Claims

[Scope of utility model registration request]

A base, a workpiece holder attached to the base, a tool head fed on the base toward the workpiece holder, a tool spindle attached to the tool head, and a speed suitable for boring the tool head. A variable speed feed device that can switch to a speed suitable for reaming after moving a certain distance and feed the tool, and a variable speed that simultaneously switches and drives the tool spindle from boring to a rotation speed suitable for reaming. A machine tool comprising a rotary drive device, a reamer shank having a shank portion attached to the tool spindle at the rear end and a reamer blade portion at the tip portion, and a reamer blade portion at the tip portion of the reamer shank at the rear end portion. A boring reholder having an end surface in contact with the reamer blade and having a boring rebit attached to the tip thereof, and a fixing means for coupling the boring holder to the tip of the reamer shank such that the end surface and the reamer blade are in contact with each other. A machine tool that combines a boring tool and a reamer.
