DTH Bits manufacturers

What is the function of DTH bit?
A DTH bit (down-the-hole bit) is a drill bit used to drill holes in rock or other hard materials. The function of a DTH bit is to break and displace rock or other material by applying high frequency, high impact forces to the bit. This makes it easier for the drill to penetrate the material and create the desired hole size and shape. DTH bits are commonly used in mining, construction, and oil and gas drilling operations.

What are the types of drifter bits?
A drifter bit is a tool that rotates and has cutting capability at the tip. It is made of carbon steel SK or high-speed steel SKH2, SKH3 and other materials, which are milled or rolled and then quenched and heat-treated. Mainly used for drilling on metal or other materials. It has a wide range of applications and can be used on machine tools such as drilling machines, lathes, milling machines, and electric drills. The drifter bit can be divided into the following types according to different types:
1. Classification by structure: There are integral drifter bit and end-welded drifter bit. Integral drifter bit means that the drill top, drill body, and drill shank are integrally made of the same material; while the end-welded drifter bit has the drill top part welded by carbide.
2. Classification by drill bit: There are straight shank drifter bit and tapered shank drifter bit. Straight handles are used for drifter bit diameters below φ13.0mm. Taper shank drifter bit is that the shank of the drifter bit is tapered, and generally its taper adopts Morse taper.
3. Classification by application: center drifter bit, twist drifter bit, superhard drifter bit, oil hole drifter bit, deep hole drifter bit, drifter bit reamer, taper drifter bit, conical hole drifter bit, cylindrical hole drifter bit, etc.
The above is the introduction of the types of drifter bit, you can understand it.

What are the characteristics of the commonly used rock button bit?
The cemented carbide drill bit breaks the rock by the impact load generated by the drilling pressure and its own rotation. In rock drilling, the drill bit is subjected to high-frequency impact loads, and is subjected to multiple compound stresses such as torsion, bending, tension, and compression, and is subjected to rock, rock powder, and mineral water in a high-speed rotary collision environment. Media wear and corrosion.
Most of the roller cone bits used at home and abroad are tri-cone bits. The characteristics of this kind of drill bit are: the distribution range of axial pressure and impact load is large and uniform, and the effective space can be fully utilized, and the drilling is stable. The size and shape of the cemented carbide teeth for the roller cone bit must be suitable for the characteristics of the rock, requiring good wear resistance, high strength, and not easy to break and break. The cemented carbide teeth used in the roller cone bit mainly include: spherical teeth, conical spherical teeth, wedge teeth, side wedge teeth and flat-top teeth for the back of the wheel and the tip of the claw.
Generally, the roller cone bits for drilling into extremely hard rock formations mainly use spherical teeth, the drilling pressure is 892~1339MPa, and the speed is 50~80r/min; the roller cone bits for drilling hard and medium hard rock formations use conical spherical teeth. The pressure is 714~1071MPa, and the speed is 60~100r/min; the roller cone bit for drilling soft and medium soft rock formations uses wedge teeth or side wedge teeth, the drilling pressure is 535~803MPa, and the speed is 80~120r/min.
