This system uses an ER25 tool holder, so the matching compatible collets are ER25 collets. That gives you the correct setup for selecting tooling around the cutter shank size used in flat tensile specimen preparation.
For MICRO workflows, the practical fit is straightforward, tool selection is tied to the ER25 holder, while the exact cutting tool and collet choice should follow the specimen geometry, material type, and finishing requirements of your tensile or impact samples.
