Data on


In 2008, the first prototype of today’s mud drilling system “E-Z-Jet” was created. E-Z stands for “easy”, i.e. “lightweight”. The system was continuously developed further and presents itself today as the smallest, lightest, but most powerful HDD mud drilling system on the market. It can also be used for rock drilling.

The frame dimensions are the same for Mini Twinny and E-Z-Jet; both systems can be mounted in the same wall flange.
