Steel PDC Bit With High Performance For Well Drilling

1. The Steel PDC bit is a one-piece bit, and the bit parts should not fall off during drilling, so it can be used at a higher speed and can withstand greater lateral load without downhole accidents.

2. Steel Body PDC bit mainly relies on the cutting action of the PDC composite piece to break the rock, with low torque and good stability during drilling, and high mechanical drilling speed under smaller drilling pressure and high rotational speed.

3. Steel PDC bits are wear-resistant and long-lasting when used correctly, and are suitable for deep wells and abrasive formations.

What Steel PDC Bit can DrillMore provide?

DrillMore mainly provide PDC bits from size 51mm(2") to 216mm(8 1/2"), with 3/4/5/6 wings which is widely used in natural gas drilling and deep wells.

Advantages Of Steel Body Over Matrix Body PDC Bits

The entire body of the Steel PDC Bit is made of medium carbon steel and machined.The PDC cutting teeth are fixed to the crown of the drill by means of a pressure fit. The crown of the bit is surface hardened (sprayed with tungsten carbide wear layer, carburized, etc.) to increase its resistance to erosion. The main advantage of this type of drill bit is the simplicity of the manufacturing process. Steel Body Bits have a larger chip flute area, higher flank height and narrower flank thickness than tire body bits.

DrillMore produces Steel Body PDC bits with tungsten carbide dressing wear layer, which enhances the wear resistance and erosion resistance of the steel body PDC bit flanks; improves the hydraulic performance for drilling in soft strata, resulting in better chip evacuation; enhances the protection of cutting teeth; improves the reliability and erosion resistance of the bit; and combines the advantages of tire body bits and steel bits to increase the mechanical drilling speed.

The drill head is treated with the surface hardening process (spraying tungsten carbide wear -resistant layer) to enhance its erosion resistance. The advantage of steel body is that the manufacturing cost is low and easy to repair.
