SP780 product description
The SP780 tailpipe-less high-pressure down-the-hole hammer has the advantages of fast action, large impact power, low gas consumption, and long life. It is widely used in geotechnical engineering to drill various medium-hard and high-hard tough rocks with poor drillability.
Advantages of SP780 high wind pressure hammer:
No tailpipe design
The drill used in this hammer has no tail tube, which eliminates the damage caused by thermal expansion and contraction of the hammer bit during work and during transportation, and improves the experience of using the hammer.
This down-the-hole hammer can be used in engineering construction such as mines, marble, quarry blasting, and water well drilling in conjunction with down-the-hole drills and down-the-hole drill bits.
The impact frequency of this hammer is faster than the same period last year, and the drilling speed is more than 15% faster. Compared with the same period, the piston is thinner, the impact work is large, the punching efficiency is high, and the working efficiency of the hammer is higher and more excellent.
This hammer adopts the new rock drilling theory to design the internal structure size of the hammer, so that the hammer can obtain ideal energy transmission, with large single impact power, high impact frequency, and lower air consumption; high-quality raw materials and advanced processing are selected. Process, performance is more stable, and life is longer.

Application scope of high wind pressure hammer
In actual production, it is recommended that the hammer be used in geotechnical engineering to pierce various hard rocks with poor drillability, such as medium and high hardness (depending on the type of hammer used). Currently, this type of hammer is widely used in mining, hydrology, water wells and other fields.
