I'm grinding mild steel welds on my bike to get it ready for plating.
I used this bit this evening. It only lasted an hour or hour and a half. (IMG:http://dremel.com/html/images/products/bits/large/194.gif) Is there a better bit? I've got some abrasive tips for the air powered die grinder, but I don't think the compressor will keep up with hours of grinding. |

My experience with the Dremel cutoff wheels is they don't last very long. The medium brown colored ones that look like something pressed together last only a few seconds cutting steel, and break very easily. The fabric-looking ones last longer, but still rarely more than a few minutes. You can actually watch the things shrink. You seem to remove about as much material off the wheel as you do steel from the weld...
There's a speed control you can get for a Dremel that will allow you to slow it down a good bit, which might help. I have a variable speed Ryobi with a flex shaft, and slower speeds seem to extend the life of cutters and grinders a bit, but only a bit. I think the slowest speed on this thing is still way too fast. My air grinder is quite a bit slower. |
