Wengeler & Kalthoff - Werkzeuge für Bergbau, Hüttenindustrie und Bauindustrie

Manufacturing high-quality specialist tools for the following sectors:

Mining and tunnelling

It is now difficult to imagine a mining industry without high-quality tools from Wengeler & Kalthoff. We have been supplying the mining sector for over one hundred years and as a result have extensive know-how in dealing with the problems facing this important industry.

The mining industry (coal, salt and potash, slate and clay etc.) is our key partner and we provide both advice and support to companies in this sector. The pictures on the following website pages only contain a selection of the huge range of products we manufacture for mining clients.

The metallurgical industry

Experience in drilling technology combined with know-how acquired from the iron and steel industry has enabled Wengeler & Kalthoff to develop high-quality drill tools for the metallurgical sector. One-piece and multi-piece drill steels can be supplied to cope with a wide range of drilling processes.
Wengeler & Kalthoff drill rods are renowned for their reliability and long service life and have proved highly efficient when drilling tap holes for blast furnaces, for example.

The carbide-studded facing plate, another innovation from Wengeler & Kalthoff, allows the surface of the tap-hole crucible to be smooth ground in such a way that the nose of the notch gun is able to sit flat against it.

Wengeler & Kalthoff have also developed a coupling sleeve with an integral check valve that prevents molten iron from running back through the coolant duct and into the hammer drill.

Construction industry

Wengeler & Kalthoff produce tools of the highest quality for the construction industry. Whether it be structural engineering or tunnelling, road construction, civil engineering or quarrying, we can supply the right tool for the job.

We also manufacture high-grade one-piece rods, ready swaged and welded, for the trenchless laying of supply pipes and cables.

We only use the highest grade of tubing manufactured from tool steel and heat-treatable steel. Our expertise in this area, combined with the use of compatible tempering and finishing processes, gives our products exceptional performance and a long service life.
Wengeler & Kalthoff represent an important link between the equipment manufacturers and the specialist drilling contractors.
