Abstract
The classification of different diamond bit types for drilling of jointed rock is offered. It is based on two predominant types of wear: mechanical and thermo physical. The facial and lateral on matrix body as well as cracks along the matrix body, spalling of the matrix sectors and normal wear are attributed to the mechanical type of wear. The proposed classification includes main types of wear at jointed rocks drilling and creates the grounds for the designing of rock-distributing tool more resistant to mechanical and thermo physical wear.
