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 .
