I got this Dremel for pet care and it gets hot incredibly quickly. After Asta just flinched after using it for less than a minute, I tried it on my own nails and yes it did get hot quick and was painful. Can't blame Asta.

Now is there some tool that would not get as hot so quickly? I'd really like to grind them down. Nail clippers are somewhat out of the question with his black nails. I don't want to accidentally cut his quick (lots of quicks in this post - LOL)

TIA
