Drilling rock-breaking tool
Diamond impregnated crowns for single core drilling
Impregnated diamond crowns are designed for drilling in a wide range of hard and very hard rocks of the VII – XII categories of drillability: from monolithic to fractured and fragmented, from low-abrasive to very abrasive, of various granularity and density.

Matrices
For the manufacture of diamond impregnated drill bits, 6 matrices are used, which differ in wear resistance (hardness). They are indicated by numbers from 1 to 6.
With an increase in the number of the matrix, its wear resistance (hardness) increases.
Matrix No. 1 is the softest and is designed for drilling on extremely hard, non-abrasive, very fine-grained and monolithic rocks.
