 Mining carbides taper button rock DTH drill button bit
 
Brief introduction of our DTH hammer:

Bit face shape selection:
1. Drop Center Bit
For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.
2. Concave Face
The all-round application bit face specifically for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.
3. Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.
4. Double Gauge Face
This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.
5. Flat Face Bit
This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.

How to Chose the Right Products :
Choosing the right hammer is determined by drill machines (mainly compressor output), drilling hole size and type of rock formation. Ideally, the size of the hammer should match the required hole dimension as closely as possible, leaving just enough space for compressed air to flush cuttings and clean the hole.
 
The optimum range of hole size for blast-hole drilling with DTH method is 90~254 mm (3-1/2"~ 10") with 3.5 ~ 8" hammers. Smaller blast holes are generally drilled with top-hammer tools, while larger holes typically with rotary drilling tools. In other applications, like foundation drilling, DTH hammers can be used in hole size up to 1,000 mm (39-3/8").
 
Usually, the smallest hole diameter a DTH hammer can drill is its nominal size, for example, a 4"hammer would drill a 4" (100/102 mm) hole. The limiting factor is the outside diameter of the hammer, because, as hole diameter reduces, airflow is restricted. Maximum hole size for production drilling is the nominal hammer size plus 1"for 5" and smaller hammers and plus 2 for 6" and bigger hammers, for example, for a 4" hammer the maximum hole size is 5" (127/130mm) while for a 8"hammer the maximum hole size is 10" (254mm).  
 

Advantages:

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

2. Smooth performance and long service life of HD series 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 drill pipe.
