Product information

Product benefits

Wobble-free drive
The TX internal, multi-tooth drive allows easy and secure screw driving from setting to countersinking.
Timber is not torn out
The drilling point relieves tension in the timber, thereby preventing cracks.
No predrilling
Predrilling is not needed, even in most hardwoods. But given the many different properties of hardwoods we would always recommend testing the application.
