Abstract: A cutting insert for cutting, milling or drilling of metal includes a body having an elongate recess extending along at least a portion of the body, a first layer covering interior side walls of the recess, and a sensor arrangement. The body includes a substrate. The sensor arrangement includes sa lead extending along the recess. The lead includes electrically conductive material, which is arranged in the recess such that the first layer is located between the electrically conductive material and the substrate. For at least a depth below which at least a portion of the electrically conductive material is arranged in the recess, a width of the recess measured at that depth between portions of the first layer covering opposite interior side walls of the recess is less than or equal to 80 micrometers.

Abstract: A coated cutting tool includes a substrate with a rake side, a clearance side and a cutting edge, and a coating including a first layer and a second layer. The second layer includes an inner layer and an outer layer, wherein the first layer is exposed through an opening in the inner layer and the opening extends over at least a portion of the width of the cutting edge. Thereby, a double layer is provided in critical areas, whereas a single layer is provided in other areas. Preferably, the double oxide layer includes aluminum oxide layers. A method for manufacturing the coated cutting tool is also provided.
