These optional features allow operators to select a matrix body PDC bit that is closely tailored to their specific drilling needs, optimizing performance and cost-effectiveness in a wide range of drilling environments.
Our matrix body PDC bits are widely used in:
Oil and gas well drilling
Water well drilling
Geothermal drilling
Mining exploration
HDD trenchless engineering
Geological and hydrological projects
Recommended formations:
Medium to hard sandstone
Limestone and dolomite
Shale with abrasive layers
Interbedded formations
Follow these steps for optimal selection:
Analyze formation characteristics: hardness, abrasiveness, interbedding (use IADC formation classification)
Review well parameters: depth, temperature, pressure, expected ROP targets
Match rig capabilities: rotary speed range, pump pressure & flow rate
Balance priorities: maximum bit life vs highest penetration rate

Matrix body bits are made from tungsten carbide material, offering higher durability and wear resistance in abrasive formations. Steel body bits, constructed from steel, are more flexible and less expensive, suitable for less abrasive and softer formations. Each excels in different drilling conditions.
Feature | Matrix Body PDC Bits | Steel Body PDC Bits |
Body Material | Tungsten carbide matrix | High-strength alloy steel |
Wear Resistance | Excellent | Good |
Erosion Resistance | Excellent | Moderate |
Impact Resistance | Moderate (less impact tolerant) | Excellent |
Repairability | Limited (difficult to rebuild, usually replaced as a whole) | High (easy to weld or rebuild) |
Temperature Tolerance | Higher | Moderate |
Best Suited For | Abrasive, hard formations | Soft to medium, high-impact formations |
Typical Bit Life (abrasive) | 1.5–3× longer than steel body (depending on formation) | Shorter in abrasive conditions |
