About Product

1,ZuanLong PDC hole opener was originally developed for coal mining and it has been proved to be exceptionally cost effective for geotechnical drilling.


2,PDC core bits have extremely fast penetration rates and a very long working life. The cutters are extremely tough and can core formations such as hard  limestones with occasional bands of harder rock such as ironstone.


3,The cutting action is extremely aggressive and a large volume of cuttings are produced requiring good volumes of flush to clear the hole and prevent blocking.


4,Recommended for coring soft to medium hard formations, with water, air, mud or foam as the flushing medium. Ideal for air flush applications where a high rate of production is required.


5,The size, number and layout of the cutters can be varied to suit the rock hardness, abrasivity and other details of the application
