Core bit

Coring drill is mainly used for steel plate and other products drilling tools, hollow drill with specialized machine coring drill. Thin-wall diamond coring bit: concrete core sample is drilled directly on structural concrete, and the compressive strength test is carried out after processing the core sample. This method is recognized as a more intuitive and reliable test method for testing concrete strength. For coring method and technical operation, please refer to "Technical Specification for Testing concrete Strength by Drilling Core method" officially issued in China.

Hollow core bit and Drill Bit, mainly used for drilling tools for steel and other products, hollow drill with core bit on special machine, has the efficiency of fast, the characteristics of low cost, core drill bit blade is made of carbide end tooth geometry with three layers, brisk cutting, steel bit service life is long, the double smoothing handle interface, is suitable for the drill of the bell, etc. Carbide drill is also suitable for all kinds of vertical drilling machine, radial drilling machine, milling machine, lathe and so on.

Coring bit classification: according to the material alloy bit, tool steel bit. Alloy bits are mainly used for hard materials, while tool steel bits are usually used for soft materials. Tool steel is relatively cheap for these two types of bits. Price: the market price ranges from more than 100 to more than 200.
