Application:
TheD*4mm *2 Taper Rock Chisel
Drill Bits are widely
applicable to mining industry, tunneling and underground engineering,
open pit, construction drill, blast
industry, civil engineering operations, road,gas
line, pipe and trench projects, quarry work, rock anchoring and
ground stabilization projects, water well industry, etc,.
Usage:
Advantages oftaper drill bits:Cheap in
price and theassorted
taper drill rods and rock drills, easy to carry and adequate for
various construction conditions. Matched with taper drill rods,
the taper drill bits
are widely used in drilling holes
with depth less than 5 meters and diameter ranged in ****6 mm by
light-duty rock drill.
Each oftaper drill bit is produced in different sizes and designs in
order to optimize their application to a broader scope of rock
drilling conditions and correspond to different job
requirements.
There are different taper degrees
fortaper drill bit
which are used for different rock
formations and rock drills.
Taper degree of *1°and *2° are
common on modern rigs. A narrow taper degree of 7° is used for
low impact rock drills and softer rock formations. This degree
can also be used if you have spinning problems when using *1° or
*2° equipment.
To ensure the normal service life,
thetaper drill
bitneed to be matched well
with taper drill rods, the taper degree must be the same between
taper drill bits and taper dill rods; the penetration depth of
taper drill rods which into the taper hole of taper
drill bits should be over *5mm,and the
head of the taper drill rods should not touch the bottom of the
taper of taper drill bits, otherwise the taper drill bits would
be lost easily during operation.
The operation for rock drill is
also important: before starting drilling, turning down
the air flow level of rock drill to reduce the damage to the
taperdrillbits
which is resulted from the local high stress suffered by the
tungsten carbide. The taper bits should fully penetrated into
rocks before turning up the air flow back to the normal
level,
When the width of the edges flat
top is more than 3 mm, its
necessary to change or grind the
taperdrill
bits in order to avoid low drilling
speed and short service life time of
taper drill bits. Once there is abrasion for the taper
onrock drill bits, change or grind
therock drill bits timely, otherwise
therock drill bits would be seriously worn, drilling
speed would be lowered and the taper drill bits would even
jammed.
Once encountering a steel bar or
other foreign materials during drilling, the drilling position
should be adjusted to avoid breakage of the head of
rockdrillbits.
When the rock drilling is prone to
jamming, the rock bits should be replaced to taper cross drill
bits or taper bits.
