Therm Drill

Screwed connections with low wall thicknesses –
time-consuming and expensive?

When working with thin-walled materials, you often find yourself confronted with the problem that it is only possible to make 1-2 threads. Generally speaking, this number of threads is not sufficient for supporting a load.

In the past, the solution to this problem was to use rivet, weld or clinch nuts. Every practitioner is well aware of the drawbacks of these traditional joining techniques.

Thermal friction drilling – the time and cost-saving alternative!

A combination of drilling and forming, using the Thermdrill tools not only produces a precision hole without cutting, but also the displaced material is used at the same time for producing a bushing hole – entirely without the use of additional materials! It is possible to make up to three times as many threads in this local thickening of the material. Resulting in a highly stable screwed connection, capable of satisfying even the most strength and fit, quality requirements.

Geometry and suitable material qualities

Thermdrills can be used for a wide range of diameters and wall thicknesses. The strengths of thermal friction drilling really come into their own when working with closed hollow profiles, such as tubes. When working with circular tubes, the Thermdrill technique offers a decisive advantage. The material that is displaced upwards automatically forms a collar, which in turn compensates for the curvature of the tube and also provides an ideal flat surface for nozzles, valves, etc.
