1 Product description of Rock Drilling Bits

Materials and produce process details :

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 .

Grinding cone drill holes is the most popular cone drill bit having a head diameter selected from a variety of 48 mm to 26 mm . With carbide drill thermocompression scalloped skirt portion , the tapered scalloped drill bit having good properties and excellent in life .
