Product description
High Pressure DTH Air Drill DHD3.5 is very popular in international mining drilling and rock excavation field.
Product introduction:
Down-the-hole rock tools (drilling tools) are rock drilling equipment which takes compressed air as power source to partially transfer impact power into drilling holes. An air distributing device in a top hammer controls a piston to move back and forth. An impact device arranged in the front of the top hammer transfers the impact powder to a down-the-hole bit to crush rocks.

Product features
1.The simple structure of the hammer makes the consumable parts extremely few and easy to disassemble and assemble.
2.The mechanical design produce a powerful blow energy to hit the bit, making it capable to perform in low and high pressure.
3.Precision machining using high quality materials ensures little breakdown and stable performance for a long time.
Application
The principal drilling methods used in mines today are mechanical ones in which a drill drives cutting tools into rock by means of static or dynamic force. Percussion rock drills are the most commonly used equipment for drilling in small-scale surface or underground mining situations, whereas rotary crushing drills or down the hole drills (DTHs) are generally employed for mining in large-scale surface mines.
Sollroc , with more 10 years of experience ,is one of the professional manufacturer and supplier of high performance rock drilling tools like: DTH hammers and bits, RC hammers and bits, DTH drill rods and top hammer drilling tools. Our tools are widely used in different drilling applications including mining, quarrying, water well drilling, geotechnical industries and etc.
