тот вид износа случается, когда зубья шарошек, подобно шестерне, образуют забойную рейку.

В этом случае имеет место износ набегающих или сбегающих гране зубьев, также происходит износ тела шарошки между зубьями, о некоторых случаях можно избежать рейкообразования, применяя долота та для бурения более мягких пород и (или) снижая по возможности гидростатическое давление на забой.
