Dual-tube coring configuration
This PDC core-bit family is intended for a matched dual-tube sampling assembly. Specify the cutting crown, core passage and inner and outer barrel interfaces together.
Keep the diameters separate
The source catalogue identifies a 94 mm product with an 89 mm core barrel. A barrel diameter is not the recovered core diameter. Confirm the bit outside diameter, crown opening, core size and barrel clearances against the assembly drawing before ordering.
Information for selection
Send the barrel make and model, a dimensioned connection drawing, formation description, sample requirements and flushing arrangement. The inner-tube material, liner, retention system and operating parameters belong to the selected assembly specification.
Use the core-bit ordering checklist or compare spiral PDC core bits in the core-drilling family.
