A cutting tool holding device (100) includes a base (110), a cutting tool holder (120), a screw element (115), a fitting positioning element (150) and a pulling element (160). The base (110) includes an accommodating groove (111 a), a receiving hole (112a) and a fitting positioning hole (113). The cutting tool holder (120) includes a holder (130) and a cutting tool receiving component (140). The holder (130) includes an engaging portion (132) detachably engaged in the accommodating groove (111 a), and a concave portion (133) communicated with the fitting positioning hole (113) is formed on the engaging portion (132). The fitting positioning element (150) is driven by the pulling element (160) to move in the fitting positioning hole (113) for pressing against the concave portion (133) tightly. The cutting tool holding device (100) has improved stability. |
