I think this would be the right forum. I want to make my audio speaker holes about an inch wider in diameter just wondering if a dremel would be the best way and what kind of tip or if something else works better. gracias
I've had great results cutting fiberglass very neatly using one of those multifunction power tools similar to the Fein Multimaster (Harbor Freight has one that they periodically put on sale for about $35). I use the straight blade for short cuts, and you just can't miss with them. I'm probably going to wear mine out soon, because I use it for cutting and sanding on the boat.
