SHANDIKE Top Hammer Drilling Tools for Drifting and Tunneling
Intraset
used for shaft sinking, tunnel driving and mining where small holes are desired.
Tapered Equipment
used in shaft sinking, tunnel driving and mining where small holes are desired. The objective in using tapered drill
steel and bits is to achieve the full utilization of the drill steel. With integral drill steel if the chisel wears or breaks the entire unit is discarded,whereas the tapered drill bits can be replaced or the steel reshanked or even retapered.
Rope Thread
used for underground mining in production drilling, longhole drilling, and roof bolting applications
Choosing the right carbide:
The larger the volume of carbide, the more aggressive the bit. The more aggressive carbides assist movement of the chips away from the face as there is more room for airflow on the face of the bit.These more aggressive bits help to break out larger chips, which increases the penetration rate.There is also a greater volume of carbide to wear away which can lead to longer bit life.
