Since its invention in the early 1840s, the down-the-hole (DTH) hammers have been a boon in the field of boring and drilling. The DTH technique was created to drill big holes vertically in ground drilling and other industrial applications. The rapid hammering process shreds hard rock into small fragments and dust. They are then blown away by a fluid, be it air, water, or the drilling mud itself.
But to excel in the project you undertake, you need to choose the correct DTH hammer. This brief guide is just to help you out and make you understand how to choose the one that’ll fit your purpose at the best DTH hammer price.
Selecting the Best DTH Hammer
You should keep the following points in mind while choosing the right DTH hammer for your projects:
Size
The diameter of the hole and the nature of rocks have a big role in choosing the right hammer size. 3.5 to 10 inches is the best range of blast holes for DTH drilling. Smaller holes are typically drilled with a top hammer rather than a DTH hammer, and larger holes generally use the rotary drilling technique, mainly with the focus on hole straightness.
Pipes
In comparison to tubes manufactured from hot-rolled tubing, pipes or tubes made from cold-drawn tubing have a better surface polish, precision, and consistency. A superior polish decreases the possibility of scaling, which is caused by metal chips from the ducts. A primary cause of untimely hammer breakdown is scaling that runs through the hammer.
Joints
Friction-welded joints add to the overall strength of the structure. Heat treating end-piece threads guarantee the thread profile's maximum endurance and strength. Maintaining the thread profile allows for seamless coupling and uncoupling without adding time to the average penetration rate.
