Sandvik don't only make tooling for metalwork. If you google "EOC16 collets" there are many hits, mainly concerning woodworking routers, most of which nowerdays are CNC.

It would be a good idea to look through the bore sizes of the collets and make sure a good range of sizes is present before looking for a 30 holder for them. The holders are available, but probably expensive.
