Frequently Asked Questions

1. What is the primary function of a bit adapter/coupling?

The bit adapter is used to connect extension rods. It transmits impact energy from the rock-drill piston and rotation torque into the drill string without loss, ensuring efficient drilling operations.

2. What materials are used in the manufacturing of these couplings?

These drilling tools are manufactured using high-quality Carbon Steel and 23crni3mo alloy to ensure maximum durability and resistance to high-impact environments.

3. How many blows per minute can these adapters withstand?

Our adapters are engineered to handle extreme conditions, capable of withstanding and transmitting up to 6,300 blows per minute from the piston continually.

4. Which thread sizes are available for order?

We offer a wide range of thread sizes including R25, R28, R32, R35, R38, T38, T45, T51, and various crossover combinations like R25-R32 or R32-T38.

5. What are the shipping and packaging options?

Products are securely packed in wooden cases or cartons to prevent damage during transit. The standard package size is approximately 30x30x30cm with a gross weight of 5kg.

6. What is the production capacity for bulk orders?

We have a high production capacity of up to 500,000 pieces per month to meet large-scale industrial requirements globally.
