Hey, thanks for the input. I will look into that!
I looked into what you'd mentioned above. Them die grinders are just supersized Dremels! I am going to procure one of these just to make my life easier!
Big dremel: exactly. But really it is a case where power makes *all* the difference.
I started buying a dremel brand oscillating saw, it was a total joke, bogged down and overheated just starting to remove rotted wood. Returned and got the highly regarded fein and same deal, was underpowered even for removing rotten wood so returned it too. Ordered the bosch die grinder and some cheap burrs and it made short work of everything. My burrs can literally cut through a file, they laugh at wood. Very very nice for smoothing raised welds.
Die grinder is to dremel as a jack hammer is to a plastic fisher-price jack hammer. You need to get decent tungsten carbide burrs, the chinese set I got on amazon for $24 have held up really well, I thought I'd have worn out some by now but they seem to last well for me. I am careful not to let them get hot, they get hot you will melt the carbide and they'll quickly die.
But... its a powerful motor in a small package. Be extremely careful and be prepared and dressed for burr to explode at any moment. I wear goggles and a face shield and all my rawhide welding clothes. You only put it into a corner once and then you'll have some respect. Rule is to use the lowest speed that will cut nicely. Be careful of the extended reach burrs because if you press hard they bend and they'll self destruct.
I once used the die grinder to casually hone down a raised section of dried filler in a window sill. Didn't wear my welding gloves... that afternoon my hands were all red and puffy from all the high speed micro splinters. Never even saw the splinters but my hands were sure angry and this was just filler.
Just saying: I don't think I've ever been around such a sick malicious tool as a die grinder. Its very good but its also very bad.
