FIELD: process engineering.
SUBSTANCE: rotary reamer (20) comprises, in fact, cylindrical shank (22) with lengthwise axis (A1) and multiple radially displacing and, in fact, axially extending clamp tabs (38) and cylindrical cutting head (24) with central bore (58) and multiple axially extending cutting edges (62) with cutting OD (D). Central bore (58) has multiple spaced in circle and alternating sectors of bores (70) and recess (72) of bores. Note here that every sector (70) of bore has external clamping surface (74) inclined outward to get in clamping contact with internal clamping surface (40) of every clamping tab (38).
EFFECT: adjustment of clamping contact forces and cutting diameter, ease of withdrawal and replacement of cutting head.
