With the Phantom hss twist drill bit conforming to din 1869, you easily drill deep and precise holes in metal where standard drill bits fall short. Thanks to its 150 mm overall length and 100 mm flute length, you bridge large distances through thick profiles, tubes, or hollow cavities without relying on unstable extensions. The durable hss construction with two cutting edges delivers a clean, accurate start and controlled material removal in alloyed and unalloyed steel. In addition, the steam-tempered surface treatment reduces friction, enhancing chip evacuation and extending tool life. Its 3 mm cylindrical shank fits securely into standard drill chucks for dependable deep-hole drilling.
