I did a vinyl job on some Dibond it required to be cut into 3 separate sizes. I cut them with a circular saw with a fine blade with 180 teeth. After the customer picked up the signs, I noticed that the aluminum off cut that I had was delaminating from the core, I was able to just pull the aluminum away from the core with out any problem at all. This is the first time I have used this product and now I'm concerned that it will fail. Any one else had any problems with this product.

Put the paneling fine tooth blade into the saw backwards, it will move fine but.. it will greatly reduce the vibrations that could delaminate the substrate.. it will not pull up on the material,, instead it will rub the material away,, do this with all soft thin substrates..

Thanks for the tip Curtis. I forgot to mention that I do have the blade in reverse. the aluminum delaminates so easy it just falls off. I will be calling my suppler to have a look at it.
We have been using dibond for some time now...I love it for many applications. When cutting it, I use the coarsest blade in whatever saw I happen to be using at the time. Both my cicular saw and my table saw have carbide blades, around 36 teeth I think { labels are worn off and I don't feel like counting them right now} and I have no problems except for a little roughness which I file off. When I first tried to use a jig saw to cut out some fairly small letters, I used a metal cutting blade and ran into the same problem that you encountered. Switched to a coarse wood blade and it worked like a damn. Then i read the instructions that came with the Signply and lusterboard that we also use a lot. Said to use coarse blades for cutting because a fine blade generates too much heat! Just proves that when in doubt, read the instructions! Hope this helps. Dibond is a really good and versatile product, and you REALLY appreciate it when installing a 24x16 foot sign 30 feet up the side of a building, as we did this year.

We've cut a LOt of dibond in the last 2 years, using 40 tpi carbide blade in panelsaw, cutting using front of blade, I also use a file to remove the burrs... quick job... I've never had a hitch, and up until now not a doubt......
