ÜRÜN AÇIKLAMASI

6 1/2 inch Tricone Rock Bit – IADC 217 is a three-cone drilling bit with a nominal diameter of 165.1 mm and a 3 1/2 API REG connection. The IADC 217 class identifies a Milled steel tooth cutting structure and Gauge-protected sealed journal bearing arrangement for soft to medium-hard formations.

The reference operating range is 40–140 RPM with 60–140 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.
