Tapered button bit is a type of drilling tool work in mining, quarrying, and construction industries,which has a tapered design with tungsten carbide buttons on the surface. The raw material of these buttons are usually tungsten carbide to withstand the high impact and abrasion encountered during drilling.
(1)Button bit taper angle: 4°,6°,7°,11°,12°
(2)Models:chisel bit/cross bit/button bit
(3)Diam:20-45 mm
(4)Button bit shape:spherical/parabolic
(5)Socket inside diameter:15/19/22/25(mm)
(6)Material and process:high quality alloy steel bar and tungsten carbides, through heat treatment
1.Tapered chisel bit
Widely used in drilling holes with depth less than 5 meters and diameter ranged in 20-45 mm by light-duty rock drill, like Y6.
2.Tapered cross bit
Used under any rock drilling condition and mainly used for hard or very hard rock formation because of it's comprehensive adaptability. Compared with taper chisel bits, taper cross bits have a better drilling performance because carbide tips on cross bits doubled.
3.Tapered Button Bits
Comparing with tapered chisel bits and tapered cross bits, button bits has higher technology, much longer primary drilling time and higher drilling efficiency. According to the tungsten carbide insert, tapered button bits can be divided into the types of hemispherical, conical and parabolic button, etc.
Tapered button bit,also known as taper drill bit, is a drilling tool which has a wide applications such as mines, tunnels, and construction engineering. Its design is mainly for drilling holes in rock drilling , slope stabilization, blasting operations, usually in conjunction with handheld or mechanical rock drills.
Tapered button tooth drill bits have obvious advantages in many aspects compared to tapered chisel bits. The following are specific advantages:
1. Higher rock-breaking efficiency: The design of the button enables it to generate higher concentrated stress during the drilling process. So that it is significantly improving the rock-breaking efficiency. The distribution and shape of the button help break the rock more evenly and reduce drilling resistance.
2. Wear resistance and longer life: The raw material of the button are usually high-hardness tungsten carbide material, which has extremely high wear resistance. Therefore, it can work in high-hardness rocks for a long time, reducing the need for frequent replacement of drill bits.
3. Wider adaptability: Button drill bits are suitable for various geological conditions, including hard rock, medium hard rock and soft rock. And can adjust different taper angles and button designs according to specific needs, making it highly adaptable.
4. Faster drilling speed: Due to its efficient rock breaking ability and good stability, the drilling speed is usually faster than taper chisel drill bit.
5. Reduce overall cost: Although the initial cost is higher, the total cost of long-term use is lower due to its high wear resistance and long life. Which reduces downtime and replacement frequency and improves the overall economic benefits.
