That WMP20S grade is available in CNMG, DNMG, SNMG, TNMG, WNMG, and VNMG in negative rake inserts. In the screw-down positive rake, it's available in CCMT, DCMT, SCMT, TCMT, and VBMT shapes. There are several chipbreaker choices in each.
And what DaveH says about the holders is true. If you are buying any make sure they are an ISO standard rather than proprietary. You can run anything you find by me if in doubt. I may know something about the technology and terminology. ;)
BTW, if I ever run low on any insert style (not likely) I'll be stocking up on everything in that grade because then I'd have ONE grade for everything except cast iron. And for the little bit of that I rarely see, I'll either use up the remaining flat-top CNMA/DNMA inserts I have or just limp along with the WMP20S.
