12¼” TCI IADC 517

1. Product Overview

The 12¼” TCI IADC 517 is a tricone roller-cone drill bit engineered for efficient rotary drilling through soft to medium-hard formations. Its tungsten carbide insert (TCI) cutting structure provides effective rock penetration, while the 12¼-inch diameter is widely suited to oil, gas, water-well, geothermal, mining, and foundation drilling operations. The IADC 517 configuration offers a balanced combination of penetration efficiency, durability, and controlled wear for demanding drilling programs. It is a commercially strategic choice for operators seeking dependable drilling performance and optimized cost per metre.
