CT55 and CT67 curved thread systems are designed for surface mining and quarrying. These systems accommodate higher drilling power than the standard ones and feature a curved profile that reduces stress levels strategically while optimizing the product for fatigue strength.
Features
-
Patented design
The unique, patented curved thread system provides a bigger X-section where needed and significantly reduces stress levels. This leads to fewer breakages and increased service life.
-
Productivity boost
The curved threads achieve a faster rate of penetration per meter and more meters per engine hour. These factors - along with problem-free drilling, easy coupling/uncoupling and good hole quality/hole straightness - provide increased productivity during drilling operations.
-
Advanced technology
The specially developed shoulder-driven system achieves an efficient energy transfer along with a stiff, strong connection. Easy coupling/uncoupling leads to minimal rattling.
