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

1. **Durable:** This drill bit is made of classic high-speed steel with a titanium coating, ensuring durability and easy drilling of various metals such as plastics, aluminum, copper, and stainless steel. The titanium coating reduces friction and promotes heat dissipation. 2. **Straight Cutting:** The double-edged design ensures cleaner, more consistent cuts. Only low pressure is needed. Automatic deburring during drilling enables faster, more precise cuts. 3. **Double-Edged Design:** The double-edged design prevents slippage, quickly removes chips and burrs, and enables faster, more precise drilling and cutting at low pressure. 4. **Applications:** Stepped 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 thin metal sheets, aluminum, insulation boards, PVC, and wood. 5. **Advantages:** The stepped design allows you to drill holes of different diameters with a single bit, eliminating the need to purchase multiple bits, 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 notch ensure faster and cleaner cuts; the three-sided shank design prevents the drill bit from slipping in the chuck.
