Raise Boring Cutter

The raise boring cutter is mainly used for excavating ventilation shafts in mines. In response to the requirements for drill bit wear resistance and sealing performance in harsh mine environments, our R&D personnel adopted large-diameter wedge-shaped teeth on the main cone of the product, improving wear resistance. The high-quality NSK thrust bearings used increase bearing load capacity, and combined with German-imported floating oil seals, the sealing durability of the raise boring cutter product is strengthened, extending bearing life. Together with the use of A and B cutter types, full coverage of the bottom-hole crushing zone can be achieved.
