CIR70 CIR90 CIR110 Low Air Pressure DTH Drilling Button Bits

CIR series DTH hammer, a kind of valve-equipped Low Air Pressure hammer with single piston, a plate valve and a central exhaust structure. The compressed air is adopted as the driving force. To prevent dust pollution and get a better performance, some high-pressure water may be added into the air for wet rock drilling.

Code No.: CIR90-90

Diameter: 90mm

Gauge Buttons: 6

Front Buttons: 4

Carbide Design: Ballistic

Face Design: Convex

Shank Type: CIR

It is mainly featured in:

1. The strong energy of single impact and the low engergy consumption in rock crushing.

2. The weight ratio of piston and bit almost reaches 1:1 to provide long effective acting time, which leads to the improved efficiency in rock crushing and the extended service life of the drilling tool.

3. A good performance in central air exhaust and cutting discharge, which reduces the repeated crushing of rock.

4. A check valve device is available to drill holes under water.

The CIR series DTH hammer, an ideal drilling tool, is widely used in such industries relating to energy,transportation,metallurgy,building, etc...
