A cutting tool holding device, comprising:
- a base, comprising:
- an abutting portion defined between a first wall with a mounting surface and a second wall;
- and
- a transverse dovetail groove formed on the mounting surface, wherein the transverse dovetail groove is parallel to a joint line of the first wall and the second wall, a bottom surface of the transverse dovetail groove has a depression space, and the depression space is substantially rectangular;
- a cutting tool holder having a transverse dovetail portion, wherein the cutting tool holder is abutted against the abutting portion, the transverse dovetail portion is parallel to the joint line of the first wall and the second wall, and the transverse dovetail portion is detachably engaged into the transverse dovetail groove on the mounting surface of the second wall;
- a fastening member for fastening the cutting tool holder to the base;
- and
- a pressing member installed in the depression space, wherein the pressing member having a thickness changing gradually along a direction of a length thereof is configured for pressing and positioning the cutting tool holder, the pressing member is substantially a rectangular bar corresponding to the depression space, and a ratio of the thickness of the pressing member to the length of the pressing member is 1/20.
