Product Description
The 38 mm PDC cross bit equals 1.50 in and is intended for small directional or oil-and-gas holes in soft, medium, or consolidated formations. Because the filename explicitly contains PDC, the product is placed in the PDC category despite its cross-shaped face. The directional drilling archive provides the application context, while the consolidated formation archive identifies bonded rock suitable for stable shearing.
The media name supports a 38 mm diamond-PDC cross profile but does not identify body material, connection, or nozzle arrangement. Those fields remain blank. Inspect each cross arm for equal cutter exposure, secure composite elements, and full gauge before use. S323 is selected from the permitted PDC IADC list. The 38 mm diameter describes the cutting face; it is not evidence of an R38 thread or any API Reg connection. Clean the valleys between arms before judging cutter wear, because packed fines can conceal chips and create a false impression that the cross is uniformly loaded.
Use 2,000–10,000 lbf/in WOB and 60–300 RPM, introducing load carefully on the compact face. The 250–650 gpm PDC flow reference applies to an 8.5 in hole, so it is not assigned to this 1.50 in bit. Gravel is a firm limitation because loose clasts can strike the cross arms and interrupt continuous cutter engagement. General directional drilling terminology is available from ScienceDirect. If torque becomes erratic, reduce depth of cut and inspect the cutters rather than forcing the cross geometry. Note which arm carries the damage. Retain the damaged arm for review.
