Core Barrel Roller Bit for Hard Rock Foundation Drilling

Built for the toughest drilling conditions, this heavy-duty roller bit core barrel is engineered for deep foundation drilling, bored piling, and abrasive rock formations over 100MPa.

Unlike standard rock augers, the integrated roller cone design crushes hard rock with higher efficiency, longer service life, and greater drilling stability — making it the ideal core barrel for hard rock and demanding piling projects.
