Technical Specifications
| Bit type | Concave fixed-cutter PDC drill bit |
|---|---|
| Industry-reference diameters | 50–300 mm examples across specialist supplier catalogs |
| Body and blade layout | Steel-body integrated or welded construction; blade/wing count by configuration |
| PDC cutters | Industrial PDC cutting elements; common 13, 16 and 19 mm references |
| Face profile | Concave center with application-specific gauge structure |
| Connection | API Reg or project-specific/custom thread by review |
| Fluid path | Waterways or nozzles arranged for cooling and cuttings removal |
| Formation guidance | Soft-to-medium formations; hard, highly abrasive or severely fractured ground requires review |
Final interface dimensions, selected configuration and supply scope are stated in the formal quotation or approved drawing.
Compatibility and Required Interfaces
Rig and circulation system
Rotary drilling setup
Confirm torque, RPM, feed/WOB, fluid type, flow and pressure.
Formation and operating parameters control cutter and hydraulic selection.
PDC Cutting and Connection Configuration
Concave fixed-cutter geometry
The recessed center, blade structure, PDC cutters, gauge and waterways work as one cutting system.
Buyer value
Can support tracking, self-cleaning and efficient rotary cutting in the intended formation.
Selection condition
Profile, cutters and hydraulics must be matched to the project; impact-prone ground requires review.
Application Scenarios
- Water-well and geothermal drilling
- Grouting, gas drainage and mining holes
- Soft-to-medium sedimentary formations after technical review
Confirm Before Ordering
Configuration Inputs
- Coreless/full-hole drilling role and required diameter
- Mating rod or sub connection with thread evidence
- Formation, target depth and hole-straightness requirement
- Cutter/body and circulation requirements plus rig torque/RPM/feed
- Quantity, destination, inspection and packing requirements
Operating Limits
- Confirm whether the drilling role is coreless/full-hole
- Hard, highly abrasive, severely fractured or impact-prone ground requires technical review
- Catalog diameter and cutter references do not prove current PerfoMax availability
- Final connection, cutters, body and fluid path are controlled by quotation/drawing

Frequently Asked Questions
What does the concave profile do?
A recessed center can support tracking and cutting-force distribution, but actual stability depends on the complete profile, gauge, cutter layout, rig and formation.
Is this a core bit?
This page is for a concave fixed-cutter PDC family and should be treated as coreless/full-hole unless the quotation explicitly defines an annular coring structure.
Which formations are suitable?
Concave PDC configurations are commonly discussed for soft-to-medium sedimentary formations. Hard, highly abrasive, fractured or impact-prone ground needs technical review.
What connection information should I provide?
Send the mating drill rod or sub thread standard, pin/box direction, gauge and shoulder dimensions, or a controlled drawing/current part number.
What is needed for a quotation?
Provide diameter, drilling role, formation, connection, body/blade preference, PDC cutter requirements, circulation method, rig parameters, quantity and destination.
Matched Drill String and Flushing System
A complete PDC drilling setup combines the rig, rotary drive, rod/sub connection, selected concave bit, formation-matched cutters and an adequate circulation system.
