    Abstract: A method for non-destructive testing a cutting insert to determine coating thickness is disclosed. The method includes the steps of using a source of electromagnetic energy to ablate a surface of the cutting insert to non-destructively form a geometric feature and expose the substrate and each layer of the coating; and measuring the thickness of each layer of the coating. In one example, the geometric feature is a groove with a generally trapezoidal shape. In other examples, the groove can have a U-shape, V-shape, and the like. The thickness of each layer of the coating is determined using focus variation, contrast detection, confocal microscopy, an interferometric microscopy, an imaging interferometric microscopy, or similar technique.

    Abstract: A machining tool, in particular a drill carrier tool, includes a monolithic base body extending in the axial direction which, at least in one section, has a porous or grid-like core structure that is encased in a solid outer jacket. These measures allow less material to be used, while maintaining good mechanical properties. The porous or grid-like core structure is simultaneously used for transporting coolant. The base body is manufactured in particular by means of a 3D printing method.

    Abstract: An indexable drill assembly includes a drill body, which has a head portion at the axial forward end thereof and wherein the head portion has an outboard pocket and an inboard pocket. The drill body contains an outboard pocket coolant channel adjacent the outboard pocket and an inboard pocket coolant channel adjacent the inboard pocket. The outboard pocket has a seating surface and the outboard pocket coolant channel opening at the seating surface. The drill body further contains an outboard retention screw aperture opening in the seating surface wherein the seating surface contains an outboard coolant ring surrounding the retention screw aperture wherein the outboard coolant is being in fluid communication with the outboard pocket coolant channel. The inboard pocket has a seating surface and the inboard pocket coolant channel opens at the seating surface. The drill body further contains an inboard retention screw aperture opening in the seating surface wherein the seating surface contains an inboard coolant ring surrounding the inboard retention screw aperture wherein the inboard coolant ring is in fluid communication with the inboard pocket coolant channel. The drill assembly further includes an indexable outboard cutting insert retained in the outboard pocket, and an indexable inboard cutting insert retained in the inboard pocket.

    Abstract: A cutting insert includes a polygonal body having an upper chip surface, a bottom surface and peripheral side surfaces extending between the upper chip surface and the bottom surface, the peripheral side surfaces intersecting the upper chip surface to form cutting edges therewith. A plurality of chip dividers are spaced apart about a perimeter of the upper chip surface to divide the chips produced by the cutting edges, each chip divider including a leading chip dividing portion adjacent to the cutting edge and extending generally upwardly from the cutting edge, the leading chip dividing portion having an elongated, rounded face. Adjacent chip dividers define a pocket such that the pockets are configured for promoting curling of chips produced by the cutting edges.
