Back to the drawing board!
Ive bought a good 20 or so of these blades. So im using the blades to to cut various square Notch holes drywall, 1/2 plywood, etc. So say light to medium duty type work. The part that holds the tool in the machine keeps breaking into pieces, still cuts, but the blades are falling apart fast. I sometimes have to use pliers to removes pieces of the base of the blade from the tool. All Dewalts blades are expensive and very little value. I only bought them cause I thought they had longer life then other brands I switched to a different brands Bosh, rigid, even harbor freights. They all work better then dewalts and cheaper! Tool is good, Blades are Awful!

Bought DWA4204 and they worked as well as other brands. Far cheaper through HD than other brands.

Saves hours on shingling roofs.
I build Tuff Sheds, and found out about this blade through another crew. Cutting shingles off the edge of the roof was always a pain, especially dimensional shingles on a 20' barn. But no more.

With the time this saves, the blade AND the Milwaukee 18v Oscilating multi-tool to drive it were both paid off by labor savings in three weeks. That is a FAST turnaround in a tool paying itself off, and more than anything it is this blade that did it.

Pros - fast, effective, efficient.
Cons - will cut you like a mad mexican girlfriend if you just toss it in your toolbag. Store carefully if you keep it on-tool.

If you are doing roofing every day, you'll have to replace your blade somewhat regularly... it's basically a boxcutter on Redbull. Shingles are not kind to blades...

Not only do I recommend this to friends, I make sure I find our new forming crews to make sure they know about this blade. I was a bit irate when I found out no one had told me after months of cutting dimensionals through the winter.
