Take your metalworking projects to the next level with this spiral flute step drill bit, engineered for professionals and DIY enthusiasts alike. Designed with an advanced triple-flute structure and coated with ultra-durable AlTiN, this bit cuts smoothly through a wide range of metals while reducing friction, heat, and wear. Whether you’re expanding holes or tackling tough stainless steel, this drill bit delivers clean, precise results every time.

Product Features

This step drill bit is crafted from high-speed M35 cobalt steel, ensuring toughness and superior bending strength. The AlTiN coating, rated at 89 HRC, resists heat up to 1650°F and provides excellent wear resistance and low friction performance. Featuring nineteen step sizes ranging from 1/4 inch to 1-3/8 inch, it eliminates the need for multiple bits when working with sheet metals, plastics, or composites. It includes a 3/8 inch shank for secure and stable grip in most standard chucks.

M35 cobalt steel – Built for tough materials like stainless steel and low-carbon steel
Nineteen step sizes – Versatile drilling from 1/4 inch to 1-3/8 inch in one tool

When to Use

This step drill bit is ideal for metal fabrication, automotive work, HVAC installation, or any project requiring smooth, precisely sized holes in metal, plastic, or composite sheets.
