Also "used" in this context clearly just means "spinning". I did a modest project the other day involving my electric drill. It involved 20 holes, each hole drilled in two steps (pilot with a jig in place, full depth with the jig removed), for 40 spins.
I'll guess that each spin took about 3 seconds (because that makes the math easy), so 2 minutes total. I couldn't exactly share the drill with a neighbor in the approximate hour that I spent measuring and repositioning the jig between uses.
In the context of duty cycle lifetime, maybe 8 minutes isn't that low -- but I am definitely using it for more than 8 minutes.
- phaedrus 5y agoUsing a hole saw and cutting into metal, I'm pretty sure I could spend 8 minutes per hole. Of course I prefer to use the drill press for this, but some projects can't fit and must be done with a hand drill. Then there's the grit wheel or flap disc, which might have me axially loading the drill for 30 minutes at a time (such as for stripping paint or sanding rust off an iron engine block). I think they must be including a lot of people who buy or receive a drill as a gift and never use it at all, to get to 8 minutes average. I do find it believable that the cheaper ones might have a design life of 8 minutes, but that's a sad state of affairs.
- amalcon 5y agoYeah, that was just the most recent project. When I had to drill through tile back in November, it was definitely several minutes per hole (on the slow speed dictated by the special tile bit). You're probably right about the stat including people who never use the drill at all, or only ever use it to tighten screws.
