Excellent blade at a great price
Bought this for my 18v cordless firestorm circular saw. I've already used it on 2x4s and plywood, and it cuts quickly, cleanly, and with a smaller kerf than my 7 1/2" circular saw. It is still a rough cut blade, so you may have tear off, so know that going in. I'd knocked some of the carbide bits off my old blade and while it still cut, this is a huge improvement, even from when my old blade was brand new. Highly recommend this blade.

Well worth it!
This is a fantastic blade. I use it with my M12 Milwaukee circular saw. I will for sure get another when this one wears out. I've cut a lot of 2x material as well as 3/4 ply and MDF. Highly recommend. I love Irwin paddle bits as well.

Much better than blade that came with my saw
Used to cut plywood and 2x4s so far. Clean cuts and easy handling. Better quality than factory roybi blade.

Je recommande pour B&D.
J’ai cherché en magasin une lame qui fonctionnait sur ma Black&decker a batterie , je n’ai point trouver mais cette lame m’a vraiment surpris Elle est plus silencieuse que celle d’origine et coupe merveilleusement bien rien n’a dire.
