Hey Atroz,
thanks for posting the link. I think it was already mentioned in the depths of the forum. Here you obviously get more diameters choice for your bits shank.
But I don’t think that these replacement collets change anything on the main disadvantage, i.e. that they clamp the shank only in the front part of collet.
By the way, outside of the U.S. and Canada, the Makita hand trim router is sold with collets for 6 and for 8 mm bit shanks.
Also outside the U.S., you don’t seem to get the old RT0700C model without restart-preventing safety function anymore. The new RT0702C is the new model everwhere, which would need the hack to work with being switched on by a relay (and thus, with the Onefinity). I wonder when Makita will replace the U.S. model RT701C finally by this new model. After all, a device that restarts by itself after a power failure when power comes back is a serious safety risk (when used as it is intended to, as a hand router)
