The tool concept is simple and is based on the COFA system. The tool body is a single unit and the blade is pre-tensioned so that it can follow the large bore unevenness. Two screws secure the replaceable spring to the tool body. After the deburring process is completed, this spring returns the blade to its starting position. The coated carbide blades are designed either exclusively for forward or backward cutting.
This relief of the tool body is required for the COFA-X to move off-centre into the bore, as the blade cannot retract due to the pretension in one direction and orientation.
