Adriller Drill Bit
Adiller line of top hammer bits, also commonly referred to as button bits, have been specially designed to drill through almost any type of hard and abrasive rock formations.
These drill bits not only have a superior penetration rate compared to their competitors, but also a substantially longer service life – up to 30% longer
Description:
After Annealing, The Hardness Is Not More Than Hb260,
Make The Rock Drill Bit Easy To Cut Rock ; Heat Treatment Process Is Simple, Easy To Control, Air Cooling Hardness Should Reach Hrc40 ~ 45, Oil Cooling Hardness Can Reach Hrc48 ~ 55; Good Solderability
The Interface Between The Solder And The Steel Body Can Form a Solid Solution Alloy
The Coefficient Of Linear Expansion Is Close To That Of The Hard Carbide Button To Reduce The Welding Stress; The Steel For The Carbide Button Bit With Hot-Inserted Teeth Should Have a High Coefficient Of Linear Expansion In The Temperature Range Of The Carbide Button . And Still Maintain a High Hardness, Strength And Toughness.
Applications:
Mining, quarry, road building, well hole drilling, blasting, landslide prevention, dam reinforement, anchoring, geothermal, hydrology, etc.
Feature Advantage:
1. Non-Blocking:Our S-series DTH hammers are proved to ensure extremely low rate of blocking during it works.
2. High Efficiency:The well drilling equipment carries with larger power of impact frequency and torque, thus ensuring faster penetration. Compared with others, the efficiency can be improved 10%.
3. Longer Service Life:All surfaces of the DTH hammer and bits are treated by anti-friction and intensified technology. When used in deep-hole drilling works, it can reach at 5000 meters or more.
4. Excellent Cleaning Effect: This DTH tool has large air output, which specially designed for water well users and enables it to flush out cuttings in deep hole drilling
