Title: Tool unit with cutter head

Abstract: A tool unit is guided by a handling unit movable in several planes for cutting out recesses or bores and de-burring the work-pieces in one operational step. A de-burring cutter is mounted in a support arm for the tool which is movable about a central axis and is engaged by two spring arrangements disposed on opposing sides of the support arm and is returned to the original position following displacement. The springs of the spring arrangement can be replaced to adjust the spring pressure to various work materials and work-pieces. The cutting angle of the tool cutter is set automatically via the pressing force. Radial movement of the cutter is possible as are resilient deflection and precise return. A spring pressure pin arrangement is provided for balancing the cutter.
