Specifications
1.High hardness, wear resistance.2.Quality is in the leading position in the same industry.
3.Long work life.
4.ISO9001
A. Steel material.
We only use quality 42CrMo as steel body. This kind of steel of ultra high strength steel,
intercritical quenching conditions can be obtained in martensite and a small amount of uniformly
distributed fine ferrite, this organization under the premise of ensuring the strength of improved
toughness. Has high wear resistance, high fatigue limit, strong toughness, which is to ensure the
quality of cutting teeth of the basic factors.

B.Heat treatment Technology
In the light of bit alloy heads around the portion of generally wear,
we developed the super abrasive cutting tooth, in this area have been adopted for ultra
deep w alloying process, while the hardness is not greatly increased, but the infiltration
of component greatly enhanced wear resistance, but still maintain toughness, and using
high quality imported hard alloy head. After many trial effect of mine, has reached or even
exceeded imports pick.
The coal bits are mainly used in coal and mine drilling.
We can manufacture all kinds of bits and shells according to customer's special requirement.
Any requirement please contact us, we'll do the best service for you. Hope we can establish a good business relationship.
