Established more than 60 years ago, Volz Drilling Tools GmbH is still an owner-managed family business with 20 high-qualified and motivated employees. Our core competence is the production of high-quality drilling tools made of high speed steel (HSS) and solid carbide. Besides our standard product program we also manufacture tools, which are designed for individual usage for many different industries. Modern manufacturing engineering, high-end materials and a consistent quality assurance guarantee a continuous high standard of our products and allows us to be flexible in regard of the needs of our customers. Slight configurations, decades of experience and our own demand in regard of quality and precision make us a perfect partner in the area of drilling tools.
In order to ensure the outstanding quality and the strict process standards
at Volz Drilling Tools, we regularly conduct comprehensive material
and hardness tests.
Each individual production stage up to the delivery is subject to a steady
control. Strict inspection procedures and complete traceability ensure
the high manufacturing standard on which our customers can rely on.
Since 2007 Volz Drilling Tools GmbH is holder of the quality certificate
DIN ISO 9001.
at the highest level is the ultimate ambition of our company policy.

In many applications, hard coatings offer important advantages such as higher durability, toughness, heat resistance and better gliding properties.
Due to our collaboration with well-known German coating companies, we offer you the possibility to coat your drilling tools with the hard coatings
TiN, TiAlN or TiCN.
