Experience, quality, reliability

Why be modest when we have become the market leader in deep drilling? We as TBT Tiefbohrtechnik GmbH + Co have succeeded in convincing large parts of the world with our performance after the company was founded in Dettingen/Erms in 1966. In the meantime we belong to the internationally operating Nagel Group.

We see our customers as partners on an equal footing, to whom we reliably assist in all matters concerning our deep hole drilling machines and deep hole drilling tools and supply them with precision in perfection. Our contract manufacturing team carries out a wide variety of orders for our customers on more than 30 machines.

The company TBT is a pure family business, integrated in the internationally active Nagel-Group.

TBT Quality and Environmental Policy


Continuous improvement

Quality, service, technologies, environmental protection and occupational safety are constantly improved and developed at our company. Our goals are ambitious and result in continuously improving our performance and reducing our environmental impact. In all areas, we evaluate processes and risks at regular intervals and, if necessary, define appropriate measures.

Customer-oriented thinking and acting

Our entire company is focused on the development and manufacture of products and services of the highest possible quality. The goal is to have satisfied and enthusiastic customers. Each employee contributes at his place self-responsibly to realize the customer requirements. We commit our suppliers to our quality and environmental requirements.


Each employee is personally committed to the quality and environmental requirements. The use of the best available technology, with due regard for economic efficiency, ensures capable, safe and environmentally compatible manufacturing processes. Maximum quality also includes compliance with demanding environmental standards. Legal and official tasks and requirements represent minimum standards for TBT.

Environmental protection

The protection of the environment through the use of state-of-the-art technology with regard to economic justifiability is an integral part of our actions. We support environmental protection by using resources sparingly and by relying on low-emission and low-waste production techniques. With the voluntary application of the environmental management DIN EN ISO 14001 TBT strengthens its efforts for an efficient and sustainable environmental protection.



Our managers work permanently to promote quality, safety and environmental awareness as well as the personal responsibility, competence and flexibility of our employees. It is the task of every manager to realize the company’s quality and environmental goals. Joint planning and implementation of projects, personal example and a management style aimed at participation strengthen the quality and environmental awareness of all employees.


Error avoidance

Through prevention and targeted consideration of all processes, we strive for 100 percent quality fulfillment. Defects are to be avoided and not eliminated.

Many machining tools have internal cooling. When it comes to long tool shanks, the routing of the cooling channels is an important factor in terms of quality.
