tough and reliable tools are constructed with a rugged titanium nitride exterior coating for protection, edge retention and corrosion resistance. Each step is gradually blended to ease stepping through hole sizes; reducing the need to keep changing drill bits. Split point design eliminates the need for a starter hole or punch and delivers three times faster starts, saving valuable time. The double-fluted design provides balanced cuts, more cutting surface compared to a single flute design, and cooler operation.

- Drills 16 different holes sizes 1/4 in. to 1 1/8 in., Step Increments 1/16 in., Step Thickness 1/16 in.
- Split-point design for faster starts
- Unique double-fluted design for balanced cuts and cooler operation
