Tung-Tri – Bed Part – AH120


Improved productivity & Excellent surface finish
-Large rake angle on cutting edges contribute to outstanding surface finish
even with doubled feed per tooth compared to the competitor.

Increased tool life
-AH120 allows stable machining without fracture even under 2 times higher
feed per tooth than the competitor, increasing the tool life by 25%.
