Review on 🔩 Metal Drill Bit Mandrels for Sheet Cutting by Tony Addis

Throw 3" in the drill Set the drill to slow speed, just as the ring appeared on the panel where I was drilling I noticed there wasn't a single tooth left All were sanded down. It was about 30 seconds of drilling. I'm past the age of consent and have been using hole saws for decades. If you want to cut holes in your Angel Food Cake this tool is for you.
