In contrast to an on-site technician, the service technician concerned can consult other specialists from our company at any time and has access to all documentation.

Sustainable Conversion

It does not always have to be a new acquisition. We can also update an older deep drilling machine to meet the latest standards. Conversions can be carried out both at your own plant and at ours. Optionally, we also offer static acceptance tests.

You receive the full warranty – both on parts and on the work performed.


Production in the rebuild phase

To avoid downtime, we can offer you a loaner machine (if available) or manufacture your parts in-house.

➔ Second Life offers

We buy back our used TBT deep hole drilling machines. These are rebuilt with refurbished and/or with new components. If necessary, the electrical system of the machine is replaced with an up-to-date control system. Protective devices are always adapted according to the safety regulations with CE marking.

Spare parts

In addition to our original parts for your TBT machines, we also offer specific spare parts for deep hole drilling machines made by Nagel, GKT, SIG and Heidenreich & Harbeck.
