[tfscott]

Hi, i'm after a double bearing router bit, for the router table (top and bottom bearings) where would i buy this? Carbatec does not seem to stock them!

Happy to purchase online, thanks!

Down Shear Trim Router Bits with Upper Ball Bearing by Amana Tool (http://www.amanatool.com/routerbits/down-shear-trimmer-47094.html)

[_fly_]

isn't it just a bottom bearing bit with a top bearing slipped over the shaft and a fixing collar to hold it there.
take the bearing and fixing collar of another bit and put it onto a bottom bearing bit.
now you have one top and bottom.

I've been looking to get one of these for a while, but haven't got around to it yet.

Its a bit I'd use a lot, so worth paying a bit more for quality.

Something like this:

Katana® Rabbeting Router Bit Kits, Round Nose / Core Box Router Bits, Flush Trim Router Bits (http://www.mlcswoodworking.com/shopsite_sc/store/html/smarthtml/pages/katana_bits3.htm#kt_flushtrim_topbot_anchor)

Of course, there are also dual bearing compression bits available for best possible cut quality (e.g. Whiteside), but these are very, very expensive.
