The long, ground HSS spiral drill bit bores deep holes in metal with the highest precision. Its greater length allows for drilling deeper holes. The self-centering drill tip with a cross-ground design and a tip angle of 135 degrees enables perfect centering without wandering. Thanks to the cross-ground drill tip, there is no need for center punching or pre-drilling for diameters up to 10 mm. This precision-ground drill bit made of HSS steel drills 40% faster and requires 50% less feed force than conventionally ground HSS drill bits. The long ground HSS spiral drill bit is manufactured according to DIN 338. It belongs to drill type N (small side cutting angle) with a tip angle of 135 degrees and a diameter tolerance of h8.
