Steel Body PDC Drill bits

Steel PDC
Steel Body PDC has a number of advantages with their compact malleable steel unibody construction.
1. Reduced makeup length for improved build rates and directional response
2. Maximum face volume and junk slot area combined with optimized nozzle placement clear cuttings efficiently in long laterals or low flow.
3. Updrill cutters for improved side cutting and additional gauge protection.
4. Proprietary tungsten carbide spray metal technology for maximum erosion resistance and superior toughness in demanding applications.
5. Sintered carbide nozzle bore sleeves prevent internal erosion.
6. Domed inserts for reduced vibration and improved toolface control.
7. The latest in PDC cutter technology for superior abrasion and impact properties.  
Polycrystalline diamond compact (PDC) bits were first introduced into the oil industry in the mid 70's. Since then, numerous technological design changes have been implemented that have made them an extremely effective tool when drilling in
certain formations, most typically homogenous sedimentary rock formations including sandstone, shale, dolomite, and limestone. PDC bits use a shearing or shaving action when encountering the formation. These bits are normally used at higher rotation speeds than typical rotary bits. 
The hydraulics of PDC bits are designed to keep the hole clean and the bit cool, which in turn increases the ROP and longevity of the bit.  
ROSCHEN offers a wide range of PDC bits in sizes up to 24".  All PDC bits are fully customizable to meet specific drilling requirements, depending on the formation being drilled and the equipment being used.

Body: 

Steel body PDC bits are a lower cost alternative, to matrix body bits. They are generally preferred in soft formations, such as sandstone.Matrix body PDC bits provide excellent resistance to wear. They are commonly used in harder more abrasive formations such as limestone and dolomite. 

Number of Blades: 

The number of blades on a PDC bit is largely determined by the formation being drilled. Generally higher blade and cutter counts are used for harder formations, whereas in softer formations fewer blades can be used to increase ROP. Gauge protections is applied to all bit blades to insure longevity and to sustain a straighter hole which increases ROP. 

Cutter Characteristics (count and size): 

Cutter count and size can be adjusted for drilling in specific formations. Small cutters and high cutter count are chosen for hard and abrasive rock formations, whereas large cutters and a reduced cutter count are preferred for soft to medium formations.   

Hydraulics:  

PDC bits are available with flushing holes or open center and either fixed or adjustable nozzles. Options are available for all varieties of PDC bits and are designed specific to those PDC bits to maximize bit performance and longevity.
