I used this on 28 holes and it's still good to go. Greatly reduced the mess that would have been created. You need to clean it once and a while so you can see the pilot point but that's no biggie. Made me wish I had this a long time ago.

Thin concrete base plaster on top of drywall. Only lasted not quite 4 holes. I would think it would work really good on just drywall

I wouldn't recommend if you're cutting more than 5 holes. This thing started to dull after just a few holes and spring would not compress well. I am a California certified electrician btw
