1 Presentation of Rock Drilling Bits
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 , SST58 , SST68 , SGT60 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 .
We produce advanced technology --- cone drill round by hot
technology , is currently producing a conical round drill the most
advanced technology .
When carbide or decrease the permeability signs of damage , should
be re-grinding button drill
Fixed abrasive program usually brings good work habits .
For example , after checking the borehole, and drilling a number of
holes at the end of shift or reground . Premature grinding is not
necessarily uneconomic , because of less need for grinding carbide
. It is best to re-grind , it will not damage and reduce
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
.
