Solid drill bit CrazyDrill Cool SST

for stainless steelmulti-purposetungsten carbide

With CrazyDrill Cool SST-Inox, Mikron Tool introduces a twist drill type for stainless steels, heat- and acid-resistant steels and CrCo alloys in the diameter range from 1 up to 6.35 mm (.039“ up to .250“, fractional inches available) and for drilling depths from 6 x d to 40 x d. The tungsten carbide drill is designed with internal helicoidally arranged cooling channels which bring up to four times more coolant volume to the drill tip. The new cooling system, the new design of tip and flute as well as the innovative coating enable drilling in one single step up to a drilling depth of 40 x d with high performance in terms of quality, tool life and machining time. CrazyDrill Cool SST-Inox, the small solid carbide drill bit of Mikron Tool for stainless steel, heat- / acid-resistant- and CrCo alloys, distinguishes itself through extremely high drilling performance. One single step is sufficient to drill the full depth of 40 x d – without pecking. Various factors are responsible for this absolutely singular performance: an innovative geometry and coating and a new through-tool coolant. The new chip flute profile is divided into two areas: a front chip flute area with a special chip breaker shape ensures compact, short and curved chips; a rear chip flute area with extended flute shape ensures perfect chip removal. The new high-performance coating (copper red) is heat- and wear-resistant, prevents build-up edges and promotes uniform chip flushing. A very long tool life is given. The extraordinary performance and process accuracy of CrazyDrill Cool SST-Inox is based in first instance by its cooling characteristics
