Wait, isn't that more about reducing turbulence than just cooling? The angled gate lets the metal flow in calmly so it doesn't trap air from the start. Getting the fill right seems like the main win, with less cooling issues as a bonus.

Wait, hold on, you hit rocks with a manual auger and you're still walking? My uncle tried that once on his property and it just about threw him down the hill (he had the bruises for weeks). That gas one sounds like a lifesaver for a job like that, even with the racket it makes. I'd say the power tool wins when the ground fights back.

Oh man, "hanging doors by myself" is the PERFECT example. I had the exact same wake up call trying to install a stupid pre-hung closet door. Nothing lines up, you need three hands, and the hinge pins are impossible. I went from "how hard can it be" to covered in sweat and calling a friend in under an hour. Some jobs just NEED two people.
