Router collets

[Arkade]

Hi
I recently picked up a Katsu 101750 trim router - and have a few questions..
Stupidly I got the 'euro' version with 6,8,10mm collets - so
Is there anywhere in the UK that sells metrics bits?
Can I get a 1/4 collet for the router? the same company sell replacement 1/4 collets for the 101748 which is the UK version - but I'm not sure if that would fit mine?
Also the length of the 6mm collet is longer than the 8 & 10mm - is that just to provide a more snug fit?
Sorry for the barage of questions I have no experience with powered routers
Any help would be great
Thanks!

You can buy a complete set of collets that includes 1/4" and 3/8". All the Katsu type use the same collets.
