Information.

Flowdrill is a solid tungsten carbide tool, capable of locally displacing material to form increased material thickness. This increased material thickness allows for a stronger fastening connection by tapping, brazing or welding. 

Flowdrill is available in many sizes, suitable to drill holes from 1mm to 40mm with material thicknesses from 0.5mm to 10.0mm. Flowdrill can be used in steel, stainless steel, aluminium, copper and some types of brass.
