Concave PDC configuration family
This product family presents fixed-cutter PDC bits with a recessed central face and alternative wing arrangements. Use the face and side views to identify a configuration before specifying its dimensions and connection.
Choose the configuration within the family
A three-, four- or five-wing designation describes part of the layout. Compare the cutter positions, face profile, gauge and open flow paths as well. Those features should be reviewed together; wing count alone is not a performance or formation rating.
Define the selected size
Specify the required bit outside diameter, overall length, connection and mating drill-string reference. The order drawing should identify the chosen layout and supplied assembly. A family list of model numbers does not establish a continuous diameter range or interchangeable threads.
Compare related configurations
The four-wing concave page focuses on a four-wing non-coring configuration. The three-wing spiral page provides another face-and-body profile to compare. Use the PDC design guide to prepare a configuration brief and the quotation guide to compare equivalent specifications.
