Detail Introduction
Down-the-hole drill bit
1. Transverse convex type: this bit is divided into two forms, single and double face convex convex, which is mainly used for large diameter DTH bit face convex type DTH drill bits in drilling hard and hard abrasive rock can keep high drilling speed, but bore straightness is bad, do not apply to the hole straightness to demand higher drilling engineering
2. Transverse plane type: the shape of the drill more strong and durable, suitable for drilling hard and very hard rock, but also drill hole straightness of request is not high in hard rock and soft rock
3. Transverse plane type: the shape of the drill bit end portion of a conical depression, is a bit in the process of drilling bit form mild nucleation effect to the performance, the drill hole have good straightness, this bit row powder effect is good, drilling rate is fast, is currently on the market use more DTH drill
4. Face deep concave center type: the shape of the bit is made up of the same type evolved the ball tooth drill head, drill the end face of a deep concave center to the center part used for the nucleation effect in the process of drilling, when drilling deep hole to ensure that the hole straightness, only applicable to drill in soft rock and hard rock
