FIELD: process engineering.
SUBSTANCE: proposed holder comprises main body furnished with cutting element clamping head arranged on body end face, said body being oriented along lengthwise axis. Note here that said clamping head has a cutting tool seat confined by clamping tab and lower thrust surface. Note also that separation spline is arranged between said tab and said bearing while said tab may be pressed against lower thrust surface by clamping element arranged inclined to holder lengthwise axis and across said separation spline. To simplify replacement of cutting element, clamping element central axis forms, with respect to said holder, clamping angle smaller than 45°, in particular, smaller than 30°. Note here that clamping tab has buried recess to mount clamping element head made along central line. Note also that clamping element central axis is shifted relative to buries recess central axis in direction of lower thrust surface. Length of cutting element cutting edge defines the cut width adjusted from cutting edge apex to cut maximum width corresponding to cutting element central zone.
EFFECT: simplified cutting tool replacement.
