I recently bought the M18 Fuel oscillating tool and I'm on the hunt for the best blades to use with it. I've heard from someone that some Chinese brands on Amazon perform just as well as the big-name brands since they all seem to burn out pretty quickly. I'm also open to any other attachments that you think are worth getting. Thanks for any suggestions!

When they're on sale, EZ Arc blades are a great choice, either from their website or places like Temu. I've snagged some at half the price on Amazon.
Definitely try to maximize the blade's lifespan by using the entire cutting surface instead of just jabbing in one spot. Both Diablo and Milwaukee make solid options. If you go easy on them, the carbide blades should last a while!
From what I've researched, Diablo blades are known for their durability and long life. I've been using EZARC blades for metal cutting, and they hold up quite well too. Just be cautious with the really cheap bulk packs from Amazon because they might not last long under heavy use, but they're just fine for lighter materials like pine or cardboard.

Glad to hear that, I was looking for some tips on blade usage!
