Does the drill bit need to be toiveld?
It’s a good question.
I bought it in a houseware store that has a Mikva so I did.
If used for apples that are edible when raw, it probably needs a brocho, but AYLOR.
Don’t let the drill bit sit wet - they rust very quickly.
Also, as it must be said: power tools are not toys, and you can seriously injure yourself (or worse) using them. “Don’t try this at home”.
It’s quite easy to stab yourself if you are not careful.
