Claims12
A cutting knife for difficult-to-manipulate, chip-removing cutting tools that is replaceably held in a knife window (14) of a rotary-driven tool shaft (2) of a base body (1), characterized by the fact that at least one knife holder (10) that is connected to the cutting knife (9) over a predetermined breaking point (13), and that assists with manipulation, is attached to the cutting knife (9).
Procedure for fastening a cutting knife in a chip-removing tool, especially a deburring knife, in which a relatively small knife (9) is held in a knife window (14) of a tool shaft (2) of a base body (1), characterized by the fact that the cutting knife (9) is inserted using at least one knife holder (10) attached over a predetermined breaking point into an opening in the cutting or countersinking tool and is there anchored in the correct position, and that after the cutting knife (9) is anchored in the correct position, a short press on the knife holder(s) (which serves as a manipulation aid) stresses the predetermined breaking point by bending it until it breaks and the knife holder is removed as refuse.
