Handle Drilling Tasks with Ease:‌ Engineered with four razor-sharp cutting blades, our step drill bit set delivers swift, vibration-free drilling performance. The advanced geometry slices through steel, aluminum, copper and other rigid materials with surgical precision – like a hot knife through butter
Upgraded M35 Bits:‌Made from M35 cobalt high-speed steel (HSS), With its high hardness (HRC 64–66), excellent red hardness, and enhanced wear resistance for tough jobs. Our M35 cobalt steel drill bits last up to 8 times longer and drill 3 times faster than standard bits
Advanced Coating: The TiAlN coating improves surface hardness, offers reliable resistance to high-temperature oxidation, and and excellent thermal hardness, making it suitable for demanding applications
Effective Step Size: 19 step :(7/8 “, 1-1/8”, 1-3/8“),1*3/8“ Shank. When it comes to drilling hard materials, the angle of the drill tip matters. That’s why we’ve designed our drill bits with a 135° cutting angle. This angle reduces self-wear and provides a larger stress area, resulting in cleaner, more efficient drilling
Easy Organization & Identification: Our step drill bits for metal come with a handy storage case, ensuring effortless organization and portability for all your drilling tasks. Clear size markings on each bit allow for quick identification
Widely Application: Our metal step drill bits are ideal for drilling into metal sheets, stainless steel, aluminum, copper, plastic, and other thin materials
