The milling head is driven by conventional HP cleaning vehicles within an operating pressure range of 80  (8,00 kPa, 1160 psi) to 150 bar (15,000 kPa, 2,176 psi) and a conveying performance of the pump between 250 and 450 l/min. To avoid damages to the sewer, the milling head has to match the inside pipe diameter.

“Automatic impact boring apparatus” have the following operating principle:

The device is propelled through the sewer line using high pressure water jets emitted from nozzles at the tail end of the impact borer. In this process, the pipe wall is cleaned and the already loosened deposits are flushed away. The milling head is operated hydraulically in both the rotating and impact motions. Depending on the operating pressure, it impacts the deposits with 1,000 to 1,500 blows per minute, while milling at the same time at 100 to 200 rpm. The pressurized water used for the milling and hammering action is then used to clean the tool.
