Rockmore International offers the new Multi-Dome carbide design for DTH drill bits, engineered to provide faster bit-penetration rates and ensure greater overall insert life. Its dual-diameter design is said to enhance bit performance by improving rock-chip geometry, leading to more efficient chip flushing. Two radii on the insert dome help increase carbide life, while extended dome height ensures faster bit penetration rates. The Multi-Dome carbide is available for DTH bits up to 10 inches in diameter.
