Left and right are the only insert tooling I use. An old brazed carbide threading tool ground back to a 90 works for chamfering.
Most of my tooling uses triangular T inserts but I found some diamond shaped ones and a holder C type that have shown promise for heavy cuts with the less fragile point.
I think (someone correct me) triangular are the most common, you can flip them so if you don't break the tip off you have 6 cutting edges. Been a while since I ordered any but think its 4 size (fits in a 1/2 inch circle) the next number is the thickness then the 3 is the tip radius in 64'ths. The ones in the link show metric sizes Im guessing, not sure if they will hold inch size inserts more readily available here.
I've had the best luck with the smallest radius I can get, larger ones tend to chatter. I use a lot of HSS and bearly break the tip with a stone so the small radius makes sense.
There bet I really muddied the waters for you now.

Free advice is worth exactly what you payed for it.
