Down the hole(DTH) hammers and drill bits for drilling
Because of economy and powerful drilling capacity, down the hole hammer become an advanced drilling tool for drilling and mining industries. Down the hole hammers and drill bits are designed together to work in perfect unison, giving high penetration rates, long service life and low costs.
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 multihead thread connecting chuck and cylinder of hammer.
5. Interchangeable with DTH bit and drill pipe
Low pressure and high pressure hammers are available in our company.
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-around application bit face specifically for medium hard and homogeneous 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 theload and wear on the gauge buttons, but poor hole deviation control.
4. 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.
Carbide Button Shape Selection:
1. Semi-Ballistic Buttons
2. Ballistic Button
3. Spherical Button
4. Two-step Button
