Product Description: JCDRILL thread button drill bits are made by high quality alloy steel bar and tungsten carbides. Through heat treatment, our drilling tools are tough enough to meet rock drilling demands and have the least loss of energy while drilling the rocks. Besides, we can design customized thread button drill bits according to different drilling application, and custom drill bits are applicable to drill soft rock, loose-medium rock and hard rock. Rock Drill Thread Button Bits is suitable for R22, R25, R28, R32, R35, R38, T38, T45, T51, ST58, T60 rock drill rods use. It have many thread. It's widely used for hard rock(f=8~18) drilling use. Our button bits diameters are from 32mm to 193mm, and different type are available, such as tapered type and threaded type. Excellent drilling penetration,Used in hard rock formation,Adequate for various construction conditions,Strong corrosion resistance 1) Thread connection: R22, R25, R28, R32, R35, R38, T38, T45, T51, ST58, GT60 2) Alloy steel:42CrMo 3) Suitable carbide tips:YK05 4)Technology:hot-pressing or welding Before Official Order, please confirm below informations: (1) Thread Type (2) Standard or Retrac (3) Bit button shape (tip shape)--Spherical or Ballistic (4) Bit face shape--Drop Center, Flat Face, Convex, Concave, etc...
