ER20 3.5mm (0.1377) AA Ultra Precision Collet

GS Extreme Precision AA Collets have a runout of only 5 microns (0.005mm) for maximized concentricity. Even distribution and minimized variation of the tools cutting edges ensure high performance machining and tight tolerances. Improved system performance and lower cost per piece when used with high quality GS chucks. The result of an improved AA collet in a quality chuck is increased gripping force, improved rigidity, decreased runout, and a renewed confidence in your collet chuck system.
