# Future milling cutters (¾ and ½) or FCS do not fit into my Makita trimmer?

The router bits that we provide for the installation of Futures or FCS fin boxes. have a fixing rod of Ø 6.25mm or 1/4'' (US metric).
These are models suitable for American machines, and therefore require a US / Metric EU adaptation cone to be used with our European machines.
This cone is only systematically provided to you when purchasing a complete Futures installation kit.
