The DRABUS-frictiondrilling process creates the possibility of making holes in thin metal sheets and thin-walled tubes in just a few seconds without chips, while forming a bushing at the same time. This bushing can be used as a soldering or welding connection or as a bearing bushing. By tapping a screwthread it can also be used as screw connection. The DRABUS-frictiondrilling process replaces and eliminates the use of rivet or welding nuts as well as steel insert bushings. It accordingly saves time, work and material.
The DRABUS-frictiondrilling process is suitable for: Making holes from 2-20 mm in all kinds of steel up to 1200 N/mm2 tensible strength, including stainless steel, aluminium, brass and copper with a thickness of 1 to 6 mm depending on the material used and the hole diameter.
