The Core Barrel with Bullet Teeth is a heavy-duty drilling tool designed for bored pile and deep foundation construction in hard rock, weathered rock, boulders, and other challenging geological conditions. Equipped with high-performance tungsten carbide bullet teeth, it efficiently fractures rock while maintaining excellent drilling stability and wear resistance. Manufactured from high-strength alloy steel with reinforced welding, the core barrel delivers reliable performance, extended service life, and high drilling efficiency. It is compatible with most major rotary drilling rigs, including Bauer, SANY, XCMG, Zoomlion, Sunward, and Soilmec, making it an ideal choice for demanding foundation drilling projects.
