Abstract: This invention provides a tool clamping/unclamping device which allows a tool to be replaced simply and securely by another one in short time, and which prevents a lock nut from being loosened, from yielding a difference in phase, and from dropping off with respect to a main shaft. The tool clamping/unclamping device comprises a tool urging means for holding a tool holding member in its clamped state, a nut positioning means for adjusting the lock nut in its phase in rotation angle position with respect to the main shaft, a nut drop-off preventing means for regulating the amount of rotation angle of the nut, a nut loosening detection means for detecting the position of the nut in the direction of the main shaft, and/or a locking mechanism for engaging a steel ball urged by a spring with a lock hole to thereby lock the lock nut in the direction of rotation.

Abstract: A portable tool for milling a chamfered edge on a workpiece, includes a cutting attachment installed on a motorized drive unit. The cutting attachment includes a rotary milling cutter partially encircled by a hood element that carries a V-shaped guide structure adapted for sliding engagement with edge areas of the workpiece. The hood is attached to the motorized drive unit by an eccentric cam means, which can be adjusted to vary the penetration distance of the milling cutter into the workpiece. Various cutting depths can be achieved by adjusting the hood in relation to the rotational axis of the motorized drive unit. The V-shaped guide is arcuately adjustable to vary the slant angle of the chamfered edge independently of the cutting depth adjustment.
