Product Description
The 65–113 mm concave PDC family covers 2.56–4.45 in and is intended for oil-and-gas, offshore, or directional holes in soft, medium, and consolidated formations. Its tri-wing, coreless face provides three separated cutter paths around a concave center. The supported applications are summarized in the oil and gas drilling archive, and the bonding requirement can be reviewed in the consolidated formation archive.
The filename lists 65, 75, 94, and 113 mm sizes and explicitly identifies PDC diamond-composite construction. It does not state body material or connection. Inspect the three wings, center clearance, cutter support, and gauge for the selected diameter. M332 is used from the allowed PDC IADC list. The coreless description does not justify a separate circulation claim, so nozzle and port details remain blank until confirmed. Record the exact family member on every run; the 65 mm and 113 mm versions should not share one assumed hydraulic or torque response merely because their geometry is related.
Use 2,000–10,000 lbf/in WOB and 60–300 RPM. Every listed diameter is smaller than the 8.5 in reference associated with 250–650 gpm, so no flow value is copied into this product. Select actual hydraulics from the bit and assembly. Gravel is not suitable for PDC because loose clasts can interrupt shearing and damage cutters. The PetroWiki drilling reference offers general background. If torque spikes or the concave center packs, reduce engagement and inspect before resuming. Compare gauge measurements at identical locations on every size. Archive measurements by selected diameter.
