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 production of tungsten carbide and YK05 our cone drill bit , these two materials 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 producing tapered round bit drills .
When the permeability decreased or carbide signs of damage , should be re-grinding button drill
Fixed abrasive program usually brings good work habits .
For example , after checking the drill , then drill a number of holes or reground at the end of the shift . Premature grinding is not necessarily uneconomic , because less need for grinding carbide . The best reground and not damaged and reduced productivity .
Correct grinding greatly increases the service life of the drill bit. But equally important , it also improves the performance of the entire drilling operation , especially straightness of the hole .
