Dovetail65 said:What is the specific reason you would not go back to 1/4"? If it is length I get that, but that's more a function of your particular router. I find the length of shaft on a 1/4" bit is normally the same as on the 1/2" bits I use.
If it is chatter again that is the router.
Have you actually snapped a steel shank bit? I never have.
If one uses a 50mm bit in say, an OF1400 with 80mm plunge depth, you can't take advantage of the full plunge depth, it's that simple. I can't see why you would imply that chatter is caused by 'the router' of course it is sometimes true, but there are other factors to consider.
I won't go back to 1/4" because I want a beefier shank and the option for a longer shank if I need it. I left all my 1/4" bits behind and took the 1/2" ones because I'd invested lots of money in them, and 1/2" collets are easy to come by, even in Scandinavia.
