CUTTING TOOL Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: cutting tool has an arc wire member of circular cross section which, in turn a cutting part extending above the holder. The longitudinal axis of the cutting member is located in one plane perpendicular to the bearing plane of the cutting tool. The concave side of cutting member is positioned to face the bearing surface. The free end of the cutting member is located on the side of the end of the holder for extending above it. An undercutting facing the holder is made on the cutting member and increases from the convex side of the cutting tool towards the concave side. The end of the cutting part is made in the form of a convex cylindrical surface which generatrices projected on the bearing plane of the cutting tool are located at a sharp angle to the projection of the longitudinal axis of the cutting tool on the bearing surface. A groove is made on the convex side of the cutting member along the cutting edge. EFFECT: improved structure. 3 cl, 2 dwg
