How to choose the Thread Button Bit tooth type:
Spherical buttons: The height of exposed teeth is low, mainly used in the very hard rock formation above F14. Lower drilling speeds should be used to optimize wear resistance and reduce debris buildup.
Ballistic buttons: They may expose more button height and are typically utilized in soft rock and common rock below F12. However, when they face hard rock, buttons debris phenomena are highly likely to occur.
1. Thread Button Bit for soft rock
Uses: primarily used in non-crushing hardness, hardness F=8 or less, non-abrasive rock, it's more suitable to take new drop center face, the Thread Button Bit diameter is small, with ballistic or semi-ballistic buttons, which will make it easier to discharge debris to help improve work efficiency, and the tungsten carbide wear resistance is good.
2. Medium-hard rock Thread Button Bit
Uses: Used in non-abrasive, common rock with a hardness of F=8~14. It is better to use a flat face, a Thread Button Bit diameter, and spherical buttons.
3. Hard rock Thread Button Bit
Uses: Tungsten carbide buttons are more impact and wear-resistant than standard types, but they cost more due to their larger button diameter. They are mostly employed in rocks with a hardness above F=14 that are not abrasive.
4. Abrasive rock Thread Button Bit
Uses: Utilized primarily in high-abrasive quartz rock, the button's diameter and height are large, its face is smoother than average to make it easier to remove rock slag, and it has improved impact and abrasion resistance.
5. Retractable Thread Button Bit
Uses: It is primarily used in rocks with gaps and rocks with variable rock formations. It takes drop center face with retract design, and the Thread Drill Rods and bits can be taken apart more quickly.
