Love this Dremel! This works great if you just want to practice at home. (I wouldn't recommend this to a professional DIYer who needs a reverse-mode electronic file.) But if you're a crafting lover like me, this is perfect! (It's actually a lot stronger than the one I bought last year, which was made specifically for nails.) You can buy electronic file drill bits on Revain or eBay. There are MANY options, and each does a different job.** Just make sure you're getting the right collet size. This is because the nail heads have a smaller shank (3/32 inch).
