Impregnated Diamond Core Bit
Model:CORE
Selected configuration:Configuration to be confirmed
Selected reference:Configuration required
Impregnated diamond core bits configured by core system, OD/ID, matrix, crown, gauge and waterways.
Impregnated diamond core bits for mineral exploration and geotechnical coring, selected as a complete core-system configuration rather than by matrix number alone.
- Diamond-in-matrix crown for annular core cutting
- Matrix, crown, gauge and waterways selected together
- Core-system and operating inputs controlled before quotation

Technical Specifications
| Bit type | Impregnated diamond annular core bit |
|---|---|
| Core-system reference | B-, N-, H- and P-class wireline systems are common inquiry families |
| Dimensional inputs | Bit OD, bit ID/core diameter, kerf, gauge and connection |
| Matrix selection | Supplier-controlled matrix series selected for ground and operating conditions |
| Crown configuration | Profile, height and impregnation depth by approved design |
| Waterways | Type, count and width selected for fluid delivery and cuttings removal |
| Gauge relationship | Bit gauge and matched reaming-shell gauge controlled as one system |
| Operating inputs | Lithology, hardness, competency, abrasivity, fractures, depth, RPM, feed and flushing |
Final interface dimensions, selected configuration and supply scope are stated in the formal quotation or approved drawing.
Compatibility and Required Interfaces
Reaming shell and fluid system
Matched gauge and flushing arrangement
Control bit gauge relative to reaming shell and confirm waterway/fluid capacity.
Current wear and core-recovery history should be included.
Configuration and Performance
Matrix-crown-system selection
Diamond size/concentration, matrix wear behavior, crown profile, gauge and waterways are selected with the core system and ground.
Buyer value
Supports a controlled balance of penetration, crown renewal, gauge retention and core recovery.
Selection condition
No single matrix or crown design is universal; the approved configuration governs.
Application Scenarios
- Mineral exploration coring
- Geotechnical and geological investigation
- Wireline and conventional coring systems after interface confirmation
Confirm Before Ordering
Configuration Inputs
- Exact core barrel, rod and reaming-shell system
- Bit OD, ID/core diameter, connection and gauge relationship
- Matrix/crown/waterway reference or current supplier code
- Lithology, abrasiveness, fractures, depth, RPM/feed and fluid
- Core-recovery objective, quantity, destination and packing requirements
Operating Limits
- Core-system size, barrel, rod and reaming shell must be identified together
- Matrix numbers and colors are supplier-specific and not directly interchangeable
- No single matrix, crown or waterway suits every formation
- Final dimensions and construction are controlled by quotation/drawing

Frequently Asked Questions
What is an impregnated diamond core bit?
It uses diamond particles distributed through a metal matrix crown and cuts an annulus so a core can be recovered.
Which core-system information is required?
Identify the barrel and rod system, size, connection, bit OD/ID, matched reaming shell and any current supplier code or drawing.
Can matrix numbers be compared directly between suppliers?
No. Matrix numbering and color systems are supplier-specific. Provide the current code as a comparison reference, then use the approved PerfoMax configuration ID.
How are crown and waterways selected?
They are reviewed with the matrix, core-system dimensions, formation, fluid, depth, RPM/feed and required core recovery or sample integrity.
How is this different from a PDC coring bit?
An impregnated bit uses diamond particles within a metal-matrix crown; a PDC coring bit uses discrete PDC cutters. Their cutting structures and selection controls are different.
Required Matching Components
A complete coring system combines the rig, rods, core barrel, impregnated bit, matched reaming shell, core lifter components and adequate fluid delivery.
