Detailed information

IDEAL® step drill bits are designed for precise, repetitive drilling through the toughest materials like brass, carbon steel, cast iron, stainless steel, and more. These robust tools feature a rugged titanium nitride exterior coating that ensures protection, edge retention, and corrosion resistance. Each step is gradually blended to ease transitions through hole sizes, reducing the need for constant bit changes. The split point design eliminates the need for a starter hole or punch, delivering starts that are three times faster and saving you valuable time. The double-fluted design offers balanced cuts, more cutting surface compared to single flute designs, and cooler operation, making these bits the best choice for efficiency and durability.

I would absolutely recommend these lever connectors and will surely be using them in the future! Those connectors were super easy to work with, didn’t seem flimsy like other brands, and were super easy to install as well as remove
