I have one of these power craft routers but it only uses 6 or 8 mm bits. All the ones in the stores are slightly bigger then 6mm. Can I get an adaper in the UK to use these normal 6.something bits?
I'm not familiar with that particular make of router, but it sounds like you need a 1/4" collet that fits your router and will allow it to use the 1/4" router bits (nice picture to explain what I mean here). Tooled-up.com sells these, but I don't know which one will fit your router. I'm sure 8mm to 1/4" collet adaptors exists as well. Hope this helps a little.
More then you know, I didn't know you could buy the collets separate, looks like I need to work out the collet size and order a 1/4 inch (bah stupid uk with its cm/mm measurements.
