1 Presentation of rock drill bit

With the top quality of alloy steels imported from USA and the best carbides made in China , we produce all threaded button bits by hot press technology .

2.Materials and produce process details of rock drill bit

Materials- we use 45CrNiMoVA and YK05 Tungsten carbide to produce our taper drill bit, both are famous materials for drill bit produce in the world .Advanced technology---We produce our taper button drill bit with hot-pressing technology which is the best-advanced technology of producing taper button bit up to date .

Button bits should be reground when penetration rates drop or if the cemented carbide shows signs of damage
Fixed grinding routines often result in good working practices .
Bits for instance , can be examined and then reground after a specific number of holes , or at the end of the shift . Premature grinding is not necessarily uneconomical since less carbide needs to be ground off . It is better to regrind rather than reducing productivity due to damage .
Correct grinding adds considerably to drill bit service life . But equally important , it also enhances the performance of the entire drilling operation , especially hole straightness .
