One of the Bosch 1600 model accepts a 1/2 inch shank size (12.7mm) and another accepts a 12mm size. The CE version only accepts the 12mm version. So be mindful of these little details if buying a new router.

Hope you find a solution.

I have two 1600CE routers. First I purchased locally a plunge base GOF1600CE and half year after I purchased the fixed base GFF1600CE. Same stuff just with different base. Both of them came from factory with four different collets: 1/2 in, 12 mm, 1/4 in and 6 mm.

CE version can come with both versions, at last in some regions.

Regards.
