Feature:1. ACCURATE TAPER: Morse taper is an international standard for taper, used for a tight fit for accurate positioning2. TRANSMIT TORSION: Due to the small taper, a certain torsion can be transmitted, useful and practical, very convenient3. EASY TO DISASSEMBLE: The principle of friction is used. Within a certain range of taper, the workpiece can be disassembled and assembled freely, and at the same time will not affect the use effect during work, such as a taper shank drill for drilling. Good on taper shank after the drill, the drill bit can drill the workpiece out of the required hole, and there will be no rotation at the taper shank4.
