1. A cutting tool, comprising:
- a tool holder including a basic body and a support body, the support body having a slot countersunk in a front side facing away from the basic body, the slot being delimited by a bottom and two mutually parallel limiting edges;
a holder blade formed with at least one seat for a replaceable cutting insert, the holder blade having an elongate basic shape including two plane-parallel side surfaces, two opposite and mutually parallel longitudinal edges, and two opposite ends, the holder blade being detachably mounted in the slot and adjustable and fixable in different axial projection positions in relation to the basic body; and
a set-up body arranged between the basic body and the support body, the set-up body being actuated by a spring device to displace the set-up body axially in relation to the basic body against a force of the spring device, the set-up body being fixable in a desired position in relation to the basic body by a screw joint, wherein the holder blade is fixed in a predetermined, axial position in the slot of the support body by a stop member including a screw that extends through a through hole through the holder blade and is tightened in a threaded hole that mouths in the bottom of the slot.

Abstract
A cutting tool for tube cutting machines includes a tool holder and a dismountable holder blade having replaceable cutting inserts. The tool holder includes a basic body, as well as a support body for the holder blade. There is arranged between the basic body and the support body a set-up body, by means of which the support body, and thereby the holder blade, can be set and fixed in the exact, desired spatial positions in the machine without time-consuming measuring and fine adjustment operations. In addition, the holder blade is fixed in the support body by means of a single simple screw, which allows a flexible mounting and dismounting of the same.

9. A holder blade for a cutting tool comprising:
-
two plane-parallel side surfaces; two opposite and mutually parallel longitudinal edges; two opposite ends; two diagonally opposite seats for replaceable cutting inserts, the seats each having an elongate basic shape and being disposed in corners between the longitudinal edges and the ends; and two separate through holes arranged to receive a single fixing screw, each through hole having a keyhole-like contour, each keyhole-like contour including a circular section and a single elongate section having an end surface and running from the circular section to the end surface, the elongate section having a width that is smaller than a diameter of the circular section, the end surfaces of each elongate section being disposed at the same axial distance from an adjacent seat, wherein the through holes are located equidistantly from the longitudinal edges, each through hole being oriented such that the elongate section of the through hole is parallel to the longitudinal edges, the end surface being part of the through hole located closest to the adjacent seat. - View Dependent Claims (10)
