Claims

[Scope of utility model registration request]

The tool holder is equipped with a tool holder that is attached to the spindle of a machine tool, and a non-rotating support member that rotatably supports the tool holder and engages with a fixed member of the machine tool. A tool holder unit in which an oil supply path for introducing oil into an oil hole of a rotary cutting tool attached to the tool holder is formed in a non-rotating support member and a tool holder, respectively. In addition to fixing the wheel, an axial flow chamber is formed on the inner peripheral surface of the corresponding non-rotating support member, and the axial flow pump chamber consisting of the impeller and the axial flow chamber is connected to the oil supply path on the non-rotating support member side and the tool. A tool holder unit with a lubrication device, characterized in that it is interposed and connected to a holder-side oil supply path.
