Designed for versatile application across all kinds of rock formations. 5. Choose from flat, concave, and convex bit face shapes to match your drilling requirements. 6. Equipped with spherical and ballistic buttons for diverse drilling needs. Features: 1. Premium and reliable quality ensuring long service life with minimal risk of breakage. 2. Efficient flushing effect guarantees a high drilling rate. 3. Adherence to strict quality warranties and compensation policies. 4. Thoughtfully engineered designs for optimal performance. 5. Exceptional penetration capability. Bit Face Shape Selection:1. Drop Center BitIdeal for achieving high penetration rates in soft to medium-hard fissured rock formations with low to medium air pressures. Offers superior hole deviation control.2. Concave FaceVersatile bit face suited for medium-hard, homogeneous rock formations. Provides excellent hole deviation control and superior flushing capacity.3. Convex FaceDesigned for high penetration rates in soft to medium-hard rock with low to medium air pressures. Notable for resistance to steel wash, reducing load and wear on gauge buttons, although it offers limited hole deviation control.4. Flat FaceIdeal for hard to very hard and abrasive rock formations, especially under high air pressures. Ensures good penetration rates and resistance to steel wash. Raw MaterialSteel:Manufactured using first-class special alloy steel known for its high strength, heat resistance, and wearability.CarbideTop-grade Chinese tungsten carbides are typically used.European tungsten carbides are also available on request.
