Abstract
A cutting tool holding device includes a base and a holder. The base includes a base body and an inserted bore. The base body includes a central connecting surface and two positioning surfaces. A lateral edge of each of the positioning surfaces is connected to the central connecting surface, and the two lateral edges are defined as a first lateral edge pair. The holder includes a disposing head and a shaft. The disposing head includes a head body and a tool bore. The head body includes a disposing surface and two bearing surfaces. Two lateral edges of the two bearing surfaces are defined as a second lateral edge pair. Two extending lines of the two lateral edges of at least one of the first lateral edge pair and the second lateral edge pair are close to each other.

A cutting tool holding device, which is applied for holding a cutting tool, the cutting tool holding device comprising:
- a base, comprising:
- a base body, comprising:
- a central connecting surface;
- and
- two positioning surfaces respectively located at two sides of the central connecting surface, the positioning surfaces being relatively inclined to define a positioning space, wherein a lateral edge of each of the positioning surfaces is connected to the central connecting surface, and the two lateral edges are defined as a first lateral edge pair;
- and
- an inserted bore penetrating the base body;
- and
- a holder inserting the inserted bore and configured for the cutting tool to insert thereinto, the holder comprising:
- a disposing head, comprising:
- a head body having a working side and a connecting side and comprising a tool bore surface, a disposing surface and two bearing surfaces located at the connecting side, wherein the tool bore surface is located above the disposing surface, two lateral edges of the two bearing surfaces are respectively connected to two sides of the disposing surface, the two bearing surfaces respectively correspond to the two positioning surfaces, two side edges of the two bearing surfaces are respectively connected to two sides of the tool bore surface, the lateral edge of each of the bearing surfaces is longer than the side edge of each of the bearing surfaces, and the two lateral edges of the two bearing surfaces are defined as a second lateral edge pair;
- and
- a tool bore penetrating the head body from the working side to the connecting side to form an opening on the tool bore surface, the tool bore being configured for receiving the cutting tool;
- and
- a shaft connected to the disposing surface of the head body and configured for inserting the base;
- wherein two extending lines of the two lateral edges of at least one of the first lateral edge pair and the second lateral edge pair are close to each other.
