I have an Ameritool, so we are talking small blades.
I have a 3 or 4" plus a 5". I also have those cheap, thin crimp blades. I went to use the brand new 3" and the cut bogged down in the middle of the cut. I scraped the stickers off, but it still bogged down. OK. I put the brand new 5" in and after about 1.5 inches, the cut bogged down again. I had scraped the stickers off before I started. It cut like a champ before it bogged. Don't know what was going on. I put on a new crimp blade and it cut just fine.
Any ideas what it could be?

You didn't mention that the 4" bogged down. Is it an MK 303, too? Is it new, too? The only thing that I can think of is that the depth of the sintered diamond means that the sides are rubbing against the cut. If so, extra care in feeding the slab straight on at the blade should reduce any friction.
I've thought of buying one of the smaller MK 303s for my Ameritool trim saw, so I'm interested and hoping that a solution can be found.

Sorry, 3 blades total, 2 were 303s and one was crimped.
Both of the brand new 303s bogged down. I tried lots of stuff, but with every cut, it would only go so deep and virtually stopped. They cut fine up to that point.
I think I was cutting pretty straight, not bending the blade like a crimped one can.
I should mention- I have used several 303s before with no issue. I like the blade. That's why I buy more, but this really has me bugged.

My saw dose that but my belt is slipping Have not changed it yet I sure hope that's not the case- it's a sealed unit. But, I don't think it is, especially since the crimped blade runs fine. |

The Ameritool is direct drive, so no belt to cause what you're experiencing. Pardon me for asking this, but is there any chance that your new blades slowed down when they hit harder areas of the slabs? Or perhaps the new blades just need some breaking-in?

I go through a lot of 8 inch MK303 .032. They are not all the same. Some are thicker than others. I recently had a big problem with a 14 inch MK301. The center hole was off. I would check your 303 to see that is spinning without any wobble and that the diamond is wearing evenly. My trim saw uses a one inch arbor and I can get a blade for half with a 5/8 and grind it to 1". My holes aren't perfectly centered so the wear is uneven but I can accept that because of the cost
