Product Description

High Efficiency DHD340 COP44 Shank Hammers High Air Pressure DTH Drill Hammer

Product Description

KINGDRILLING DTH hammer products offers a wide range of quality, versatile DTH hammers to interchangeable, or replace a number of leading industry manufacturers. Most DTH hammers are designed for use with the industry's most common rock drill bits shank types such as DHD, QL, Cop, Mission, SD, Numa and so on.

A DTH hammer is a percussion tool used in drilling operations to create boreholes in hard rock formations. Unlike traditional drilling methods where the hammer is located at the top of the drill string, the DTH hammer is placed at the bottom, directly impacting the rock with a piston-driven hammer bit. This direct impact mechanism increases drilling efficiency and accuracy, making DTH hammers the preferred choice for challenging rock formations.

How to choose the suitable Pneumatic DTH hammer?

1. 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.

1. 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.

1. 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.
