IADC517/537 Tricone Pilot Reamer Diamond PDC bit Hole Opener For Oil Rigs
Introduction
PDC or "PAX" core bits utilise large cylindrical shaped cutters that consist of a layer of micron-sized synthetic diamond particles mounted onto a tungsten-carbide backing substrate (PDC = polycrystalline diamond compact).
The technology was originally developed for oil drilling bits. PDC core bits have proved to be exceptionally cost effective for geotechnical drilling.
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.
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.
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.
The size, number and layout of the cutters can be varied to suit the rock hardness, abrasivity and other details of the application
PDC drill bit used to penetrate the degassing hole, drain hole, and grouting hole of coal mine, water canservancy and hydropower, road construction, bridge and building.
