The quills aren’t very rigid, so if you want precise holes in metal, I’d look elsewhere. I have one from Harbor Freight, and it works ok, but you get what you pay for.
My dad has a mid-range Home Depot Ryobi, pretty much just one step up from the Harbor Freight setup. It’s not much better as far as accuracy but it has built in lights and laser centering plus changeable belts for alternate torque. You have to pound the shaft together when you get it though so accuracy isn’t amazing. If you just want to drill holes either the HF or HD would be fine, if you want precision you’ll have to pay for it.
Harbor Freight’s are pretty good I have two one is some fifteen years old, just buy a good centerpunch. Harbor Freight sell’s a pretty good spring loaded punch for fairly cheap.
One job, I had to drill a 3/4" hole through a 1" steel plate by hand after drilling a 1/4" pilot hole and let me tell you…it was about as fun as it sounds! When those things bind…
