Product Description

[Application scope]
This product is widely used in the exploration of mineral resources such as geology, metallurgy, mining, etc. It is suitable for drilling in medium to hard formations (f = 7 ~ 15), and is not suitable for use in broken and fissured formations.

[Technical features]
Surface set bits have excellent adaptability in a wide range of formations. The bits provide high drilling efficiency even in very demanding drilling conditions. Optimal drilling performance can be obtained by selecting bits with corresponding profiles, such as the crown shape and the matrix formula, to match the rock formation.

Impregnated bits have excellent adaptability in a wide range of formations. The bits provide long service life and high drilling efficiency in a variety of drilling conditions and they are simple to operate. Optimal drilling performance of bits can be obtained by adjusting the diamond size and concentration, the hardness of the matrix and the crown shape.
