Round worktop cutout for an inset bowl sink/drainer

I need to cut two round holes for an inset bowl sink&drainer in a solid wood worktop. I know that if I attempt this with a jigsaw, the edge of the cutout is going to look ragged.

If there a special tool I can hire to do this or am I just missing the point entirely? :)

does it matter what the edge of the holes look like? no one will see them as they will be covered by the lip / rim of the sink, since they will be smaller than the diameter.

but why not test it on an odd sheet of timber
Breezer is right most, sinks have a rim which will cover any ragged cuts, as long as you dont stray too far from you line. If you do want a smooth line then consider a router with a circle cutting jig or a dremel with a trimming bit and home made jig.
Thanks for the replies.

Sorry, I don't think I explained myself very well here, the sink will fit under the working surface rather then over it so the cutout in the wood is going to be exposed for the world to see. :)

I have seen them under corian but never wood, hope this is not going to be yet another new trend to contend with.

As has already been suggested a router & circle cutting guide is your only chance of getting a decent finish, you will also need to round over the top edge to get rid of any sharpness and to stop it splintering.

I would also suggest sanding and use sanding sealer to tighten up the end grain before you put on any final finish.

Not if you use the correct blade, the one that have saw teeth pointing downward which is used for laminated ( but you will need to put more pressure on the jig-saw to stop the kickback ) The only other tool I can think of is a router.
I guess your talking about a Belfast sink. This is the problem I joined this forum to post myself.

Does anyone know how to cut 45' corners in the worktop on the exposed face that will show with the Belfast underneath??????

I did it recently with a router and a corner chisel, it was o.k, but not ideal
