Curved thread system CT67

The curved thread system really makes a difference in long hole drilling. With CT67 you get a predictable performance without interruptions, as well as trouble-free coupling and uncoupling at lower cost per meter.

Features

Unique curved design

The unique, patended curved thread design provides strength where it is needed and distributes the load evenly on the thread revolutions.
Stronger geometry

The stronger geometry minimizes tool breakages and boost service life on drill tubes with +30-60%, compared to standard ST68 products. The extended service life dramatically reduces the cost per meter, but also means less manual handling of heavy products.
Enabler for automation

Predictable discards, long service lives and simple coupling characteristics makes CT67 an ideal solution for automated drilling.
