Tool holders and workholding are not single pieces. As assemblies each component must be qualified and properly used. Single piece cutting tools require a tool holder which adds variables and increasing chances for operator error. If all components are to specification, properly maintained and properly assembled, you should be measuring operator compliance not component quality. A single component with loose tolerances can play havoc when measuring assemblies and their performance. Part of the rational for measuring and monitoring tooling and cutting tools should be to replace non performing, worn or out of tolerance components. It is possible to have a collection of components that has little chance of delivering the proper solution for the job.
