ÜRÜN AÇIKLAMASI

12 1/4 inch Tricone Rock Bit – IADC 117 is a three-cone drilling bit with a nominal diameter of 311.2 mm and a 6 5/8 API REG connection. The IADC 117 class identifies a Milled steel tooth cutting structure and Gauge-protected sealed journal bearing arrangement for very soft and soft formations.

The reference operating range is 40–300 RPM with 80–250 kN recommended weight on bit. Poor bottom-hole cleaning causes cuttings to be reground, raises heat and shortens cutter life. Final operating values must be checked against the formation, rig capacity and circulation conditions on site.
