Bit Adapters & Couplings

Carburized Semi Bridge Cross Over Coupling Adapters

Frequently Asked Questions

What is the main function of these drill couplings?

The primary function of these couplings is to transmit impact energy from the rock-drill piston and rotation torque into the drill string without energy losses.

What materials are used in the manufacturing process?

The couplings are manufactured using high-quality Carbon Steel and 23crni3mo material, processed through forging to ensure maximum durability.

What thread sizes are available for the couplings?

We offer a wide range of thread sizes including R25, R32, T38, T45, and T51, as well as various crossover combinations like R25-R32 or R32-T38.

How many blows per minute can these couplings withstand?

They are engineered to withstand and transmit up to 6300 blows per minute from the piston continually with high endurance.

What is the production capacity and lead time?

Our production capacity is approximately 500,000 PCS per month, ensuring a steady supply for large-scale drilling operations.

What kind of surface treatment is applied?

The products undergo a professional spray-paint surface treatment, available in colors such as red, black, yellow, and white for corrosion protection and identification.
