An insert-detachable tool is provided to contact spot facings with a pressurized portion of a clamping screw safely by diagonally crossing a center shaft line of the spot facings and a shaft line of a screw hole. An insert-detachable tool comprises holders(10), and head members(30). The holders have a clamping screw(50) with a shaft portion(51) and a pressurized portion gradually extended into the holder or from a first jaw to a second jaw, and a screw hole capable of combining with the shaft portion of the clamping screw. The head members include an insert mounting sheet capable of mounting an insert having a cutting blade on the front end of the holders, and the first jaw with a clamping face and the second jaw with a base face. Spot facings(45) are placed at the first jaw to receive the pressurized portion of the clamping screw. The center shaft line of the spot facings and the shaft line of the screw hole are diagonally crossed each other. |
