Introduction

In the pdc drill bits market, there are many pdc drill bits companies, but Roschen Group owned Global pdc drill bits manufacturers, we make many different rock drilling tools, like Roller Tricone Rock Bits, Hole Opener, Single Cone Roller Bits, PDC Bits, Diamond PCD Tricone Drill Bits, DTH Drilling Tools, such as DTH hammers and bits, DTH drill pipes, RC hammers and bits, tophammer button bits, coupling, cross bits, drill rods located in Germany, China(joint-venture).

Good pdc drill bits definition, Standard bits can be easily disrupted by the dynamic instabilities of directional or lateral drilling, but ROSCHEN steel body PDC drill bits feature discontinuous seven-blade bit design to address these factors with improved performance just like atlas copco pdc drill bits, baker hughes pdc drill bits. 

Roschen used proprietary software to model how the bits function under a variety of drilling challenges such as rotating off center axis and abnormal force absorption. COMMANDER PDC Bit Series demonstrated up to 35 percent improvement in stability in off center axis drilling situations with a 29 percent improvement in stability for abnormal force absorption.

Finding a bit that offers both good steerability and good ROP can be a difficult proposal. In theory, more blades offer more stability and by extension better ability to control and steer the bit. However, more blades typically also means more cutter contact with the formation, which equates to slower drilling.

Owing to high quality, professional serivce and competitive price, we have gotten good reputation from our customers from all over the world, such as US, Canada, France, Spain, Italy, South Africa, South Latin Amercia, Brasil, Saudi Arabia, UAE, Iran, Malaysia, Australia, etc.

We have all kinds pdc drill bits for sale and rich experience in this field of Roller Tricone Bits, PDC Drill Bits, Oil Drilling Toosl, Rock Drilling tools, DTH hammers and bits for 60 years. We can give you competitive pdc drill bits price with good performance.

production process

How pdc drill bits are made?Heat generated by friction during the drilling process can causes cobalt in the cutters to expand at a higher rate than diamond. Thermal stress in the diamond table increases until the structure breaks down. The cobalt between the diamond crystals expands and breaks the diamond-to-diamond bonds. The result is reduced cutter life and premature cutter failure.

That is the security pdc drill bits, Patent protected deep-leaching technology selectively removes cobalt from the diamond table of the PDC cutter. Leaching increases cutter thermal stability, which reduces damage to the cutter and extending bit life in difficult and abrasive formations.

Pdc drill bit manufacturing process

Pdc drill bit manufacturing process

Starting with a standard cutter, the diamond table is removed from the substrate. The substrate is discarded and cobalt is removed from the diamond table. The diamond table is then attached to a new substrate. The resulting PDC cutter is deep leached, removing infiltrated cobalt to several hundred microns.
