No, I left it razor sharp* after grinding and polishing and it seem to hold up reasonably well, much better than I actually ever expected.

I have reasonably nice USB microscope and tried to take the ceramic insert under microscope to compare with something like HSS blade or carbide but my usb microscope or drivers decided to give quits with the windows.
What kind of toolholder would be used with DCGT insert ?
So far the SDJC holder looks like it might work, but have not yet fond any thing specifically speced fot this insert.....
Also thinking with the light cutting pressures involved here , a simple shop made clamp might be satisfactory.....
Any tool holder specified for the more common DCMT inserts works with DCGT as well.
For those who have more money to burn these would be interesting to try:
Ref Post 28 ......
SUMITOMO DCGT 070202R-FX T2000Z 10 of em in a pack $37 + $7.99 that looks good to me !
Has anyone figured out how to use the Sumitomo catalog ? The only version I have found is based on Adobe Flash, although it might be better , for me , even after down loading the latest version of flash, its touchy and unstable and I can't yet print pages.....?
