Flat-Top 4-Wing Non-Coring PDC Bit

Flat-top four-wing configuration

The illustrated family uses a flat-top cutting profile and a four-wing PDC arrangement for non-coring drilling. The face and side photographs support comparison with concave and spiral layouts.

Flat and concave are separate choices

A similar wing count does not make a flat-top face equivalent to a concave face. Compare the central cutting coverage, cutter positions, gauge, ports and seating dimensions. The four-wing concave bit and the three-wing spiral bit provide related configurations to discuss.

Assembly and operating information

Provide the required outside diameter, connection drawing, hole depth and direction, ground description, rig and flushing method. The selected configuration should have its own operating guidance and inspection criteria.

Prepare the next order or trial

Record the model or drawing revision used, drilling interval, settings, returns and observed wear. Compare penetration and tool condition over a defined run, rather than substituting an unverified rate or bit-life figure for site evidence. See the PDC run-record guide and the water-well purchasing checklist.
