PDC Core Drill Bits

Product Description

High-speed PDC core drill bits (be made of polycrystalline diamond compact, natural or synthetic diamond) are used in the fields of geological exploration and engineering-oriented to afford reliable data. PDC bit is a variety of face profiles, and different diamond set types enabling a cost-effective solution to be taken for most conditions.

Advantages of PDC Drill Bit

* Fast penetration

* Strong abrasion resistance

* Good performance for rock formations

* No special demands for equipment

* Long service life

Applications
High-speed PDC core drill bits are mainly used for drilling oil wells, gas wells, water wells, etc. We design and manufacture PDC bits with good performance in a variety of soft, medium and hard formations.
* Clay stone/ lignite/ siltstone/ sand: We design 3-5 blades, low density cutter placement, large groove. low cost, high speed.
* Mudstone: We have the experience to design the proper insert shape and tool orientation for high ROP and stable drill bits.
* Grave/ limestone/ shale/ clay/ stone/ tuff: Dome, reasonable tool orientation. drilling is smooth and fast.
