Version:
Sturdy version with right-hand helix and shank to DINxa01835-B. Special geometry for use on machines with synchronised spindle drives. The tap is guided by the synchronised spindle on the machine. Special TiAlN-S coating for optimum tool life. For use with emulsion (fat content minimum 8%).Form E (lead chamfer: 1.5 – 2 turns) for the deepest possible thread depths.
Recommendation:
For TOOLOX materials we recommend deviating from the DIN data (see table) by drilling the tapping hole ⌀ 0.05 to 0.3mm larger.
Note:
For use on synchronised spindles, the GARANT quick-change tapping chuck No. 338100 − 338121 with minimum length adjustment (MLA) ensures very high process reliability.
