  • Patent number: 11806791
    Abstract: A tool system for machining includes a tool body that has a first end for connecting to a machine tool and a second end having an end face on which a seat for an interchangeable cutting insert is formed. The cutting insert has an underside formed as an abutment surface, a top side formed as a rake face, and an encircling side face formed as a flank, and a cutting edge is formed at a transition from the top side to the encircling side face. The cutting insert is arranged on the seat such that the top side extends perpendicularly to the longitudinal axis of the tool body and the cutting edge protrudes beyond the outer circumference of the end face of the tool body in a radial direction with respect to the longitudinal axis with two usable cutting corners and cutting-corner portions adjoining the latter on both sides.

  • Patent number: 8042437
    Abstract: A tool structure contains a first part having an oval end section with regard to an axis of symmetry in a direction of a maximum height and an axis of symmetry in the direction of a maximum width, and a second part having a recess accommodating the end section via mutual contact surfaces. The tool structure has a clamping element for the mutual clamping of the parts and mutual contact surfaces that are restricted to in each case four spaced-apart surface sections. These surface sections are disposed symmetrically with respect to a circumference of the end section such that a center point of a straight connecting line of the starting and end points of the respective surface section is at a normal distance b1 from the axis of symmetry and at a normal distance h1 from the axis of symmetry, h1 being greater than b1.
