Abstract

PURPOSE: To have easy and cheap production and processing by making each wedge from a cylindrical material with its one face cut off and furnished with a slot, and by providing one of the moving pieces with a tapped hole leading to said slot.
CONSTITUTION: The circumferential part 8 of the body 7 of a cutting tool is furnished with mounting slots at even spacings and a combination of a tip 9 and wedge 1 is inserted in each slot from the side. Each wedge 1 is partially cut in the form of an arc of circle to provide an undercut for smooth work of the tip. If a fastening screw in a wedge 1 is, when a tip 9 is to be fixed, driven in the direction that this screw goes forward, a pair of moving pieces part from each other to press the tip 9 against the body 7 of the tool. Thus the tip 9 is fixed. When the tip 9 is replaced the fastening screw is loosened and only the tip 9 is removed, and then another tip 9 is inserted and the screw is driven firmly. According to this arrangement production and processing of this type of built-up tools are facilitated, resulting in a low post of work.
