PDC Bit

PDC bits are designed for high speed drilling in shale, limestone, and sandstone formations. Unlike roller cones, these PDC bits are a one piece matrix bodies with no moving parts. The fixed-cutters shave away the rock, making it possible to operate with higher rotation speeds more efficiently in consolidated formations.
