I agree with David all good points.

I was thinking about it….
When I got my first under water fishing arrow rifle, 70 cm, total 6 ft range, I had to try the rifle and all my apartment got damaged, everything got broken a little bit….

Did you get a new drill?

Don’t sweat about the holes, Just keep the drill off the plane.

Just joking, my most usable drills are hand drills because of that reason, most damage happens to my planes by me not while flying.

P.S. hope i'm just joking, just got my first dremel...
