Something you might try.

I examined on of the new cnc drill pointers that "honed" the
drill after sharpening. Turned out they used an abrasive brush.
Brush had blue plastic bristles. Located what appeard to be the
same bruch in a local hardware store. Tried using it on regroud
drills and HSS lathe tools. Does a wonderful job of honing, much
better than I can do by hand in just a few seconds. I don't
think the hardware store abrasive brush would work with carbide
[I will try later today] but there should be plastic brush with
SiC [diamond? borazon?] in place of AlOx abrasives. Something
better than visegrips may be required to hold the inserts. Whats
your volume?

Hello,
The shop that I work at has special order carbide inserts, and due to
heavy feed to speed ratios on our machines, we have found it necessary
to hone the inserts.
