Description
Twist drill bit with cylindrical shank

Design: Very stable drill bit.Ground profile, right-hand cutting, uncoated surface, nitrided margin from 2.4 in diameter, with precise tip grinding and a wide chip groove with a strongly rounded bottom, high heat resistance.Correction according to DIN 1412, shape A.Side rake angle greater than normal, core thickness greater than normal, no taper.

Application: Due to plaque nitriding and wide chip flutes suitable for drilling holes deeper than 3 x D.Intended in particular for alloyed and unalloyed steels and castings with a strength over 800 N / mm2, for cold and hot work steels, bearing steels, high-alloy steels, tempering and carburizing steels.
