Application: The*0mm Low Air Pressure Down The Hole DTH bit with
Ballistic Button iswidely
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: Type of Buttons: Semispherical button: This type button is suitable for very
abrasive and very hard rock formations, it’s usually used as gauge
buttons of DTH bits. Ballistic button / Parabolic
button: This type button is suitable for medium
abrasive and hard rock formations, it’s usually used as gauge
buttons and front buttons of DTH bits. Conical button: This type button is suitable for medium
abrasive and medium hard formations, it’s usually used as front
buttons of DTH bits, If the rock is soft, it can be also used as
gauge buttons.
The
selection of Bit Face Type: Drop center face bit: It
has high penetration rates in soft to medium hard and fissured rock
formation, and has better hole deviation control. Concave face bit: It’s suitable for medium hard and similar
rock formations, it has good hole deviation control and good
flushing capacity. Convex face bit: It
has high penetration rates in soft to medium-hard rock formation.
It has the best performance of resistance to steel wash, and reduce
the load and wear on the gauge buttons, but it has poor hole
deviation control. Flat face bits: It’s suitable for hard to very hard and
abrasive rock formations.
