T38 T45 T51 hard rock drilling bits for quarry ,mining drilling
The United States imports of high-quality steel and best Chinese carbide manufacturing , we produce all thread button drill by hot pressing technique .
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 .
3 A comprehensive range of various button bits shown as below:
| Thread sizes | R25, R28, SSR28, R32, SSR32, R35,SST58, SST68, SGT60 ...... |
| Head diameters | 33mm ~ 152mm |
| Face designs | flat face, drop center, uni-face |
