1.ETERNAL raise boring roller cutters have been field-proven under a wide range of rock conditions. Optimized on cutter body structure and tooth spacing in accordance with the mechanical properties of rocks from various formations, these cutters are applicable to tunneling in rock strata of varying hardness including sandstone, limestone, granite and basalt , catering to diverse engineering requirements.
2.By adopting scientific calculation and analytical approaches, we accurately determine the optimal cutting efficiency and moving direction for each row of carbide teeth, allowing every carbide insert to achieve maximum rock fragmentation area and volume upon contact with the borehole wall.
3.Featuring exceptional wear resistance, stable performance and long service life, our raise boring roller cutters cooperate seamlessly with raise boring machines for high-efficiency rock breaking. This shortens construction cycles, boosts drilling efficiency and reduces overall project costs.
The raise boring roller cutters are widely applied in underground engineerings including mining, hydropower and transportation.
