SHORT SPIRAL DESIGN: The specially shaped spiral flute reduces the pull-in effect, making it ideal for drilling in metal sheets. QUICK CUT GEOMETRY: With a 130° point angle and special sharpening, these steel drill bits produce small metal chips and are three times stronger than cobalt bits. EXTREME HEAT RESISTANCE: These HSS drill bits withstand high temperatures while maintaining hardness, ensuring durability even under heavy loads. VERSATILE PERFORMANCE: Suitable for all stainless steel grades, as well as all types of steel, gray cast iron, and steel castings. REDUCED BREAKAGE RISK: The cylindrical drill bit's shaft and spiral are differently hardened to minimize the risk of breakage.
