Yes, if your Dremel has a 1/8" collet I have never seen long bits for that small shaft. The standard electric and air grinders use 1/4" shamk bits and you can buy them many places. As a MAC dealer for decades I sold many sets and always had a set on the truck. Prices range $15-$150. I can't speak of the quality of the cheap ones but I have sold and used the expensive ones and they are a very quality carbide burr.
