The crossblade auger is probably the most popular drain cable tool for mounting on drain cables. The two leaves offset by 90 degrees make the characteristic cross appear when viewed from the front. The sheets cut in steps form a kind of tooth profile. This allows all types of pipe blockages to be effectively drilled out.
The tip of the crossblade auger is guided via the drain cleaning cable to the flow point of the pipe plugging. From here, it bores through the centre of the constriction in the pipe and expands it. Soft incrustations and deposits of oils, grease and soaps can be removed, as well as hard incrustations such as solid deposits of lime and other residues that may form in the pipe.
Ideally, after using the crossblade drill to pierce and expand the pipe plugging, a chain knocker is also used. This can slide into the passage drilled by the crossblade auger and remove any remaining residue on the pipe wall. This allows the best results to be achieved in drain cleaning.
The cross-blade augers from ROWO are made of two staggered blades, which are soldered together and to the holder. With hard deposits, the tooth profile of the blades wears off quickly and becomes round. They should therefore only be used for softer deposits.
In contrast, the blades of the rak crossblade drills are made of hardened steel. This is clearly noticeable in the application with harder pipe blockages: The tooth profile of the blades is noticeably less worn. The rak crossblade drills therefore have a longer service life and a wider range of applications. They are inserted and riveted into the holder with the T-Nut.
No matter which variant you choose - you can rely on the quality of the drain cable tools from the ROKA Store range!
