Granted, power drills are moderately benign as these things go, but you can do a lot of damage to a work piece really fast if you select a tool or setting you're unfamiliar with. Which is why there manuals, books, videos, and classes to teach you.
Blogging about discoverability in the context of power tool interfaces is just peak software engineer naval gazing.
To my defense, I put a bit of wood between the metal and my hand to prevent drilling my hand but little did I know how the drill catches the steel on the very last part of the cut.
The others: very, very yes. Very yes. Jointers too. Jointers exist to show malice.
I don't remember hearing about any serious planer injuries (though I'm sure it happens), jointers on the other hand are more ornery than an alligator with all them teeth and no toothbrush.
I have a reasonably safe checklist and set practice for my jointer and I still don't trust the thing.
Drill, table saw, router, belt sander are all big no-nos.
Orbital sander is about the only power tool I'd be comfortable wearing gloves with.
Took me long enough to LEARN to wear gloves, now I have to unlearn it in specific cases :)
I have a bench grinder that I use to clean rust off various pieces of metal, and you'd better believe I wear gloves when using it. My reasoning is that the chance of accidentally touching the grinding wheel is high, and a glove will prevent most injuries, while the chance of the glove getting wound around the grinding wheel is near zero because it doesn't take much pressure to stop the wheel. Am I wrong?
Probably the #1 image I wish I could purge from my mind is that of a lathe accident. I saw the picture maybe 15 years ago, and I still remember it in horrifying detail.
Some tools really shouldn't be used until a person has had thorough safety training. The two that immediately come to mind are lathes and table saws.
