Frequently Asked Questions
What shanks are compatible with these DTH bits?
Our bits are compatible with a wide range of shanks including CIR, DHD, M, QL, and SD adapters.
What materials are used in the manufacturing process?
We use high-quality Carbon Steel and Tungsten Carbide (Yk05 or T6 grade) to ensure maximum durability and wear resistance.
Do these hammers work with high-pressure rigs?
Yes, they are specifically designed for both low and high-pressure drilling rigs, providing excellent penetration rates.
What is the expected penetration speed increase?
Due to the advanced inner structure and energy delivery, these bits can penetrate 15% to 30% faster than standard alternatives.
Are the hammers easy to maintain?
Absolutely. The inner structure is simple and reliable, designed for easy assembly and disassembly to reduce downtime.
How are the products protected during shipping?
All drill bits and hammers are securely packed in robust wooden cases to prevent damage during transit.
