MODULAR CUTTING TOOL Russian patent published in 2012 - IPC B23B27/16 B23B51/00 B23C5/22 B23D77/02 

FIELD: process engineering.

SUBSTANCE: proposed tool comprises body with at least one recess limited by lower wall and sidewall or lateral walls, at least one cutting plate arranged in said recess radially or tangentially and secured by fasteners to have lower and lateral thrust surfaces, or lateral thrust surfaces to interact with recess lateral walls. Note here that mounted cutting plate has working angle or working section of cutting edge. To add to durability, recess lower and lateral walls or lateral walls are provided with contact sections made up of annular ledges produced by tapered, or pyramidal or spherical indenter penetrated into said walls. Note here that in the case of cutting plate radial arrangement in said recess, three or more contact sections are arranged on recess lower wall, while in tangential arrangement there are two or more contact sections. Note also that one of said contact section is arranged at working angle of cutting plate or working angle of its cutting edge.

EFFECT: higher durability and ease of use.
