PROBLEM TO BE SOLVED: To provide a rotary tool capable of replacing a cutting head with user-friendly. SOLUTION: The rotary tool (1;101) is equipped with a shank (3), cutting head (5;105) and draw bar (20;120). The shank (3) and draw bar (20;120) have cooperating members (26;126, 32). The cutting head (5;105) and draw bar (20;120) have cooperating engagement members (7, 21;107, 121) for transmitting a force in the axial direction of the tool (1;101). The stability in the cutting head for the shank is thus improved. COPYRIGHT: (C)2006,JPO&NCIPI |
