Product Description
Product Introduction
DTH drilling is very simple method for the operators for deep and straight hole drilling. In the hole range 100-254 mm (4" ~ 10"), DTH drilling is the dominant drilling method today (especially when the hole depth is greater than 20 meters).
Company Introduction
1. Our factory has been specialized in manufacturing drilling tools and spare parts for over 10 years.
2. We have advanced technology and equipment.
3. Our technician has more than 13 year's professional working experience.
Product Features
1.Wide range of holes sizes, including extremely larger hole diameter.
2.Excellent hole straightness within 1.5% deviation without guiding equipment, more accurate than top-hammer, due to the impact being in the hole.
3.Good hole cleaning, with plenty of air for the hole cleaning from the hammer.
4.Good hole quality, with smooth and even hole walls for easy charging of explosives.
