📝 Product Description

Extension rods are manufactured using high-quality hollow drill steels. These rods are essential components in drilling operations, available in two primary shapes: Round type and Hexagonal type.

⚙️ Flushing Hole for Water/Air

⚙️ Male-Male & MF Rod Types

⚙️ Versatile Thread Connections

The integrated hollow hole, commonly referred to as a flushing hole, is specifically designed for transmitting water or air during the drilling process. The precision-engineered threads allow for seamless connection with couplings, shanks, or drill bits.

Technical Range:

❓ Frequently Asked Questions

What materials are used for your extension rods?

Our extension rods are manufactured from high-grade Carbon Steel and 23crni3mo D6a hollow drill steel to ensure durability and high performance in demanding drilling environments.

What thread types do you provide?

We offer a wide range of thread options including R22, R25, R28, R32, R38, T38, T45, T51, ST58, and T60 to compatible with various drilling equipment.

What is the purpose of the hole in the center of the rod?

The hollow center, or flushing hole, is used to transmit water or pressurized air to the drill bit to flush out debris and cool the equipment during operation.

Can I get custom lengths for the extension rods?

Yes, while our standard lengths range from 600mm to 6400mm, we can provide various lengths between 0.4m and 6m to meet your specific project requirements.

What shapes are available for the extension rods?

We primarily manufacture two shapes: Round type and Hexagonal (Hex) type. Hexagonal rods are particularly useful for applications requiring higher rigidity.

How are the products packaged for international shipping?

Standard packaging involves secure wooden cases or tightly bound bundles to ensure the rods are protected from damage and corrosion during transport.
