    Abstract: A turning tool holder with a turning tool holder shank and a turning tool holder head is described. In an installed position of the turning tool holder, a longitudinal extension direction of the turning tool holder head is a longitudinal extension direction of the turning tool holder shank which continues straight-ahead, at an angle, or over a radius. The turning tool holder head, seen in its longitudinal extension direction, thereby has two side faces, wherein a lateral coolant outlet is provided on one of the side faces, the lateral coolant outlet center axis of which lateral coolant outlet, in plan view, is predominantly oriented along the longitudinal extension direction of the turning tool holder head. In addition, a turning tool with such a turning tool holder is presented.

    Abstract: A cutting insert includes a tool carrier having a body with a pocket, and a cutting tip affixed to the pocket by brazing. The pocket is defined by a vertical back wall and a horizontal support surface. A notch is formed at the intersection between the vertical back wall and the horizontal support surface. The notch has a non-planar first portion proximate the vertical back wall and formed with a radius, R1, and a planar second portion extending between the first portion and the horizontal support surface and formed at an inclination angle with respect to a plane parallel to the horizontal support surface of the pocket. The design of the notch significantly reduces thermal stress and eliminates the formation of cracks in the pocket of the tool carrier when using an injection molding process to form the tool carrier.

    Abstract: A turning toolholder includes a shank, a club head, and a clamp and a clamp screw for clamping a cutting insert. The club head includes a clamp coolant supply hole in fluid communication, a flank coolant supply hole and an auxiliary rake coolant supply hole, all in fluid communication with the main coolant supply hole. Coolant is supplied through a rake coolant exit opening formed in the forward nose portion of the clamp to direct coolant to the top rake surface of the cutting insert, and coolant is supplied through a flank coolant exit opening located below the insert-receiving pocket to provide coolant to the side flank surfaces of the cutting insert. In addition, an auxiliary rake coolant supply housing formed on a top surface of the club head supplies additional coolant to the top rake surface of the cutting insert during high heat applications.
