tricone bits are designed for the most severe rotary blasthole applications, yet are cost effective for a wide range of drilling needs. The new bit line includes six diameters ranging from 200 mm (7 7/8 in.) to 311 mm (12 1/4 in.).



Mining Blasthole Drilling Rotary Tricone BitMining roatry tricone drill bit always used for the drilling of the production hole in open pit mining.



1. It has the characteristics of long life, high reliability, fast penetration rate and strong track keeping ability. 

2. The ideal choice for drilling and drilling in hard formations and strong abrasive formations.

3. The size range is 7 7/8-12 1 / 4 inches.

4. Long life and high reliability.




To increase efficiency and lower drilling costs, blasthole rigs are expected to deliver more and more energy to the drill bit. As a result, drill bits must be carefully designed and manufactured to not compromise the productivity and efficiency of increasingly complex and expensive drilling systems. Bits have become an even more critical and vital component in this process.


We supply a range of highly energy-efficient and productive point-attack cutting tools, suitable for both civil and mining applications. Combining tool design, high-grade alloy steel and premium grades ensure that we meet your performance demands.




Wuhan Yijue Tengda Machinery Co., Ltd. is a professional manufacturer engaged in the design and production of foundation rotary drilling tools and mining tricone bits. Our main products include: drilling buckets & augers, core barrel,drill bits,casings,tremie pipes,single roller cone bits and mining blasthole tricone bits.

We started to engage in the production and sales of mining blasthole tricone bits because we have accumulated rich experience in the production of single roller cone bits.

We are delicated to serve for the foundation drilling/piling  and blasthole mining industry.
