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.

First claim

The invention claimed is:

1. A turning tool holder, comprising:
a turning tool holder shank having a longitudinal extension direction; and
a turning tool holder head having a mounting pocket configured for mounting a cutting insert therein, the turning tool holder head having a longitudinal extension direction, the turning tool holder head including a top face, an underside face opposite the top face, two opposing side faces connecting the top face and the underside face, and a front face opposite the turning tool holder shank,
wherein the front face includes a frontally projecting extension having a frontal coolant outlet, the frontal coolant outlet having a frontal coolant outlet center axis oriented in a direction that is substantially transverse to the longitudinal extension direction of the turning tool holder head and directed toward the mounting pocket for the cutting insert,
wherein the top face includes at least one coolant outlet having a coolant outlet center axis oriented in a direction that is substantially transverse to the longitudinal extension direction of the turning tool holder head and directed toward the mounting pocket for the cutting insert,
wherein one of the two opposing side faces includes a laterally projecting extension having at least one coolant outlet with a coolant outlet center axis oriented in a direction that is substantially parallel to the longitudinal extension direction of the turning tool holder head and directed toward the mounting pocket for the cutting insert.

2. The turning tool holder of claim 1 , wherein the front face of the frontally projecting extension is facing toward the mounting pocket for the cutting insert.

3. The turning tool holder of claim 1 , wherein the frontal coolant outlet center axis is substantially transverse to the lateral coolant outlet center axis.

4. The turning tool holder of claim 1 , wherein the frontal coolant outlet center axis is inclined at an upward angle of between about 15 degrees to about 60 degrees with respect to the longitudinal extension direction of the turning tool holder head.

5. The turning tool holder of claim 1 , wherein the frontal coolant outlet center axis is inclined at an upward angle of between about 35 to about 50 degrees with respect to the longitudinal extension direction of the turning tool holder head.

6. The turning tool holder of claim 1 , wherein the front face is formed at an oblique angle with respect to the top face of the turning tool holder head.

7. The turning tool holder of claim 1 , wherein the coolant outlet center axis is substantially transverse to the lateral coolant outlet center axis of the at least one lateral coolant outlet.

8. The turning tool holder of claim 1 , wherein the longitudinal extension direction of the turning tool holder shank and the longitudinal extension direction of the turning tool holder shank are aligned at an angle of 180 degrees with respect to each other.

9. The turning tool holder of claim 1 , wherein the longitudinal extension direction of the turning tool holder shank and the longitudinal extension direction of the turning tool holder shank are aligned at an angle of 90 degrees with respect to each other.

10. The turning tool holder of claim 1 , wherein the lateral coolant outlet center axis is inclined at an angle greater than 0 degrees and less than or equal to about 80 degrees with respect to the longitudinal extension direction of the turning tool holder head.
