I'm just wondering where this Delta blade fits into the mix. *The price

I have the Delta 35-7670 8-Inch Stacked Dado Set that Amazon carries
(there is another set by DeWalt which looks identical) and it's worked
really well for me. I haven't used it much, but I used it to put 1/2"
grooves in some pressure treated SYP, and they still work fine on oak.
I have a 35+ year old 9" Delta contractor's saw, and even though my
saw may be underpowered for the blades, it still cuts great and gives
me a nice smooth bottom.

The included shims are metal, which I like, and the case is nice. It's
a plastic "brief case" style case with secure wing nuts to hold the
blades and chippers in place, and the shims are in little plastic
pockets in the case.
