Abstract:
Countersinking and deburring tool for deburring, chamfering, and countersinking of counter sunk and through holes with a rotationally actuated housing (1, 2, 7, 8, 9) and at least one blade (12) which can move within a housing shaft (9) and perpendicular to the rotational axis of the housing, the blade being withdrawn into the housing shaft (9) when the tool is stationary or rotating slowing, and being extended out of the housing shaft at a specific high speed, and the displacement drive for the blade (12) consisting of a rocker (36) which is mounted so that it can rotate in the housing and is rotationally actuated, which acts on the blade (12) with at least one actuation pin (42), characterized by the fact that the rotary actuation of the rocker (36) consists of at least one centrifugal weight (15, 16) arranged in the housing so that it can move diametrically, whose diametrical displacement in the housing is converted into a rotational motion on the rocker (36) through a form-fit guide.
