PDC CORE BIT SERIES
PDC Core Bit Series
Core-bit structures for geological coring and representative sampling applications.
Single-Cutter Core Bit
Engineering Advantages
- 014 / 6 / 8 CUTTER OPTIONS
- 02STABLE CORING TORQUE
- 03CORE ENTRY & FLUSHING
At a Glance
- Formation / Operating Conditions
- f ≤ 10
- Size Range
- Project-specific size range
Product Details
The single-cutter core-bit family groups four-, six-, and eight-cutter configurations for direct comparison. Cutter count, crown geometry, connection, and flushing layout can be selected around formation behavior, target bore diameter, sampling objectives, and the required balance between penetration and core recovery.
Ribbed Core Bit
Engineering Advantages
- 01STABLE CUTTING CONTACT
- 02LATERAL CORE GUIDANCE
- 03OPEN CORE FLUSHING
At a Glance
- Formation / Operating Conditions
- f ≤ 10
- Size Range
- Project-specific size range
Product Details
The ribbed crown combines guided cutting contact with lateral support around the core entrance. Its passages are arranged to maintain flushing and remove cuttings while the crown, connection, and rib geometry can be configured for the intended formation, bore diameter, and core-recovery objective.
Double-Row Cutter Core Bit
Engineering Advantages
- 01DOUBLE-ROW CUTTER ENGAGEMENT
- 02STABLE CROWN LOADING
- 03DEPENDABLE CORE ACCESS
At a Glance
- Formation / Operating Conditions
- f ≤ 10
- Size Range
- Project-specific size range
Product Details
The double-row cutter layout distributes cutting contact across two working rows to support stable crown loading and controlled material removal. Core entry, flushing passages, cutter quantity, and connection can be matched to formation abrasiveness, target diameter, penetration requirements, and sampling priorities.
Inner- and Outer-Cutter Core Bit
Engineering Advantages
- 01SEPARATED CUTTING PATHS
- 02BORE-WALL CONTROL
- 03DUAL-INTERFACE FLUSHING
At a Glance
- Formation / Operating Conditions
- f ≤ 10
- Size Range
- Project-specific size range
Product Details
The inner- and outer-cutter arrangement separates the cutting paths along the core side and bore wall to support consistent geometry and core integrity. Cutter quantity, crown profile, flushing passages, connection, and diameter can be matched to formation behavior and the required sampling program.
Impregnated Diamond Core Bit
Engineering Advantages
- 01SELF-RENEWING DIAMOND MATRIX
- 02ABRASIVE ROCK PERFORMANCE
- 03CONTINUOUS CORE RECOVERY
At a Glance
- Formation / Operating Conditions
- f ≤ 10
- Size Range
- Project-specific size range
Product Details
The impregnated diamond crown uses a distributed diamond matrix that exposes new cutting points as the matrix wears. This structure supports continuous coring in abrasive medium-hard, hard, and very hard formations, with matrix grade, crown geometry, waterways, and connection selected for the operating program.
Surface-Set Diamond Core Bit
Engineering Advantages
- 01DEFINED DIAMOND CUTTING POINTS
- 02CONTROLLED ROCK ENGAGEMENT
- 03OPEN COOLING WATERWAYS
At a Glance
- Formation / Operating Conditions
- f ≤ 10
- Size Range
- Project-specific size range
Product Details
The surface-set diamond crown places defined diamond cutting points across the working face for controlled rock engagement and dependable core recovery. Diamond size, exposure, crown geometry, waterways, and connection can be configured around formation hardness, abrasiveness, drilling parameters, and the required sample quality.
Model-to-Formation Match
Use formation category and Protodyakonov coefficient F as the first selection layer, then confirm crown, connection, and sampling requirements.
