I tried the diamond wheels & am not real impressed with them, it did good at first, but not as good as I had hoped for. First couple of flints it cut like butter. By the 9th flint I have having to really work it hard as if the disk was worn out. Will try it again when I rework some more flints. Maybe I had some real hard flints or maybe a bad wheel.
The diamond wheel does cut faster than the Mizzy as it has 5 times the surface area, but it is also harder on the dremel as it vibrates allot more & not as well balanced as the small Mizzy wheel was.
The Mizzy wheel still does a good job still even tho they are small & you have to change the wheel about every 12 flints or so. The Mizzy wheels are what :hmm: $5. a dozen or something like that ?
If you buy bulk flints in bags of 100 for under $5. worth of Mizzy's you can have them all with nice flat tops.
And if ya don't want to buy the Mizzy's & use the dremel, go to NAPA and get some gray Sonic Weld. With $5. of that hand kneaded epoxy you can level the tops of a whole bag of flints (100), and since it is dark gray it is hardly noticable..
