Four-Wing Non-Core Drill Bit

Stable One-Piece Forged Steel Four-Wing PDC Non-Core Drill Bit

Product Overview & Description

The Four-Wing Non-Core Drill Bit from CZDRILL is a PDC drilling tool engineered for full-face rock breaking without core recovery. It is designed for water well drilling, geological exploration, anchor grouting holes, and shallow engineering applications where stable destructive drilling is required.

Built with a one-piece forged alloy steel body and premium PDC cutting elements, the Four-Wing Non-Core Drill Bit provides a balanced cutting structure with increased cutter coverage. Compared with a three-wing design, the four-wing configuration can provide additional stability and cutter density for suitable formations. REG, IF, and NC thread options are available to match common drill pipe systems.

Key Features & Advantages

• Four-Wing Cutting Structure: The four-wing layout provides a balanced cutting structure and increased cutter coverage across the borehole bottom.
• One-Piece Forged Alloy Steel Body: The integral steel body provides structural integrity for drilling under suitable torque and load conditions.
• Premium PDC Cutters: PDC cutting elements deliver continuous shearing action rather than relying only on crushing action.
• Full-Face Non-Core Drilling: Designed for destructive drilling where core recovery is not required.
• Stable Drilling Design: The four-wing arrangement is designed to support stable drilling in suitable formations.
• REG, IF, and NC Connections: Standard thread options are available to match common geotechnical and water well drill pipe systems.

Applicable Formations & Applications

The Four-Wing Non-Core Drill Bit is optimized for soft to medium-hard formations and selected alternating strata where increased cutter density and stability are beneficial. Final bit selection should be based on formation hardness, abrasiveness, drilling method, flushing medium, and borehole requirements.

• Suitable Formations: Clay, loess, silt, mudstone, shale, weathered sandstone, weathered limestone, gravel-bearing layers, and selected alternating soft-hard strata.
• Water Well Drilling: Suitable for selected water well and irrigation drilling applications.
• Geological Exploration: Used for non-core geological and mineral exploration drilling projects.
• Anchor Grouting Holes: Suitable for anchor support, grouting, and related shallow engineering holes.
• General Engineering Drilling: Used for non-core destructive drilling where a stable cutting structure is required.

Frequently Asked Questions

Q1: What is a four-wing non-core drill bit?

A: A four-wing non-core drill bit is a full-face PDC drilling tool designed to break formation material without recovering a core sample. Its four-wing design provides a balanced cutting structure with increased cutter coverage.

Q2: How is a four-wing bit different from a three-wing bit?

A: A four-wing bit generally provides more cutter coverage and a more stable cutting structure, while a three-wing bit generally provides wider fluid passages and larger cutting clearances. The best choice depends on the formation and drilling conditions.

Q3: Which thread connections are available?

A: CZDRILL can provide REG, IF, and NC thread options to match commonly used water well and geotechnical drill pipe systems.

Q4: What information is needed for a quotation?

A: Please provide the required bit diameter, formation details, thread connection, drilling rig type, flushing medium, and intended application. We will recommend a suitable bit configuration.
