3 Inch DTH Hammer

A 3 Inch DTH Hammer refers to a Down-The-Hole (DTH) hammer with a drilling diameter of approximately 3 inches. DTH hammers are essential tools used in various drilling applications, especially in mining, quarrying, construction, and water well drilling.

Here's how 3 Inch DTH Hammer works:

Principle: 3 Inch DTH Hammer works on the principle of percussive drilling. Compressed air or other suitable drilling fluids are used to create a high-velocity, high-frequency hammering action at the bottom of the drill string.

Piston and Impact Bit: Inside the 3 Inch DTH Hammer, there is a piston that moves up and down under the influence of compressed air. This motion impacts the back of the drill bit, transmitting a powerful force to the drill bit's face.

Drilling Process: The hammering action combined with the rotational force (if the drill string is rotating) breaks the rock or other materials at the drill bit's face, creating a borehole.

Removing Cuttings: The high-pressure air or drilling fluid also helps to flush out the cuttings from the hole to the surface.

The diameter of the DTH hammer is an essential factor as it determines the size of the borehole. A 3 Inch DTH Hammer would be suitable for drilling holes with a diameter of approximately 3 inches or slightly larger, depending on the specific model and design.
