High-Performance DTH Hammer Drill Bits for Hole Drilling

Product Description

Advantages:High-Performance DTH Hammer Drill Bits for Hole Drilling

Product Description

1.Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to inner structure of DTH hammer designed according to newest rock dilling theory.

2.Smooth performance and long service life of DTH hammer due to high quality alloy steel materials and advanced processing technology adapted.
 
3.Low problem rate and easy to maintenance due to simple , reliable and easy assemble and disassemble inner structure of hammer.
 
4.Easy to depart bit from hammer due to multi-head thread connecting chuck and cylinder of hammer.
 
5.Interchangeable with DTH bit and dill pipe manufactured by many brands all over the world.

Our Advantages

1. Using the latest rock drilling theory, optimizing the inside structure and the size of the air distribution, to make the DTH Hammer obtain the optimal energy transfer and make it achieve faster drilling speed and lower air consumption.

2. For such projects as the drill bit break, retrieving very difficult, we specially designed a safe and reliable anti-shedding device for the bit.

3. The check valve can be replaced to the one with bigger ail controlling hole to provide more efficient cuttings discharge.

4. The top sub and the drive chuck have special thread, which can achieve an easier disassemble.
