I'd be surprised if there are many 1/4 shank / 2" cutters about?With my router/trimmer 1/4 collet, what would be the largest bit i should use? 25 or 50mm?
Thanks Julian. Just measured router and aperture in bottom is only 30mm any way, so 25mm it is,I'd be surprised if there are many 1/4 shank / 2" cutters about?
1/4 collet machines are normally less powerful. The shank is weaker and the friction in the collet is less than a 1/2"
I would stick with 1" even if 2" were availible.
Additionally, if you're doing this by hand, then a 1" bit will show less issues if evreything isn't perfectly level.
