Core Barrel with Roller Bits is a heavy-duty drilling tool engineered for bored pile and deep foundation construction in extremely hard rock formations and large boulders. Equipped with high-performance roller bits, it crushes and fractures rock efficiently, reducing drilling resistance and improving penetration rates. Manufactured from high-strength alloy steel with a reinforced barrel structure, this tool offers outstanding durability, reliable performance, and a long service life under demanding working conditions. Compatible with leading rotary drilling rigs such as Bauer, SANY, XCMG, Zoomlion, Sunward, and Soilmec, the Core Barrel with Roller Bits is an ideal solution for large-diameter piles, bridge foundations, and other challenging foundation drilling applications.
