Feed f in steel < 750xa0N/mm2:0.2 mm rev. Colour ring:without Type of product:Jobber drill Version: Compared to DIN 345 the flute length is longer by the drill bushing height. Thus the effective drilling depth is unaffected. Special surface treatment for improved chip evacuation.With point geometry shape A. Advantage: For drilling through drill bushings in tool making, machine building and series production. Particularly important for drilling into uneven, inclined or arched surfaces. Recommendation: Maximum drilling depth:L2 = LC - 1.5 × DC. Note: For suitable reducing adapters for tools with MT shanks see No. 343000-343530.
