Misson Shank DTH Drill Bits M40-115mm Button Bit Match 4" Hammer
Misson Shank DTH Drill Bit M40-115mm Button Bit Match 4" Hammer
In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.
Mission shank DTH Button Bit
It is a kind of high air pressure DTH hammer without foot valve. It is also one of the most advancedDTH hammers in the world.
It has the following advantages:
1. Out of the trouble of foot valve fracture and expansion and contraction.
2. Lower energy consumption and higher impact frequency. The drilling speed is 15-30%higher than the one with foot valve.
3. Simple structure, reliable parts, long life span, easy and cheap maintenance.
4. Lower air and oil consumption. The oil consumption is about 10% lower than the one with foot valve.
