I have the Delta 36-725 table saw. It’s treated me well over the 18 mo I’ve owned it.

I originally had an Irwin Marples 80T blade, but after a few months also picked up what I recall was a 42T Diablo multipurpose bladed (I don’t have it in front of me, but I recall it has the offset teeth and the gaps between every few sets of teeth, advertised as suitable for ripped and crosscutting).

The diablo blade is my everyday blade, the marples is used when cross cutting nice finish work pieces. But, this Diablo blade is about to be pitched. I had the saw set up great with the marples. Once the diablo blade was installed, I have tried messing with my arbor nut tightness and even aligning my blade to the slot several times. I had it pretty decent, but always suspected the blade wasn’t 100% true. Last night after noticing some binding when ripping some 1×8 pine, I decided to check it out. Sure enough the back of the blade was toed in. I recently acquired a drafting square per the advise from people here. Sure enough, if I pick 4 points on the blade, all 90 deg from one another, 2 points (180 from each other) the interior of the blade is pulled in towards the arbor and a little gap is visible. The other 2 points are perfectly square with the table. I tried messing with my nut again, not improvement. So because I have no alternative, I left it and spent the next 30 min aligning my blade with the slot.

Has anyone else had this experience? I would expect it with a really cheap blade, and although this is not a real high end blade, it’s not a cheap disposable one other. I think I will be hitting the market for a new combination blade before I start building my new fireplace surround – so, any have any tips on a mid-range priced blade that is acceptable for cross cuts and ripping?

This Freud is the one I have. Have been very happy with it although I use it mostly for ply and MDF. I have dedicated rip and Xcut blades I use most of the time.

I would contact Freud about your Diablo blade. It may not be a high-end blade but, even the cheapest blades should run true.

I misspoke – its a 50T ATP model #D1050X…made in, get this, big surprise….china.

Anyway, I emailed Freud. I’d be shocked if they offered a replacement in kind or exchange, but we’ll see.

Kreg has sent 3 pockethole drill bits through the years due to me calling and telling them the little tip broke when drilling into 1xwhatever pine boards. Top notch customer service in my opinion.

So, maybe I’m dense, but how could a blade problem result in the blade being consistently toed in? Are you saying that the blade is, in essence, in a concave shape? Just trying to picture what you’re describing.

CharlesA – I would say its concave to some extent – I measured 4 points with my square, 2 of them on the same plane were concave, the other 2 points (90 deg from the concave ones) were square.

as for the toed in part – I’m sure I’m not the best at aligning the bladed, its trial/error/some luck. But, I’m guessing since I have had trouble getting it square, I could be choosing a tooth on part of the blade that isn’t square…

Register off the plate, not the teeth.

That blade sounds bent. There is such a thing, especially if it isn’t stored properly. If a blade gets laid around the shop on a flat surface or the like, maybe something was dropped on it? It could also have come that way from the factory. I’d hold out with Freud on a replacement, or you could go back on the retailer.

I have the Irwin Marples Combo 50 tooth blade. Got it from Lowes. It’s not a bad blade, and it’s somewhat inexpensive. I have several others for more specialized work.

Bill – are you talking for aligning to the slot or looking for squareness?

If you are talking squareness, I mis-spoke. I did go off the blade and situated my square between the teeth.

As for aligning to the slot, I was following the procedure outlined on this site and I believe Delata’s official procedure. I did use the teeth, but a straight one, not one of the angled ones.

I agree – I had it shipped to my house as well, so who knows what adventure the blade may have taken…it came in a plastic container thing, but still could have easily been bent.

I maybe check the marples out – I was really impressed with my 80T marples. I also wonder if one of the CMT ones would be a good economic blade to try.

Are you sure? The last I knew all the Diablo blades were made in Italy.

Direct cut & paste from the DiabloTools website


Diablo’s premium manufacturing facilities for saw blades are located in Udine, Italy.

Are you happy with the Irwin Marples 80T? I have a Marples rip blade as well as combo (forget exact tooth count) and have been pleased with both.

You need a dial indicator not drafter’s square to check and align the blade.

Hmmm. The amazon site I ordered it form said made in China. But the Homedepot pic definitely says made in Italy. I’ll look tonight when I get home.

I read some more reviews about this exactly blade (just the bad ones) and a few people complained about warping and deflection because its so thin. If its that thin, maybe its more susceptible to warping and damage during delivery as well.

As for the 80T marples, yes it was great. I only used it a few times for cross cutting 3/4” oak plywood, and the cuts were very clean. Squaring the blade up and everything was easy and fast.

Forrest blade service can flatten and retension
the plate. That’s all I can suggest.

I recently ordered a Freud router bit from Amazon. After I placed the order I noticed that the Amazon description said “Made in China” but the price was so cheap I figured I’d wait to see what they sent me. Turned out, it was a genuine Freud bit, made in Italy and works as expected. The Amazon listing incorrectly stated the country of origin.
