Description:

Brief introduction of our low air pressure DTH hammer:

The CIR series DTH hammer is a low-pressure hammer with a valve, with a single piston, a plate valve and a central exhaust structure. Use compressed air as the driving force. In order to prevent dust pollution and obtain better performance, some high-pressure water can be added to the air for wet rock drilling.

Its main features are:

1. Strong impact, low energy consumption of crushed stone;
2. The weight ratio of the piston to the drill bit is close to 1:1, which provides a longer effective action time, thereby improving the efficiency of rock breaking and prolonging the service life of the drill;
3. Central air exhaust, good chip removal performance, reducing repeated rock fragmentation;
4. You can use the check valve device to drill holes in the water extractor.
CIR series down-the-hole hammer is an ideal drilling tool, widely used in energy, transportation, metallurgy, construction and other related industries.
