Product Description General Introduction1. Carefully crafted DHD, COP, MISSION, QL, SD, and MACH shanks.2. Meticulously designed Flat, Concave, Convex, and Drop Center shapes.3. Expertly formed Spherical, Ballistic, and Semi-Ballistic designs.4. Versatile application range: Suitable for all kinds of rock formations.5. Diverse bit face choices: Flat, Concave, and Convex.6. Precision-engineered Spherical and Ballistic buttons.Features:1. Unwavering reliability and quality, ensuring a long service life with rare occurrences of abnormal breakage.2. Exceptional flushing effect designed to guarantee a high drilling rate.3. Rigorously enforced quality warranty and compensation policies.4. Ingenious and practical designs.5. Outstanding high penetration capabilities.Bit Face Shape Selection:1. Drop Center BitExcellent for achieving high penetration rates in soft to medium-hard and fissured rock formations. Operates efficiently at low to medium air pressures with superior hole deviation control.2. Concave FaceAn all-encompassing application bit face, perfect for medium-hard and homogeneous rock formations. Provides excellent hole deviation control with superior flushing capacity.3. Convex FaceIdeal for high penetration rates in soft to medium-hard environments, functioning well with low to medium air pressures. Offers robust resistance to steel wash, potentially reducing load and wear on the gauge buttons, albeit with less than optimal hole deviation control.4. Flat FaceDesigned for hard to very hard and abrasive rock formations, especially in high air pressure applications. Ensures good penetration rates and strong resistance to steel wash. Raw MaterialSteel:Utilizes first-class special alloy steel with high strength, remarkable heat resistance, and superior wearability.CarbideUtilizes the finest tungsten carbides from China, renowned for their reliability and performance.Premium tungsten carbide from Europe is also available, offering diverse options to meet varied needs.
