I picked up two double packs of these the other day by mistake.
I thought they were the 40T 7 1/4" blades I usually use. The ad said they were 7 1/4" - but - all they had was 6 1/2".
They were/are on a special sale for $12.88 per two pack ($6.44 ea.) - so - I grabbed two packs without really checking them out.

It wasn't until I got home that I found out my mistake.

I can always return them - or - I can keep them and use them.

My Makita track saw uses 6 1/2" blades I can use a shim so it moves the blade away from the splinter strip so that doesn't get chewed up and use these to straight line cut rough stock.

If anyone has any positive experiences with these particular blades, I'll probably keep them.
I'm a big fan of the 40T 7 1/4" blades & if these are anything like those, they are probably good.
