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.
