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
Product specifications:
Adriller products are compatible with many products manufactured by Sandvik, Atlas Copco, etc, all our products are widely used in mining, tunneling, quarrying, construction, and civil engineering project.
DTH bits
1. manufacture as your requirement
2. bit diameter, face shape
3. carbide button shape
4. number of air hole
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.
