Abstract
A milling tool includes a cutting insert, a holder, a fastener and a shim. The fastener forms a first channel cooperatively with the cutting insert. The first channel is configured to direct coolant towards a top side of the insert. In order to better prevent thermal fatigue of the cutting insert under milling conditions, the shim includes a second channel configured to direct coolant towards a clearance side of the cutting insert. A method of using a milling tool and a milling process are also provided.
