'T - something and counting....'

[EddyCurrent]

Yes the manual is not 100% clear on 12-03 settings.
I use router cutters because wood is my material, for roughing cuts these are great, http://www.toolstation.com/shop/Powe...its/d80/sd2579 (the straight cutters)
and you can't complain about the price.
Wealden are pretty good, I just bought some V cutters from them, I'm not sure what you mean by "centre cutting", maybe you mean 'bottom cutting'; http://www.axminster.co.uk/axcaliber...tom-cut-insert I rather like the Axminster cutters too.
If the cutting edges extend below the cutter body I regard that as okay for plunging.
