Insert with Corner Radius

Insert with Corner Radius

(OP)
I am looking for an insert with 0.5" corner radius for face milling polycarbonate.  I have spoken to a few insert manufacturers and none of them have inserts with this corner radius.  Does anyone have any insights on where I could find these?  
Thanks for your help.

RE: Insert with Corner Radius

I've never seen an insert with a half-inch corner radius.

FWIW, there are round inserts, in common sizes of 1/2" and 3/4".

RE: Insert with Corner Radius

I gotta ask, why do you need inserts?  Polycarb can be cut with high speed and does much better with a higher rake angle than inserts typically have.  Why not just grind your own tool?  Any machinist worth his salt could make a better polycarb tool in less than an hour.
