ABSTRACT:
A cutting tool having improved chip runoff over a wide range of cutting conditions is provided. The cutting tool improves chip deformation and reduces cutting forces, resulting in the generation of lower temperatures and increased service life. The tool has at least two notches near a cutting corner which are positioned at an angle with respect to a cutting edge. As notches are positioned farther from the cutting corner the angle increases and the notches are spread farther apart. The arrangement reduces cutting forces even for larger feeds. In addition, the notches are provided with two opposite sides which differ in vertical slope, the side farther from the corner having the greater slope to again facilitate chip deformation and reduce friction.
