PDC Core Bits is suitable for the strata of soft and medium-hardness such as mud stone, shale, sandstone, limestone, marble. It has a long working life, very fast penetration and high percentage core recovery in soft to hard rock formations. 

Characteristics
High wear resistance and impact-resistant toughness, long drilling life, drilling efficiency can be promoted sharply in penetration of soft medium and medium-hard formation, laber intensity can be reduced. 

This kind of PDC at high pressure and temperature, which is composed of diamond. It can be embedded into mine drill that used in medium-high hardness stratum drilling. 

The special shape and different technique make this PDC higher drilling speed, and especially suitable for siliceous rock, conglomerate.
