High quality R32 , R38 , T38 , T45 , T51button rock drilling bits
for mining and quarry
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 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 --- We produce
cone drill bit using the best hot button cone bit production of
advanced technology .
When carbide or decrease the permeability signs of damage , should
be re-grinding button drill
Fixed grinding program usually brings good work habits .
For example , check bits , and then again at the shift end milling
or after a certain number of holes . Premature grinding is not
necessarily uneconomic , because less needs worn carbide . It is
better to re-grind rather than reduce productivity due to damage .
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
.
