3. PDC ADVANTAGES
1. Force balanced, resist impact to the blade during high-speed drilling, to make bit work stable.
2. Plus wear knot section, reduce collision in the high-speed rotational vibration.
3. Patented matrix formulation, extended bit life.
4. Optimal hydraulic design, easy to move out the drill cuttings and cooling.
5. Equipped with back reaming Cutters.
6. The cutter is high performance to increase the ability of anti-impact and anti-abrasive
Steel body PDC bit for oil and gas drilling
PDC Drill Bit is mainly used to drill oil well,gas well,water well,etc.
We design and product specifie PDC Bit with good performance for each soft,medium and hard formation.
1. Clay stone/lignite/siltstone/sands:we design 3-5 blades with low density cutter placement,large slot.Low cost,high speed.
2. Mudstone :we have experience to design suitable blades shape and cutterdirection to get high drill speed and stalbe drill.
3. Grave/limestone/shale/clay/stone/tuff:round crown and reasonable cutter direction.Drill smoothly in good speed.
