I already have cove and roundover bits in 1” radius. Is this the limit for router cutter sizes or does anyone know of a supplier of larger bits?

I could go for spindle tooling if I have to, I would prefer using the router if possible.

Above 1” router bits can become problematic. The velocity at the outermost part of the bit gets very high even at slower rpms.

Most often, the tool of choice for such large profiles becomes a shaper with a rather large head.

Router bits are out there, but, they should be used carefully.

Magnate has them up to 1.5” radius. Such roundovers are
used for bullnosing the hardwood edges of laminate audio
and video mixing consoles.

I have a 1.5” radius, 0.5” shank, Frued Bit that I use on Red Oak. Only use a bit of this size with a table mounted, 2.5 hp or larger, router.

You will need to run it at between 16,000 – 18,000 rpms. and you should trim the corners/edges off your stock at a 45 degree angle, to avoid having to remove so much waste with the router bit and then remove about a 1/16” of wood at a time in each pass.
Easy does it and you should be just fine. – Len

this was made with 1 1/4” diam. bits

build blog

i see there are maybe bigger bits now at

these bits match each other
and i am not really sure why the stock was 1” x 1 1/2”
it took to make it
my brain is turning to mush at times
so i just accepted it after trials with different stock sizes

as i say there appear to be larger here now
but at that time (couple of years ago)
that is what i could find
