The curved thread system really makes a difference in long hole drilling. With CT55 and 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 ST58 and 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 CT system an ideal solution for automated drilling.
Curved thread innovation
Packed with power
Innovated to cut costs. Uncoupling problems and sudden transversal breakages cost lots of time and are entirely unpredictable. The CT55 and CT67 top hammer tool system is built to last and deliver without interruptions. Check out other features, benefits and values.
