Mining Carbide Drilling Tools DTH Hammer Drill Bits For Water Well
Drill Rigs
Production Description:
DTH bit is the tool cutting rock. DTH bits are made of superior
quality alloy steel which is made by Timken in U.S. Besides, all
our DTH bits are using the brand "Element Six" T.C carbide, which
provides (the T.C buttons) for Boart Longyear. In addition, art
manufacturing technology makes our DTH bits with higher and more
reliable quality.
Advantage:
1. Valveless air distribution, more reliable.
2. Piston with simple but compact design, long life.
3. More efficient energy transfer, faster-drilling speed, lower air
consumption, and lower oil consumption.
4. Fewer internal parts, simple structure, longer life, less
failure, and easier to maintain, with all heat-treated parts;
5. Easy to disassemble, thanks for the top sub, drive chuck and
external cylinder all are connected by a multi-step thread.
Application:
1. Suitable for high-pressure drilling rigs
2. Water well drilling
3. Record-breaking penetration
4. Exploring Civil Engineering Applications
5. Lowest cost per foot drilled
6. Simple & robust design
7. Exploring Civil Engineering Applications
8. Foot Valve not required in the bit
9. Longer parts of life
10. Maximizes efficiency

How to Select Threaded Button Bits Face shape and Carbide Button
Shape
Drop Center
For high penetration rates in soft to medium-hard and fissured rock
formations.
Concave Face
The all-round application bit face is specifically for a
medium-hard and homogeneous rock formation. Good hole deviation
control and good flushing capacity.
Convex Face
For high penetration rates in soft to medium-hard with low to
medium air pressure. It is the most resistant to steel wash, and
good resistance to steel wash step gauge bit.
Flat Face
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.
B: Insert Carbide Button shape Selection
The different button is ideal for different ground conditions,
abrasive levels, and penetration levels. In general, the more gauge
buttons, the better over performance, especially in hard rock.
Features of our Threaded Button Bits:
* Be produced from premium quality Nickel-alloy steel or
Molybdenum-ally steel for increased durability and wear
characteristics
* Specific heat treatment standards and strict production process
ensure consistent performance
