4. How to choose the suitable Pneumatic DTH hammer?

Hole Size:

It is better for you to choose the one which the outside diameter is nearest to the hole diameter. This will reduce the hole collapse, and the hole cleaning is easier.

Air Consumption:

You must consider about the consumption of compressed air when you use the Pneumatic DTH hammer. Generally speaking, with the raising of the size of hammer, peak performance requires higher compressed gas consumption and lower pressure. In order to make sure each hammer will be used in the proper consumption of compressed air and pressure, please refer to the attachment.

Drill rig Capacity:

The larger bit and hammer will need the drilling rig to provide greater torque and promoting force, but do not exceed the maximum load of the drill. As for the other questions about drill ability, please consult your sales representative

5. Is top hammer drilling vs down-the-hole drilling?

The primary difference between the top hammer and down-the-hole drilling methods is where the hammer is attached. The hammer in the industrial equipment makes contact with the bit during the down-the-hole drilling method. The top hammer drilling method's activity is concentrated at the very top of the drill string.
