Cutting tool and shank

摘要: A cutting tool particularly adapted for machining brittle plastics in which the head has its edges first and fourth quadrants of x-y axes contained a common plane on opposite sides axis rotation. The are two planar inserts, can be either integral or separate elements, meet at each is relieved cut away quadrant from own edge to expose other. walls defining reliefs have 2 more non-aligned sections forming different angles with rotation steepest angle beginning preferably inwardly tip and, overall, exposing not less than full other insert while providing cavities contours control movement chips flow coolant fluids. shank holds includes fork whose tines embrace inserts include contouring compatible geometry allow flows coolant, paths formed complementary fashion.
