    Its 38mm chipboard/laminate worktop. I have a good jigsaw and router but someone said you can get a radius arm to fit to a router. Is this the best way?

    If its a drop in sink then a jig saw will do. When doing undermounts in wooden tops a circle guide works well, you can then use the cut out as a chopping board. You can buy them or it's easy to make your own, I've got a couple like the one at the bottom of this page

    I started to drill out the corners and connect up the holes with a jigsaw (down cut blade) a while back. Saves me worrying about cracks starting from a sharp sorner.

    I use a 500mm circular hole cutter. It weighs in at half a ton but by golly it does the job.

    In marking out a circle i always get a peice of cardboard and measure the radius on it. Put a nail though one end of the radius and a sharp pencil through the other and draw your circle onto the underside of the worktop that way.
