20140334887 | CLAMP TO HOLD A CUTTING INSERT ON A TOOL HOLDER - A clamp for holding a cutting insert on a tool holder and having a coolant passage therethrough to receive a coolant from a coolant supply conduit external to the tool holder and into an inlet of the clamp, and to impinge a coolant stream emerging from an outlet of the coolant passage onto a cutting interface between the cutting insert and a work piece. The flow of coolant through the coolant passage extends the life of the cutting insert by reducing heat generation at the cutting interface between the cutting edge of the cutting insert and the work piece. The coolant passage can be formed using conventional drilling tools. The clamp enables the extension of the service life of a cutting insert and can be used with conventional tool holders. | 11-13-2014 |
