Someoneon here linked a tool that cuts PERFECT circles. It was an attacent for a drill. Had a shield to block the saw dust and everything.

Can someone link it or find it? I'm on mobile and can't use the site so well

Yes. Thank you. Making speaker rings with that difficult?

Damn that thing is awesome! Ive never seen a hole saw that size. Kinda pricey but sweet. Looks like itd make speaker rings a breeze, no more multiple passes with a router, just cut a bunch of circles out, then size it down and cut out the centers for rings. 

You wouldn't be able to do a flushmount ring though.
