My piece of corian is now 5'x3' I want to cut it dow to 55"x25" It also has wood under the corian. Do I remove the wood or cut right through it? What tools do I need?

I take it this is an already mounted countertop?

If you can get the saw entirely to the edges,I have always used a circular saw with carbide blades,it will cut the Corian and the wood as well(look out for nails,etc)

Use a straight edge for this as there can be quite a bit of vibration due to cutting a material like this(much less if the mounting is even a little loose)

Cleaning the edges can be done with a router(also with carbide tips)and then sanding all the way down to using a scotch pad for a polished finish.

When cutting the corian use a 60 tooth carbide blade.cover area to be cut with duct tape. This will protect from chipping. Mount straight edge with clamps to keep it from moving.

Good luck

I don't think I would use a 60 tooth blade, Chuck. I've always used a 40 tooth. Cut is smooth. I think a 60 tooth could create too much heat, something you have to guard against with Corian.

Hi Harold

Been using 60 tooth for about 6 years. Have not had a problem yet. If they are good blades, they have heat sink cut in them. So do good 40 tooth.

A 40 will work fine, I like the 60 because I do a lot of trim work.

Good morning Chuck.
Are you talking about a 60 tooth 7 1/4' circular saw or 10" chop saw. I assume Op would be using a circular saw.

Luca,
If possible cut from the bottom side, chipping occurs on the side where the saw blade tooth exits the material. Not that much of a problem with Corian.

Good morning Harold

Talking about circular saw. My chop saw does not cut that deep. Neither does my radial arm.

Good point to cut from bottom if possible. If not, protect corian by padding saw base with tape or piece of cardboard.

In addition to the great advice already given I lay down a strip of painters tape if I have to cut from the top. Make your mark on the tape and then cut right through it, reduces chipping too.
