I grabbed one of these last time: https://slickdeals.net/f/19260334-8-97-dewalt-cut-off-wheel-3-with-fine-finish-ultra-sharp-carbide-dw8530-at-amazon?src=SDSearchv3&attrsrc=Thread%3AExpired%3AFalse%7CSearch%3AType%3Anormal%7CSearch%3ASort%3Arecent%7CSearch%3AHideExpired%3Afalse

I checked around, normal price is around $14 everywhere else (HD, lowes, walmart etc) with lowest price history on Amazon at $9.50, so this indeed is the lowest price anywhere.

Good deal, im in for one as the 3" wheels are hard to find (standard grit wheels cheap at harbor Freight but thats ALL they have just grit), thanks!

Good deal. Hard to find these cheap anywhere

$8.97 at home depot with free shipping at the moment, too: https://www.homedepot.com/p/DEWAL.../318904790

I think I might snag one for my M12 cutoff tool.. it already came with a similar one, but never hurts to have more consumables in waiting.

Amazon seems confused about this product - this is not a carbide blade... this is a diamond cutoff blade.

Does thos only work with the 3" cut off tool or can it be used on an angle grinder with some kind of adapter?

They came out of a lab rather than out of the ground. And they're very, very tiny. But "diamond" means what it says. Diamonds are expensive when you need large and high quality (and even then the price is artificially high), they are not expensive when tiny and flawed works fine.
