Audited Supplier | General Introduction |
1. Our DHD, COP, MISSION, QL, SD, and MACH shanks are designed to provide reliable quality and long service life. They are highly durable and rarely experience abnormal breakage during their service life.
2. The flat, concave, convex, and drop center bit face shapes offer versatility for various drilling needs. Whether you are dealing with soft, medium-hard, or fissured rock formations, we have the right bit face shape for you. Additionally, our spherical, ballistic, and semi-ballistic buttons ensure efficient drilling in different rock formations.
3. Our bits are suitable for all kinds of rock formations, making them a versatile choice for drilling projects.
4. We prioritize the flushing effect of our bits to ensure a high drilling rate. With our products, you can expect excellent hole deviation control and good flushing capacity, resulting in efficient drilling operations.
5. We have strict quality warranty and compensation rules in place to guarantee customer satisfaction. Our designs are carefully crafted to meet industry standards and provide optimal performance.
6. Our bits offer high penetration rates, allowing you to complete drilling tasks quickly and effectively.
1. Drop Center Bit: This bit face shape is ideal for achieving high penetration rates in soft to medium-hard and fissured rock formations. It performs well under low to medium air pressures and ensures maximum hole deviation control.
2. Concave Face: The concave face shape is suitable for medium-hard and homogeneous rock formations. It offers good hole deviation control and has a high flushing capacity.
3. Convex Face: If you need high penetration rates in soft to medium-hard rock formations with low to medium air pressures, the convex face shape is the right choice. It is highly resistant to steel wash and reduces the load and wear on the gauge buttons. However, it may have poor hole deviation control.
4. Flat Face: Our flat face shape is designed for hard to very hard and abrasive rock formations. It performs well under high air pressures, providing good penetration rates and resistance to steel wash.
