Arc base：The curved crown scraper cutting structure, staggered tooth arrangement, ensures sharp cutting teeth, and has the characteristics of high stability, fast drilling speed, and long service lifeMatrix type：The sintered WC matrix is embedded with diamond polycrystals, which endows the drill bit with strong wear resistance, impact toughness, and diameter retention performance. The cutting teeth use oil PDC cutters.Mainly used for complex and highly abrasive formations and directional hole drilling, with extremely high drilling speed and long drill life
