The HSS cobalt spiral drill provides long-lasting performance when drilling in stainless steel. The extended lifespan is due to a 5% cobalt alloy content and fully ground HSS (high-speed steel), which provides outstanding surface quality, wear resistance, and heat protection. Equipped with two cutting edges and two flutes, chips are removed quickly so the hammer drill lasts even longer. This hammer drill can be used for alloyed and unalloyed steel, stainless steel, cast iron, cast steel, acid- and heat-resistant steel. The HSS spiral drill made of steel is manufactured according to DIN 338. The drilling head is of type N (notch angle) with a 135-degree point angle and a diameter tolerance of …

The ground HSS spiral drill bit for drilling through metal with maximum precision. The exposed 135-degree split self-centering point of the drill head combines active cutting with perfect centering without displacement for maximum precision. With the split tip, it is also unnecessary to mark center points in advance or pilot drill up to 10 mm. This precision-ground drill head, made of HSS (high-speed steel), provides up to 40% faster drilling and up to 50% lower clamping pressure than standard ground HSS cutting edge drill heads. This drill head is designed for drilling holes in alloyed and non-alloyed steel, cast steel, cast iron, sintered iron, reduced cast iron, non-ferrous metals and hard …
