Tool for the machining of a workpiece with lateral coolant outlet

摘要

A tool for machining a workpiece is presented. The tool has a cutting insert with at least one cutting edge, a holder having a shank, and a cutting insert receptacle, wherein the cutting insert receptacle is arranged in a region of a workpiece-side end face of the shank, and the cutting insert is disposed in the cutting insert receptacle. The holder has a coolant bore, which opens out into a plurality of coolant outlets. The plurality of coolant outlets are arranged on the workpiece-side end face of the shank, alongside the cutting insert receptacle, and are oriented such that coolant is discharged towards the cutting insert. At least some of the coolant outlets lie in a coolant outlet plane which runs parallel to and offset from a cutting insert plane running through the cutting insert receptacle, where the coolant outlet plane and the cutting insert plane run parallel to the longitudinal direction of the shank.
