BOSCH 2.608.577.178 HSS PointTeQ spiral drill bits are a pack of 10 precision-ground 1 mm diameter high-speed steel (HSS) twist drill bits designed for fast, accurate metal drilling. They feature a 135-degree self-centering split-point tip that prevents wandering, eliminates the need for pre-punching or pilot holes up to 10 mm, and enables up to 40% faster drilling with 50% lower feed pressure compared to standard HSS bits. The black-oxide coated flute ensures fast chip removal, reduced heat, and wear for increased lifetime. Suitable for alloyed/non-alloyed steel, cast iron, non-ferrous metals, and hard plastics. Manufactured to DIN 338 standard (Type N) with cylindrical shank.
