I have a rotary tool from Harbor Freight that needs to be replaced. The plastic is cracking around the frame.

Do I go with another Dremel like tool or go with a more powerful air powered Die Grinder.

Most of my uses are grinding off rusted nuts/bolts from areas on my car that a regular grinder can't reach or might be dangerous to use. I have used my Dremel in the past to do engravings, detailed sanding and cutting plexi glass. Budget is around $100 plus or minus. I do like that the cord is more useful and easier then lugging an air hose around. Cordless would be great, but too expensive for a tool I don't use all that often.

I understand you can use Dremel attachments with the Die Grinder and get more use of it. The Dremel is around $99. THis kit from Vevor is only $70 with both an angled and straight grinder:

If you have the air compressor to power it, die grinder all the way. A die grinder will be able to push larger carbide bits that a Dremel won't be able to.

However, if you don't already have an air compressor, a Dremel is a fantastic little tool.

My vote would be air. As long as you have a big compressor they use a ton of cfms. For detail the Dremel works great. Just not enough punch for the bugger stuff.

I wound up getting a Dremel. I found a Dremel from an estate sale for $10. Works great. I didn't realize until I got it home that it's from 1987 the receipt was in the case and the chuck says West Germany on it. I used it to get some carbon off a cast iron waffle iron, no issues.
