Paying attention to these factors when buying high-quality button bits
Button bit (also called column bit) depends on the power of the rock drill and the power medium (pneumatic, hydraulic), different rocks, different powder discharge methods, and different drilling methods. There can be many buttons with the same diameter. Kind of deformation. In order to better use the button bit to make the drilling speed and tooth replacement cycle longer, the button bit is classified into tunneling drilling and production drilling (non-drilling drilling). So what elements should be paid attention to when buying button bits?
One: intensity
Knowing that the contractor uses S-grade drill rods, which have better toughness, the new steel mixture can be heat treated, and the drill rods are harder than in previous years. Other grades of steel are mainly used for other applications, such as G grade for oil and gas drilling.
Two: Value
When knowing the value of a used drill rod, an important factor is the available space. If it is placed in a traditional area, it cannot be clamped with a drill fixture. Some space may be lost due to hard strips. When buying a used drill rod At this time, we recommend to measure the pin and box tool joints, some drill rods may not have enough space to work together.
Three: quality
The quality control standards of the button bit manufacturers and the quality of the steel source are strict standards obtained from manufacturers and/or processors, and the quality of tool joints will be relatively good without bending and rotation fatigue, and no downhole failures.
The button bit has simple manufacturing process, convenient regrind, and strong adaptability to rock mass performance. It is often used with light internal combustion, electric, pneumatic and hydraulic rock drills.
