Patent abstract
A rotary tapered tool holder includes a body and an adapter sleeve disposed about a portion of the body. The body and the adapter sleeve have front and rear contact surfaces with different taper angles. The front contact surfaces are optimized for an interference fit and the rear contact surfaces provide an axial stop and support band when the tool holder is assembled into a clamping receptacle. Face contact is achieved between a flange contact surface of the body and a face contact surface of the clamping receptacle.
