Abstract
A cutting tool for metal cutting with a cutter having parallel base surfaces and grooves machined into the side surfaces, forming cutting edges, which can be inserted into the recesses of a tool holder. The cutting tool has a center bore for accommodating a clamping element and is made from a parallelepiped-shaped base body with rectangular and preferably square sides wherein the base edges of grooves successively run in the direction of a diagonal of the side surfaces of a parallelepiped similar to the parallelepiped-like base body inscribed so that the base surfaces of the cutter are rhombic.
Claims12
A cutting tool arrangement for metal cutting comprising, in combination, a base body having parallel base surfaces and grooves machined into the side surfaces for forming cutting edges, said cutting tool being insertable into recesses of a tool holder and having a center bore;
- said base body having rhombic-shaped cross-sections parallel to said base surfaces and having V-shaped sides formed by relief surfaces intersecting in a line between said parallel base surfaces, said parallel base surfaces of said base body being rhombic-shaped with vertices, said line extending along one side of said base body, said line extending from one vertex of one parallel base surface to a predetermined vertex on the opposite parallel base surface, said predetermined vertex lying diagonally opposite said one vertex, said predetermined vertex lying also opposite a vertex on said one base surface adjacent to said one vertex, said line extending along one side intersecting at both ends with lines on adjacent sides, said lines being interconnected in sequence and forming a rhombus in a plane inclined to the planes of said parallel base surfaces, said lines forming base edges of said grooves.
