Carbide drill head with straight head, 22mm T-slot (7/8")

The straight carbide head with 22mm T-Nut from ROWO has been developed for the hardest drain blockages. On the flat front side are pins made of carbide, which drill into concrete, urine scale, lime, industrial deposits and other hard incrustations in the pipe. Different diameters are available, so that the best variant can be chosen depending on the plugging and pipe diameter. The drill heads are especially suitable for down pipes.

Up to a diameter of 40mm the carbide miller is closed at the front, from 65mm diameter the front is ring-shaped. This has the advantage that it is not necessary to work with the full surface, but the blockage can be milled out in a ring shape on the outside. The pins are made of carbide carbide / carbide and are soldered firmly to the drill head.

The carbide head has a 22mm T-Nut coupling for connection to appropriate drain cleaning cables. For milling work, reinforced drain cables, i.e. S drain cables or S drain cables with core, should always be used. This is the only way to ensure maximum power transmission from the drain cleaning machine to the tool.
