I've bought some on eBay... It can take a bit of searching, because
they don't always indicate "round" in their descriptions...
Typically, you'll find them in larger quantities than you might want,
however. I've got 16mm, 12mm, 10mm, and 8mm, though haven't made up
tools for all of them yet. One of the 16mm ones is currently on a tool
I used to use with HSS, and would have to sharpen the HSS disc often.
the 8mm ones are great for a pro-carver disk I have for an angle grinder
(don't recall the brand name of the pro-carver).
They aren't razor sharp when you get them because they are designed for
metal, though by putting a #10 screw through the center and chucking in
in a hand drill, it's easy to touch up the edge with a diamond
file/paddle. I've got about 5 hours on the first 16mm carbide one right
now, and haven't even rotated it yet... Touching up the edge with a
diamond paddle takes off the yellow coating though, but I don't think it
matters for wood.
The wood tool sellers make a big deal about "nano-grain", though I
really don't think it makes a difference, as we're not cutting steel
here, only wood, so even an interrupted cut doesn't cause nearly the
force or shock that a typical insert sees in metalworking use.
If you don't find any at a decent price or quantity, drop me an email...
I'll be willing to sell some of any of the above sizes for $3.00 each
plus the cost of postage. I'll sell them as I got them, so if you feel
they need a razor edge, you'll need to touch them up yourself.
Thanks

Both the Hunter and the Eliminator have left me with the urge to try
out yet another member of the latest trend (after the ci1) but prices
are still a bit steep. Both sell their tips for around 20 usd while
industrial carbide inserts can be had for about a sixth of that (10
for 35$). Problem is, the industrial inserts dont seem to be that
sharp along the edge and sharpening them seems out of the question.
Im interested to hear from anyone with positive results with a DIY
tool of this sort.
