STS TOOLING SET COLLET AND 3 ER 20 CHUCKS
STS TOOLING SYSTEM
This special set of tools is for setting up a tool library. The R- 8 collet has a precision ground flat end designed to seat perfectly against the ground flange on the ER 20 collet chuck. This insures that all your tools can be set a precise length and interchanged with no deviation. The set is especially valuable for those with a power drawbar for rapid tool changes.
