I. TOOLHOLDERS - technical information

toolholders for threading
Toolholders for threading.
Inserts with holes designed for external threading with thread pitch up to 3 mm (of various producers) can be I.
installed on the PER/L... 16K toolholders. Thanks to their appropriate seat shape and lever fixing system the
triangular cutting inserts of the 16 mm side length (IC=9,525 mm) are positioned and fixed properly independently
of their thickness and the hole diameter. The cutting tool is equipped with a shim that provides: - protection
(in case of insert’s damage), - correction (of tool geometry).

Definition angle - l .
