摘要：
Reamers for use in core-sample drilling having PDC inserts and methods for using the reamers with PDC inserts are described. A reamer with PDC inserts may be used to maintain borehole diameters, reduce deviation, and/or stabilize drill strings used in core sample drilling. The PDC inserts may be of different sizes and shapes and may be arranged around the reamer in various ways.
