FIELD: apparatuses for manually cutting tubes, possibly used for mounting pipelines, for making different articles of tubes. ^ SUBSTANCE: cup like detachable body of unit for mounting cutting tool is mounted by means of annular dent engaged with annular groove on outer surface of tube cutting tool body whose both portions have dovetail joint. On end of said joint at side of mounting cutting tool there is helical duct for placing pin fixed to cutter mounted with possibility of axial motion in radial groove of bottom of body of cutting tool mounting unit. Screws arranged in pairs by angle 120° are used as members for fixing body to tube; said members have in outer surface flats with dial corresponding to standard diameters of tubes. At least one lever is arranged in openings on outer surface of cup like body for rotating mounting unit of cutting tool. ^ EFFECT: improved manufacturing possibilities of cutting tool, possibility for accurately cutting tubes in wide range of diameters. ^ 3 cl, 4 dwg
