How to cut corian countertop for a sink
I remodeled my kitchen, and kept a cabinet with corian countertop. I need to cut a hole in the corian for a square shaped top mount stainless steel sink.

Originally, the guy who installed my new kitchen was going to remove the drawers and cut a hole after the completion, but he won't call me back.

Well, I removed the drawers and then I glued and clamp the drawer fronts on. I did a pretty decent job for a novice.

I'm ready to try to cut the hole myself. If someone knows how to help me step by step instructions on tools, blades, anything....I would appreciate your advice.

I have a circular saw that I can use.

Is this an overmount or an undermount sink? If it is overmount, you might be able to get away with a circular saw and a fine tooth blade, but I wouldn't try it personally. If it is undermount, no way.

Either way, a circular saw isn't the tool for the job. Solid surface materials are best cut and formed with a large router (at least 2hp) and carbide bits.

cut corian countertop for sink
It's a overmount and sink will sit on top of the countertop. Another forum said a carbide blade on a circular saw or router. I would do straight cuts of a square.

What are my concerns doing it myself.

Do you have a jig saw? You can cut out that top with a jig saw without much problem. Since it is a drop in getting the cut a little off line won't show. I think Bosch has jig saw blades for plastic or solid surface.

I can borrow a jig saw. Do I need a carbide saw blade too?

I'm concern with which would be best for control in cutting the opening? If anyone has cut corian themselves, I would be interested in hearing your experiences.

The Bosch blade you need is T301CHM3, but I am sure other brands have solid surface blades. That is a T style shank so you will need a jigsaw that uses T shanks. Since you are cutting out a piece of waste you can drill a starter hole for the blade to go through away from where you actually need to cut and make some practice cuts. Do not force the saw hard, let the teeth eat at their pace. If you want some material to practice on stop by a fab shop and ask for some scrap. There are several shops near me that regularly have to toss drops and shorts since they pile up so fast.
I have machined a variety of solid surface with saws and routers with no problems. But to be honest, having access to a cnc router is the best : )

I got that I will need a jig saw that takes a T shank for the blade you mentioned.

What is cnc router? Is it a special brand or are you saying a router would be a better tool to use?

CNC just means "computer numerical control." It is basically just a computer controlled router/lathe/mill/anything that you enter a program into, and then it makes all the precise cuts for you. He is just pulling your leg will be fine with the jigsaw :thumbsup:
