Topic tags/keywords: panel saw circular saw blade full kerf question

Hello:
I have a “Panel Pro” brand panel saw. It features a good-quality Bosch circular saw. I find that I need a full-kerf blade in order to not have it bind with the saw’s built-in splitter. I’d like some blade recommendations. I don’t have the unit in front of me (I will tomorrow)- can my Bosch saw (or for that matter, most 7.25” circular saws) accomodate an 8” blade? A cursory search online suggests that most “industrial” or full-kerf blades are 8 in.
Thanks

No, a 7.25” circular saw can not handle an 8” blade.

Read those descriptions completely. I think you may be seeing the outer rim blades for an 8” dado set. They will almost all be FTG grinds, and vary between 1/8” plates, and even up to 1/4”.

This is a Dado blade, and is available in both widths. It was the first URL that came up on Goofle when I searched 7 1/4” circular saw blade, full kerf. So Goofle needs to pay attention to NUMBERS better than it does, but it is flawed.

The problem you are seeing is the world is having thin kerf blades shoved down our throats. Cheaper to make, and they sell on the hype of geeee, you don’t lose all that material in the saw kerf, which is pretty much unmeasurable BS, so for them they use less metal, cheaper to make, and generally they cost more to buy, because they are soooo special.

I've used these in circular saws for years when I didn’t want to keep swapping blades between crosscut 60 tooth, and rip cut 24 tooth. NO they are not carbide, but they cut for almost as long as i would use a carbide blade before deeming it went to the resharpen pile. I buy 5 or 10 at a time. Now that I am no longer doing trade work, I find they last long enough that they are still a good deal for me. Taking the model number, and just searching it, may find you better deals on them.

I think if you search you will still find full kerf carbide blades as well, but make no mistake thin is in. So that sux if you have a safety device, splitter, that won’t work with the thin cut. A reasonable person would think this “Panel Pro” outfit would offer saw blades if they are selling something hard to find, but they don’t.

Thanks for your well-considered reply. Yes, a visit to Home Depot or wherever- will prove how- somehow- thin kerf blades have become damn near the only things you can buy. In fact, I could find no blades -of any size- that were not the of the ‘gee whiz thin kerf technology.” At least in the ten inch table saw world, thank goodness for the internet and the availablity for full-width goodies like the Forrest woodworker II, etc.
I’m now thinking that I might fabricate a correspondingly thin splitter for this panel saw, thereby allowing anybody in the shop to make a quick run to the local Home depot, use whatever they have, and then keep working.

Not sure what actual measurement is for full kerf on 7-1/4 blade?
But, the metal cutting blades are thicker than typical thin kerf wood blades.
Spec sheet show 0.106 for Diablo metal blades .vs. 0.065 for thin kerf wood blades. And they are available at most HD. Lennox has sells metal cutting blades at Lowes with thicker kerf as well.
The TCG grind used on metal blades is same as found on composite laminate blades, and works well on melamine laminate, even has less tear out. Can’t remember results on regular plywood, but I know it works?

Best Luck.

I don’t understand why a splitter is necessary on a panel saw. One would think that the rigidity of the frame plus the stability of plywood would obviate the need. What am I missing?

When you get right to the end of a horizontal cut, the top piece will pinch down on the blade.

Maybe you could swap out the splitter or riving knife for a thinner one. Shouldn’t be hard to make your own, if necessary.

Using the numbers still visible on the old blade, I found an equivalent NOS saw blade on ebay. Thanks all for your input!
