Benefits of Steel body PDC bit
High Rate of Penetration (ROP): Steel body PDC bits are designed for aggressive cutting, often achieving significantly higher ROP compared to roller cone bits in suitable formations due to their shearing action.
Enhanced Durability: The robust steel body construction provides superior strength and resistance to impact and abrasion, making them highly durable in demanding drilling environments.
Optimal Hydraulics: Steel bodies allow for larger junk slots and optimized nozzle placement, leading to superior hydraulics that efficiently clear cuttings and cool the PDC cutters, preventing bit balling.
Repairability: Unlike matrix body bits, steel body PDC bits can often be repaired by re-brazing new cutters onto the body, potentially extending their service life and offering cost savings.

Customize Your Desired Steel Body PDC Bits
Cutter Layout and Density
We precisely customize the PDC cutter layout and density to match your specific formation’s hardness and abrasiveness. For softer, more ductile rocks, we can design for aggressive, high-ROP patterns. For harder, more interbedded sections, we optimize for durability and stability, ensuring efficient rock removal.
Blade Count and Profile
We tailor the number of blades and their profile to enhance bit stability and cuttings evacuation for your drilling conditions. More blades provide greater stability in challenging formations, while fewer, more aggressive blades excel in softer rock. Our design ensures optimal hydraulic performance and efficient debris removal.
Gauge Protection and Durability
We integrate advanced gauge protection features to ensure consistent hole diameter and extend bit life in abrasive environments. This involves strategically placing robust PDC cutters or diamond-enhanced inserts on the gauge pads, preventing premature wear and maintaining wellbore integrity throughout the drilling run.
Nozzle Configuration and Hydraulics
We fine-tune the bit’s hydraulic performance by customizing the nozzle count, size, and orientation. This optimization ensures efficient cleaning of the bit face, effective cooling of the PDC cutters, and superior removal of rock cuttings from the borehole, maximizing penetration rates and preventing bit balling.
what are steel body PDC bits?
Steel body PDC (Polycrystalline Diamond Compact) bits are a type of drill bit where the cutters are brazed directly onto a solid steel body.
Unlike matrix body bits, which use a tungsten carbide matrix, the steel body allows for more complex and aggressive bit designs, including intricate blade profiles and junk slots.
This construction provides excellent strength and ductility, making them resilient to impact damage. Steel body PDC bits are highly effective in drilling soft to medium-hard rock formations, offering high rates of penetration and good durability.
What is the difference between steel and matrix PDC bits?
PDC (Polycrystalline Diamond Compact) drill bits are broadly categorized into two main types based on their body construction: steel body and matrix body. The fundamental difference lies in the material and manufacturing process of the bit body itself, which in turn influences their performance characteristics, durability, and suitability for various drilling conditions.
Steel Body PDC Bits: These bits are manufactured from a solid piece of high-alloy steel, which is machined into the desired bit profile. The PDC cutters are then brazed directly onto the steel body.
- Advantages: Excellent impact resistance, ductile (less brittle), easier to repair/re-tip, allows for more complex and aggressive hydraulic designs with larger junk slots, and generally more cost-effective for multiple runs.
- Disadvantages: Less resistant to erosion and abrasion compared to matrix bodies, which can be a concern in highly abrasive formations, and may require hardfacing for wear protection.
Matrix Body PDC Bits: These bits are made from a tough, non-ferrous composite material, typically a tungsten carbide powder infiltrated with a metallic binder (e.g., copper alloy). The PDC cutters are embedded into this matrix during a high-temperature, high-pressure sintering process.
- Advantages: Superior erosion and abrasion resistance, making them ideal for drilling in highly abrasive formations, offer longer life in challenging environments, and maintain their gauge well.
- Disadvantages: More brittle and less resistant to impact damage, generally more expensive, and harder to repair or re-tip compared to steel body bits.
What is a PDC bit?
A PDC (Polycrystalline Diamond Compact) bit is a type of drill bit used for rotary drilling that features synthetic diamond cutters instead of rolling cones or traditional steel teeth. These cutters are made from extremely hard, thermally stable polycrystalline diamond layers bonded to a tungsten carbide substrate.
PDC bits drill by shearing and scraping rock, providing a continuous cutting action rather than a crushing one. This design allows for significantly higher rates of penetration and longer bit life in various geological formations, particularly in soft to medium-hard and even some harder, non-abrasive rocks.
Why do we use PDC?
PDC (Polycrystalline Diamond Compact) bits are widely favored in drilling operations due to their superior performance characteristics and cost-efficiency over the long run.
Higher Rate of Penetration (ROP): PDC bits drill by shearing rock, which is a more efficient cutting mechanism than the crushing action of roller cone bits in many formations. This leads to significantly faster drilling speeds.
Extended Bit Life: The extremely hard synthetic diamond cutters are highly resistant to wear and abrasion, allowing PDC bits to drill longer distances and achieve more hours on bottom compared to other bit types, reducing the need for frequent bit changes.
Reduced Drilling Costs: While often having a higher initial cost, their extended life and increased ROP lead to fewer trips out of the hole, less wear on other drilling equipment, and overall lower cost per foot drilled.
Versatility in Formations: PDC bits are effective in a wide range of formations, from soft and sticky clays to medium-hard shales, sandstones, and even some harder, non-abrasive rocks, making them a versatile choice for various drilling projects.
Smoother Drilling: The continuous cutting action of PDC bits often results in a smoother drilling operation with less vibration, which can prolong the life of the drill string and surface equipment.
What is the difference between PDC and PCD?
While often used interchangeably, especially in the drilling industry, PDC and PCD refer to slightly different things, with PDC being a more specific application of PCD.
Here are some differences between PDC and PCD bits in the following:
PCD (Polycrystalline Diamond): This refers to the superhard material itself. It’s a synthetic diamond material created by fusing together many microscopic diamond particles under extremely high pressure and high temperature, often with a metallic binder. PCD is known for its exceptional hardness, wear resistance, and thermal conductivity, making it an ideal material for cutting tools across various industries, not just drilling.
PDC (Polycrystalline Diamond Compact): This refers to a composite cutting element or “compact” that incorporates a layer of PCD bonded to a tungsten carbide substrate. This compact is then brazed onto a drill bit body (either steel or matrix). The tungsten carbide substrate provides toughness and strength to support the brittle diamond layer, allowing it to withstand the significant forces encountered during drilling operations. In essence, a PDC is a specific type of cutting insert made from PCD material.
