High quality tungsten carbide T6 and YK05 rock drilling bits for
mining, tunnel
1 Product description of Rock Drilling Bits
We use our 45CrNiMoVA material to produce tungsten carbide and YK05
tapered drill bits, both of which are world-renowned drill bit
production materials.
Advanced technology - we produce cone drill thermal technology,
which is currently producing cone drill bit of the most advanced
technology.
When carbide or decreased permeability signs of damage, should be
re-grinding button drill Fixed grinding program usually brings good
work habits.
For example, check bit, end mill or milling then move again after a
plurality of holes. Premature grinding is not necessarily
uneconomic, because less need to wear carbide. The best reground,
it will not be 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.
Taper taper drill drilling is the most common, which head diameter
ranging from 48mm to 26mm. Sector skirt carbide drill using hot
pressing, fine cone drill fan performance and long service life.
