NDS Drilling Supply

Polycrystalline Diamond Compact (PDC) bits are designed for consolidated sedimentary rock formations such as sandstone, limestone, and shale, and are available on NDS’s Online Store. Using durable diamond cutters, PDC bits shear through rock formations rather than grinding and crushing them like tricone bits. With no bearings, PDC bits experience reduced bit failure, allowing them to drill thousands of feet and significantly lower your cost per foot. However, caution should be used when drilling in unconsolidated formations that may contain gravel, boulders, or fractured rock, as these conditions can easily damage the brittle diamond cutters.

NDS stocks a complete line of PDC Bits with three to eight blades depending on the hardness of your formation.  Listed Below are several common sizes we stock or can ship out in one to two days!
