发明名称 Collet for a square-shank tap
摘要 A collet is designed for a tool having a cylindrical shank and a square drive at the rearward end of the cylindrical shank. The collet includes a collet body having a plurality of radially compressible collet segments. An axial bore is formed in the collet body for receiving the cylindrical shank of the tool. The tool is secured in the axial bore by collapsing the collet segments around the cylindrical shank of the tool. A grip-forming slot extends through a midsection of the collet body and communicates with the axial bore so as to receive the square drive of the tool when the tool is inserted into the axial bore. A pair of gripping surfaces are formed on respective collet segments on opposite sides of the grip-forming slot for gripping opposed surfaces of the square drive when the collet segments are radially collapsed to prevent radial movement of the tool.
