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

The rounded hard metal head with 22mm T-Nut from ROWO has been developed for the hardest drain blockages. Due to its shape, it is more flexible than the version with a flat head. In addition, the rounded drill head mills slightly differently than the flat version. On the semicircular front side there 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 blockage and pipe diameter. The drill heads are especially suitable for down pipes.

The rounded carbide miller has a diameter of 45mm or 55mm, making it ideal for pipes up to 100mm. The pins are made of 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.
