PROBLEM TO BE SOLVED: To provide a tool clamping system that is introduced at a high rotational frequency, maintains a high quality, with sufficient tensile force at any rotational frequency, and easily and speedily performs exchange of tools. SOLUTION: The present invention provides a tool clamping system for mounting a tool 8 on a spindle shaft 1, including: an inside conical part 7; an axially supported body 2; a chuck 3 brought into contact with a conically expanded inside conical part 7 at an end portion and coupled to the spring body 2 in an axial direction; and several centrifugal force members 4 disposed on the corresponding oblique faces, wherein a force acting on the centrifugal force members 4 in the radius outside direction by the rotation of the spindle shaft is transmitted to the body 2 in the axial direction, and acts on the tool 8 toward the radius inside direction through the chuck 3. The body 2 has a spring part 14 receiving a backup force in the axial direction, and an urging force that acts on the tool is added in the radius inside direction through the chuck 3.
