Not trying to hijack Parker, but these are my homemade carbides.
(l to r) first three are made with the solid carbide tipped lathe tools like Mutt was talking about , last two are with inserts, I messed up and ordered inserts with a negative rake, make sure you get them with positive rake, I have some more ordered that will be in this week. I attached to handles and installed golf grips, I even have an expensive "Ping" chisel
Atach them any way you feel comfortable in using.
