Product Description

N120 N125 SD12 Shank High Air Pressure DTH Hammers for Well Drilling

Product Description

The core components of a DTH hammer include a piston, bit, chuck, and drill pipe. When pressurized air is forced down the drill pipe, it activates the piston inside the hammer, which strikes the bit at the bottom. The bit then fractures the rock, creating the borehole. The exhaust air and debris are flushed up the drill pipe, clearing the hole for further drilling. This continuous cycle of impact and flushing ensures rapid progress in drilling operations.

Advantages of DTH Hammers:

1. Efficiency: DTH hammers are known for their high drilling rate, allowing for faster completion of boreholes compared to traditional drilling methods.
2. Precision: The direct impact mechanism of DTH hammers results in precise borehole alignment and depth control, crucial for applications like mining and geothermal drilling.
3. Versatility: DTH hammers can be used in various rock formations, including hard and abrasive rocks, making them versatile tools across different industries.
4. Cost-Effectiveness: The speed and accuracy of DTH hammers reduce drilling time and operational costs, making them a cost-effective choice for large-scale projects.

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

 

Product Application
