Step drill bit 10-45 mm, titanium coated, straight shank, double flute, triangular shank hole

1. **Durable and Robust:** Made of classic high-speed steel with a titanium coating, this drill bit is durable and allows for easy drilling of various metals such as plastic, aluminum, copper, and stainless steel. The titanium coating reduces friction and promotes heat dissipation. 2. **Straight Cut:** The double-edged design ensures a cleaner and more stable cut. Low pressure is all that's needed. Automatic deburring during drilling allows for faster and more accurate cuts. 3. **Double-Edged Design:** The double-edged design prevents slippage, quickly removes chips and burrs, and allows for faster and more accurate drilling and cutting with low pressure. 4. **Applications:** Step drill bits can be used for chamfering, milling, drilling, or boring. They are widely used for drilling various materials less than 5 mm thick, such as sheet metal, aluminum, insulation panels, PVC, and wood. 5. **Advantages:** The stepped design allows you to drill holes of different diameters with a single drill bit, eliminating the need to purchase multiple bits and saving space and money. The triangular shank makes it easy to insert into electric screwdrivers, drills, and impact drills. The double-edged blade and X-shaped opening ensure a faster and cleaner cut; the three-sided shank design prevents the drill bit from slipping in the chuck.
