Claims

[Claims for Utility Model Registration] 1. A grooving and parting holder for carbide which attaches and fixes a long and flat plate-shaped cutting tool body with a carbide tip attached to the upper end of the front end so as to be movable in the front and back direction, and which has a substantially rectangular cross section. On one side of the rod-shaped attachment part, a sliding support part that slidably supports the cutting tool body in the front and back direction is integrally connected to the entire length of the mounting part, and the sliding support part is attached to the upper and lower edges of the cutting tool body. A side surface of the sliding support section is provided with an inclined surface that tapers toward each other from the side surface that abuts on the part, and a dovetail groove that is complementary to the inclined surface is provided on the side surface of the sliding support section and extends in the longitudinal direction over its entire length. is provided with a plurality of holes of the same diameter at regular intervals along its center line, and at least two screw holes are provided on the side surface of the sliding support part with an interval that is an integral multiple of the pitch of the holes in the tool body, A grooving and parting holder for carbide, which is provided with a tightening bolt that passes through a hole in a cutting tool body that engages with a dovetail groove in a sliding support part and engages with a screw hole. 2. The grooving cut-off holder for carbide according to claim 1, wherein the thickness of the sliding support portion in the vertical direction is larger than the thickness of the mounting portion.
