fwiw,
I thought according to this old thread blade thickness was according to the core, but I just spoke with MK and it is indeed the kerf.
I've been through a bunch of MK blades over the years, generally satisfied. Replacing a 303 6" trim saw 0.032 blade, the new blade just seemed thin. mic says the core is 0.024 and the kerf 0.029" and I notice that the part number on the blade doesn't match the box. Wondered if I had a counterfeit or something so I called.
Thickness is meant to measure the kerf not the core. "the amount of material you'll remove."
All their (303 but assume others) blades are made in Indonesia.
part number on the blade sticker - was actually the part number for the sticker! (153690 vs 156907)
When pressed if 0.029" is within specs for 0.032 blade, I couldn't get an answer. That is like 10% less diamond so it'd add up over the course of production. Curious if folks have other new blades how they measure.
Might have to try some other unbranded blades again.

Just received a couple new 10" 303's that measure 0.054" for the 0.050 blade and 0.044" for the 0.040 blade

I bought an 8 inch .032 blade with a one inch hole and it was definitely thinner than what I was use to. I have been buying the same blade from Amazon with a 5/8 inch hole and reaming it out. Since the inch is an oddball they cost about 60% more than the 5/8 hole. most recent purchase was 3 weeks ago and it was as thick as what I bought in the past. Maybe I got older stock. I don't like the additional flex of the thinner blade when trimming. I bought a one inch hole MK303 .025 from Amazon some years ago because it was cheap and now is $5 less than the .032.
