The concept of invention: a tool for crushing hard material comprises a housing and a hard-alloy insert mounted on the latter. The insert is made up of a head portion, an intermediate portion and a base with a thrust face. The intermediate portion of the insert is formed by a body of revolution with an outer lateral surface of concave shape. The head portion of the insert is formed by a body of revolution with an outer lateral surface of convex shape. The lateral side of the head portion of the insert is smoothly located adjacent to the lateral side of the intermediate portion of the insert. The length of the intermediate portion of the insert about its longitudinal axis does not exceed the length of the head portion of the insert about the same axis.
A tool for crushing hard material, comprising a housing and a hard-alloy insert mounted on the housing and having a head portion, a base with a thrust face for interaction with a supporting surface of the housing and an intermediate portion interposed between the head portion and the base and formed by a body of revolution with an outer lateral surface of concave shape, characterized in that the head portion of the insert is formed by a body of revolution with an outer lateral surface of convex shape, and the lateral side of said head portion of the insert is smoothly located adjacent to the lateral surface of its intermediate portion, the length of the intermediate portion of the insert about its longitudinal axis not exceeding the length of the head portion of the insert about the same axis.
