According to my paper copy of the catalog, the only Imperial sizes they make are 1/2", 3/4", 1", 1-3/8"
All it shows for Metric is 17mm and 30mm, which I find curious.
Apparently the OF2200 is "special", since neither of the smaller routers get Imperial sizes?
There is however an adapter plate that will accept Porter-Cable style bushings. As far as I can tell, it is only sold as part of the accessory set, for the OF2200. May sold as a spare part through the E-Kat system?
The OF1010 has the most, which makes sense. 10.8mm, 13.8mm, 17mm, 24mm, 27mm, 30mm, 40mm.
The decimal sizes are a bit confusing though, why? dead-on 11mm would be very close to 7/16", but still a few thousandths small. 13.8 is over a mm larger than 1/2". I could see it if they were sold at a metric size that was equivalent, but they are not.
The OF1400 only shows a few too. 24, 27, 30, 40
