Introduction:

Round shank chisel are also called bullet teeth, bullet tooth, they belong to the necessary spare parts of rotary rock drilling bucket, core barrel and rock augers. When drilling tools do the piling job, the drilling teeth contact the rock or soil firstly, the drilling teeth cut the rock or soil, then the bored piling tools took the soil or rock out. Therefore, drilling teeth plays a great role in piling operations. How the wear-resisting degree of drill teeth and the drilling efficiency, that will directly affect the efficiency of piling progress. And, there are many different kinds of drilling teeth: B47K17.5H, B47K19H, B47K22H, C31 (kennametal teeth, betek drilling teeth)..., etc. Clients should choose the right drill bits according to the piles condition, or ask JZTG factory for professional advice.

Application:

Bullet teeth drilling tools are used with rock drilling bucket, core barrel or rock auger together for foundation bored piles piling job. The rotary piling tools with bullet teeth can be suitable for loosening water-bearing cohesive and non-cohesive soils, or breaking and ripping medium to strong weathered rock layers. hard bedrock.

Advantages:

1-Patented design, much more reasonable structure and much more durable;

2-High strength carbide tungsten drilling teeth, round holder forging center positioning quarter head;

3-JZTG carbide tip adopt low-cobalt material, bigger carbide tip, stronger abrasion resistance;

4-JZTG drilling teeth has super impact strength since the carbide tip has well-distributed micro-particles, which makes higher force intensity and reduce the risk of breaking or cracking the teeth during the bored piles piling job.

5-Bigger carbide size, smooth body surface with less resistance, multi-step of carbide teeth with low probability of partial friction, all these makes JZTG rotary drill bits has faster drilling efficiency;

6-JZTG has different types of drill teeth, suitable for different strata, JZTG could recommend the most suitable teeth according to customer requirements.

7-True factory, strong production capacity, OEM available, professional R&D team, Factory Price and Timely Delivery.
