Demand in drills with torques beyond 400 kNm is enormous right now...

Extensive drilling equipment has been supplied to the Citybanan tunnel project in Stockholm, for the Stockholm Södra construction site. This includes, among other things, 8 down-the-hole hammers W100, W120, and W150 made by Wassara, more than 200 drilling tubes of the diameters 88.9 to 193 mm, as well as WASP150 high-performance pumps. The tunnel variant was chosen because restricted space conditions prevail in the overground area of the Old Town .
