Just wondering if anyone has come up with a drill bit attachment that could operate handle for can opener? Yes, I'm lazy! But on those special occasions when I have to open a bunch of veggies and fruit cans I wish I had something.
Yes. Someone jury rigged one: https://www.youtube.com/watch?v=9eK630Qm9I8
Although that video makes it look pretty smooth, manually applying power to a can opener, especially without rev control (I own that particular model of Bosch Ixo and can confirm that it doesn't), can get out of hand and might turn messy.
However, if you want to be able to open a lot of cans I would get a dedicated electric can opener, these can sometimes be attached to the side of the countertop: https://www.google.com/search?q=electric+can+opener
They're fairly simple and affordable devices, various kinds have been around for almost a century.
