Proper dremel, with a snake. I know a dremel’s a child’s toy but I have a die grinder which I never use because it’s a pain in the bum, and I had a cheap dremel which wasn’t up to much… The real thing’s just doing the same but better, but the convenience means I use it a ton and it’s just constantly handy in little ways and makes things easier.
(last used- very sticky handbrake cable being a dick when I tried to remove it. Zip, took the end off the cable, bzzzt, machined away a little off the orrible rusty fittings that were suppose to just snap out but wouldn’t, bzzzt, bit of rust surface cleanup… All the things that make a simple job a pain, defeated, with no need for an air hose, easy access with the snake…)
