ABSTRACT:
Improvements in divided milling cutters comprise a first cutter half (2) and a second cutter half (6) which are adjustable in relation to each other with respect to their mutual distance and are both connected to a common sleeve (1) threadable on to and securable to a cutter spindle or the like which is preferably threaded, at least in part. To make possible a continuous or step-less variation of the distance between the cutting edge holders in a simple way even when the apparatus is mounted on the cutter spindle said second cutter half (6) is fastened to an outer sleeve (8) which is in threaded engagement with an externally threaded intermediate sleeve (13) having a substantially annular flange (14) which abuts an end or shoulder on the common sleeve. In working position all sleeves (1, 13, 8) are retained on the cutter spindle by means of a nut which is threaded on to the cutter spindle and presses against one end of the outer sleeve, possible under the intermediary of an intermediate pressure ring (19), or by hydraulic locking means.
