Abstract
A tool holder includes an insert having an annular channel in fluid communication with an inlet. The insert mounts within a body that provides for rigidly mounting the tool to the machine. Coolant flow through the inlet and annular channel exits the insert through passages directing coolant fluid along the axis of the tool. The passages are annularly disposed about a face of the insert for directing coolant fluid along the tool.
Claims12
An endmill tool holder assembly comprising;
- an inlet for cooling fluid;
- a body portion including a bore sized to receive an endmill tool along an axis, said body portion defining sides of an annular channel in fluid communication with said inlet, the bore receiving the tool extends through the body portion and in communication with the inlet for cooling fluid, the body further including a mount portion comprising a circumferential groove and a tapered body portion extending rearward from the mount portion that provides a mating surface for mounting within a machine;
- at least one cross-channel in communication with the bore;
- at least one axial channel in communication with the bore on a first end and the annular channel on a second end for communicating cooling fluid around the tool within the bore and to the annular channel;
- and
- an insert fit into said annular channel including coolant openings disposed at an angle relative to said axis.

An endmill tool holder assembly comprising;
- a body portion including a notch extending circumferentially about the body portion and a tapered portion that narrows in a direction rearward from the notch;
- a bore extending through the body portion from an inlet for cooling fluid on a first end to an opening sized to receive an endmill;
- at least one cross-channel transverse to the bore and in fluid communication with the bore;
- a least one axial channel disposed parallel to the bore and extending from the at least one cross-channel to an annular channel;
- an annular channel disposed circumferentially about the opening for the endmill;
- and
- an insert pressed into the annular channel, the insert including a plurality of openings for directing cooling fluid onto a portion of an endmill extending outward from the bore.
