2 Materials and produce process details of T38 T45 T51 GT60 button Rock Drilling Bits

Material-We use 45CrNiMoVA and YK05 tungsten carbide to produce our tapered drills , both of which are world-renowned drill production materials .

Advanced technology---The tapered round bit drills we produce use hot pressing technology , which is currently the most advanced technology for the production of tapered round bit drills .

When the permeability drops or the cemented carbide shows signs of damage , the button bit should be reground
A fixed grinding program usually leads to good working practices .
For example , the drill bit can be inspected and then reground after a certain number of holes or at the end of the shift . Grinding too early is not necessarily uneconomical , because there are fewer carbides that need to be ground off . It is better to re-grind rather than reduce productivity due to damage .
Correct grinding greatly increases the service life of the drill . But just as importantly , it also improves the performance of the entire drilling operation , especially the straightness of the hole .
