Threaded cross-type drill bits and threaded X-type drill bits are commonly used in very hard and stony rock formations. Our company provides the following specifications and models of cross-type drill bits: Thread model：R25, R28, R32, R35, R38, T38, T45,

Easy return threaded cross drill bits are commonly used in very hard and rocky rock formations. Thread model：R25, R28, SSR28, R32, SSR32, R35, SSR35, R38, T38, T45, T51.   Drill diameter：38mm ~ 152

Drill bits, especially taper tooth bits with a drill diameter of 26 mm to 48 mm, are used a lot. The alloy tooth is embedded in the drill bit reservoir using the hot setting process, so that the taper column tooth drill bit can have good drilling performance and long working life. Our comp

Expanding drilling tools are often used when the diameter of the drilled hole needs to be increased when reaching the drilling depth. Available with combined pilot reaming bits, mushroom reaming bits and combined reaming bits. Thread model: R28, SSR28, R32, SSR32, R35, SSR35 Pilot d

As one of the reaming drilling tools, the mushroom type column tooth drill bit is often used when the drill bit needs to be enlarged after the pilot drill bit is drilled to a specified depth. Thread model：R28，SSR28ï

The use of computer numerical control machine tools and high-quality steel to produce the connecting sleeve to ensure the reliability and controllability of product quality. Thread model：R22，R25，R28

The shank adapter is used to transfer the energy of the drilling rig to the important connection part of the drilling tool, which can generally be divided into two types: male and female. Among them, male thread adapter is more widely used than female thread adapter. The male thread adapter is su

Our hexagonal drill pipes are made from the same steel as Sandvik and are produced on CNC machines using an international heat treatment process. We offer a complete range of hexagonal drill pipes as shown below. Thread Model：R22, R25, R28, SSR28, R32, SSR32, R3

The same steel is used as Sandvik and is produced on CNC machines using an international heat treatment process. We offer a full range of adaptors with different threads and lengths. Thread model：R32, R38, T38, T45, T51 Rod body specifications: round 32,

Integral carburizing taper brazing is to increase the carbon content of the surface layer of taper brazing through the carburizing process, thereby improving the surface hardness and overall strength and increasing the service life of taper brazing. Compared with conventional taper drilling, the
