Does anyone have experience using Dremel/Foredom to refresh serrated blades? My diamond files work ok when the gullets are in good shape. Too much work when the gullets are really worn or deformed.

I'm thinking that cylinder bits on the Foredom might do the trick. Does anyone do this? Also, I'm wondering what sizes and styles (stone, carbide, etc) would be most useful to keep in the shop. I live in an out-of-the-way place without good tool stores to try things out. I'll need to mail-order across the border. Any advice would be welcome. Much thanks!

I takes a steady hand and some practice. Chainsaw sharpening bits, cylinder stone burrs, or carbide cylinder burrs are the best choices. Fine cut is for restoring the serrations to sharp. Stone cylinders are easiest to use, but wear down fast.
 
I wouldn't use the orangeish-red bits, they wear too quickly and get uneven. Not sure about other types of stone bits.
