Product Description
This 160 mm three-blade PDC bit converts to 6.30 in and is positioned for directional or oil-and-gas drilling in soft, medium, or consolidated formations. The stepped three-blade profile places diamond-composite cutters on separated wings, leaving open paths for cuttings between them. Review compatible work in the directional drilling archive and compare rock limits in the consolidated formation archive. The bit is supplied as a new, made-to-order product family.
The filename identifies a 160 mm PDC step bit with three blades but does not state whether the supporting body is matrix or steel. That field remains blank rather than being guessed. Inspect cutter exposure, blade symmetry, gauge condition, and the connection before use. M323 is recorded as the permitted PDC IADC value for this reviewed item. The connection also remains unclaimed because none of the allowed API Reg sizes is encoded in the source filename. Confirm that the step heights are even around the face, since one damaged blade can load the remaining cutters and distort directional response.
Use the approved PDC envelope of 2,000–10,000 lbf/in WOB and 60–300 RPM. The 250–650 gpm flow range applies specifically to an 8.5 in reference hole, so it is not copied into this 6.30 in product specification. Select actual hydraulics from the supported assembly and observed cleaning. This bit is not suitable for gravel, where loose clasts can interrupt stable shearing and strike the cutters. General drilling concepts can be checked through PetroWiki. Reduce cutter engagement when torque rises sharply rather than forcing the three blades.
