Topic tags/keywords: laminate countertop cutting blade tablesaw blade

I bought a vanity and top from a box store. I kept looking at the box and decided to measure the vanity and compare with the one in the bathroom. Yes…...I should have done this in the first place. The vanity in the bathroom is still in good shape but smaller front-to-back that the new one. I have some leftover countertop pieces from the kitchen and master bath remodel. I just looked at a Youtube video by a gentleman, Phil Crocket. He used a plain ol’ circular saw. Seems simple enough but he didn’t say what blade to use. I have a circular saw with just one blade and a TS with several TS blades from coarse to a 10 inch Dewalt 60 tooth ATB. Your suggestions are welcome for technique and blade. I’ll buy one if needed. Can’t have too many blades.

Use at least a 40 tooth carbide blade. Turn the top face down and cut back to front.

+1 for what jason said. Use a straight edge of some type and offset it the width from your blade to the edge of the circular saw base and cut with the good side of the laminate down to prevent tearout or chiping on it your good to go. But if you do it on the table saw you want the good side up for the same reason due to the difference in how the 2 saws cut, the circular saw cuts upwards and the tablesaw cuts downwards.

You would be better with blade with a scribing saw,they have normal blade to cut and a small four inch or so precutting scribing blade it just cuts about a few mm into the wood from below to stop it splintering when the big blade breaks through .This is obviously the best option for you if someone near you has one. I have one but am far to distant to help though I would gladly if it were practical .
In the meantime measure your circular blade depending on which way you cut to see distance from saw blade teeth to the edge of the saw frame add this measurement to your wooden or aluminium fence which you need to secure accurately . Use only a fine tooth carbide blade forty tooth minimum.
Scratch it if you can with an awl etc to break the surface of the melamine or formica fimished surface following the fence setting obviously remember to reset the fence to be dead on the cutting line if you decide to do this. Now reset it back again to the setting which allows for your saw frame to the teeth this procedure might take a good few scores so please be patient . Now when you’ve done this the rest should be easy if you don’t want to scratch or scribe it first don’t worry it should still be ok with a good sharp blade.
Don’t be nervous and once you start to cut continue without pause til the finish. I would always advise you to dummy run it all first to make sure the cable does not get in the way and even more important your fingers don’t either.Get help if you need it . It can be a bit daunting as it is noisy and frightening if you’ve never done it before but it is easy enough.I wish you well Alistair

I just finished cutting some counter tops for my kitchen. I had to do a few custom pieces and the supplier would not do special orders. As others have said, a 40 tooth carbide blade minimum. If using a table saw, have the face on top. If using a circular saw, have the face down.

Many thanks- LJer’s come through again! I think the easiest way would be the circular saw as in the video. I’ll check my blades and buy one if needed. I thought about scoring the laminate before sawing to avoid chipping. Mr. Crockett used wide masking tape to prevent chipping. I might do both. Just take my time and do a couple of trial runs, watch the cord, and count fingers when done. I’ll have to get a piece of laminate for the end cap from the cabinet shop and an end splash.

masking tape is okay and works, I use duct tape and press firmly all the way across real;ly hard so it is stuck well to the surface, then cut and take it easy and you should be fine/
