3-Blade Spiral PDC Reamer
4145H Steel Body 3-Blade Spiral PDC Reamer for Pilot Hole Enlargement
Product Overview & Description
The 3-Blade Spiral PDC Reamer from CZDRILL is a hole enlargement tool designed for reaming pilot holes to the required final borehole diameter. It is suitable for horizontal directional drilling (HDD), water well drilling, foundation drilling, and selected engineering drilling applications.
Built with a high-strength 4145H steel body, spiral blade structure, and premium PDC cutting elements, the 3-Blade Spiral PDC Reamer provides a three-blade cutting layout for efficient hole enlargement. The spiral blade design helps guide cuttings movement during reaming, while the reamer diameter, pilot connection, rear connection, and cutter arrangement can be configured according to project requirements.
Key Features & Advantages
- Three Spiral Blade Structure: The three-blade layout provides a balanced cutting structure for pilot-hole enlargement.
- 4145H Steel Body: The high-strength steel body provides a durable platform for the reaming structure and PDC cutters.
- Premium PDC Cutters: PDC cutting elements provide continuous shearing action in suitable drilling formations.
- Spiral Cutting Layout: The spiral blade structure is designed to support cuttings movement during the reaming process.
- Custom Diameter Options: Reamer diameter can be produced according to the required final borehole size.
- Flexible Connection Options: Pilot and back connections can be matched to the customer’s drill string and rig system.
Applicable Formations & Applications
The 3-Blade Spiral PDC Reamer can be configured for selected soft to medium-hard formations. Final reamer selection should be based on pilot-hole diameter, target hole diameter, formation hardness, abrasiveness, drilling fluid, pullback force, torque capacity, and drilling method.
- Suitable Formations: Clay, loess, silt, mudstone, shale, soft to medium sandstone, weathered rock, and selected alternating strata.
- Horizontal Directional Drilling: Used for pilot-hole enlargement in HDD pipeline and utility installation projects.
- Water Well Drilling: Suitable for selected water well borehole enlargement applications.
- Foundation Drilling: Used for selected pile foundation and construction drilling projects.
- Engineering Drilling: Applicable to borehole enlargement for general engineering and geotechnical work.
