This invention provides a cutting tool, comprising: a housing; as well as the tool bit holder, which may rotate, fix and may be held in the housing. The tool bit holder has a tool bit holder main body top that lodges with the tool bit main body bottom to hold the removable bit. The bit forms specifically with the knife edge opposite one side which has at least one localization selector. In the tool bit holder, the main body member has a localization member which may move with the localization selector. The localization member: sets the position, and should set in the position so that the localization member coordinates with the localization selector. In the release position, the localization member is separated from the coordination to the release position at the localization selector. The bit disassembles conveniently and allows different positions and good utility.
