CUSTOM BIT SERIES
Custom Drill Bits
Task-specific tools for reaming, combined pilot-reaming, retrieval, and borehole cleanout, configured by equipment, formation, and project objective.
PDC Reamer
Engineering Advantages
- 01CONFIGURABLE CUTTER PROFILES
- 02GAUGE PROTECTION
- 03CONTROLLED BORE ENLARGEMENT
At a Glance
- Formation / Operating Conditions
- f ≤ 10
- Size Range
- Project-specific diameter range
Product Details
The PDC reamer is configured around the existing bore, target diameter, formation, drill-string connection, and available flushing capacity. Three product positions support comparison of cutter profile, body diameter, gauge protection, and waterway layout for controlled enlargement in mining and special drilling applications.
Combined Pilot-Reamer
Engineering Advantages
- 01INTEGRATED PILOT & REAMER
- 02STAGED BORE ENLARGEMENT
- 03CONTINUOUS CUTTINGS REMOVAL
At a Glance
- Formation / Operating Conditions
- f ≤ 10
- Size Range
- Project-specific pilot and reamer diameters
Product Details
The combined pilot-reamer integrates guidance and enlargement functions for staged or continuous reaming. Pilot diameter, reamer diameter, connection, cutter layout, and waterways are selected around the drilling sequence, equipment capacity, formation behavior, and the required relationship between the initial and final bore sizes.
Retrieval Bit
Engineering Advantages
- 01COMPACT RECOVERY PROFILE
- 02CONFIGURABLE ENGAGEMENT
- 03CONTROLLED DOWNHOLE ACCESS
At a Glance
- Formation / Operating Conditions
- f ≤ 10
- Size Range
- Project-specific size range
Product Details
The retrieval bit is engineered around the object to be recovered, its position in the bore, available clearance, bore diameter, and drill-string connection. Engagement features, internal passage, body profile, and flushing can be configured for dropped objects, broken tools, and other downhole obstructions.
Borehole Cleanout Bit
Engineering Advantages
- 01CONFIGURABLE CLEANOUT PROFILE
- 02BORE DIAMETER RESTORATION
- 03FOLLOW-ON WORK PREPARATION
At a Glance
- Formation / Operating Conditions
- f ≤ 10
- Size Range
- Project-specific size range
Product Details
The borehole cleanout bit is configured for wall cleaning, diameter restoration, and preparation before redrilling or subsequent operations. The cleanout profile, gauge, waterways, body diameter, and connection are matched to the original bore condition, target diameter, equipment capacity, and required follow-on work.
Model-to-Formation Match
Custom drill-bit selection begins with formation category and coefficient F, then confirms target diameter, recovery task, connection, and operating sequence.
