I’m sure those will work great. I typically use Dremel 420 (ayyyy) heavy duty cut-off wheels. I used to use the Dremel 409 wheels that came with the tool, but I’d usually use up 2 or 3 of those on the simplest of jobs. On the other hand, I completed an N64 trim on a single 420.
Those diamond wheels look like they’d last a lot longer.
