etc,.
Usage:
The tapered
drill rod which is matched with taper chisel bit, taper cross bit
and taper button bit, is mainly used for rock drilling, blasting
holes and other drilling works in the quarries, coal mines, traffic
and other constructions.
A wide taper
degree is normally used when drilling with high impact hydraulic
rock drills in medium hard to hard and abrasive rock
formations.
Generally,
the light-duty rock drill uses 7 taper or smaller taper degree, the
heavy-duty rock drill mainly uses *2 taper degree.
The tapered
drill rods have a tough life, transferring the percussion energy
from rock drill to drilling bit and then into the rock. They are
also subjected to high bending stress, not to mention corrosive
water in the flushing hole.
It is
forbidden to keep working when the tapered drill rod is bended,
otherwise the service life of the tapered drill rod would be
decreased.
If the
tapered drill rod was sheared, it can be restored by re-machining a
new taper.
