PRODUCTS DETAILS

Rotary digging pick is a kind of construction machinery for hole forming operation in building foundation engineering. It is mainly suitable for the construction of sandy soil, cohesive soil, silty soil and other soil layers. It is widely used in the construction of cast-in-place piles, continuous walls, foundation reinforcement and other foundation foundations The picks of rotary drilling rig are referred to as rotary drilling picks and rotary drilling picks. The picks used for rotary drilling rigs are: BZ47-22, BZ47-19, BZ47-17, 3050-19, 3050-22, 3060, C21, C23, C31, C34, C35, RZ47, 3050, RZ223059, RZ29, RZ31, RZ40, RZ60, RZ65, RZ70, RZ72, RZ80, etc

Advantage: 1. The carbide tip use the low-cobalt material, with bigger carbide tip, with stronger abrasion resistance. 2. Advanced processing, to guarantee the carbide tips high quality. 3. The carbide tip has well-distributed micro-particles, with super impact strength, it will make higher force intensity during the drilling, and reduce the risk of breaking or cracking the teeth. 4. The body material is 42CrMo, high wear-resistant, strong toughness, strong compression and impact resistance, extend the using life. 5. The carbide tips of new design (unique mesh style outlook) have tower shape or step shape, which makes the bullet bits scatter out the rock pieces more smoothly, the efficiency can reduce 20%; comparing the traditional bullet bit, the drilling efficiency of the new one can increase 33%. It can better service for drilling weak weathering rock 60-70Mpa, hard rock 80-90Mpa, except 100Mpa. 6. Streamlined body design of new design teeth (unique mesh style outlook ) make the teeth have better rotation, less resistance. Note: Teeth with multi-step tungsten carbide could increase the cutting capacity and extend cutting life.
