I think you need the specific Sandvik blade. I use the N151.2-200-4E and the GTN2 tips certainly don't fit :med:

Thank you. I have ISCAR GTN2 shank and inserts. They fit together remarbly well, but ISCAR inser does not fit perfectly to cheap GTN blade and that cheap insert does not fit perfectly to iscar shank. Those are the standards.
I'll need to hunt down proper blade or shank. I see them reasonable price on ebay/amazon, but shipping etc. seems to double the price = no reasonable at all after that.

Harder than I though...looks like there are very many nearly identical looking parting off systems that are not compatible at all.
When in Sandvik T-Max Q-Cut-system...
I have N151.2-300-4E inserts and that seems to be pretty common size. However I can not find any reasonable size shank for it... RF151.23-1616-30M1 or 2020 would be ideal and 20 mm cutting max. dia is fine.
I could find a -250 series (for rare 2,5 mm wide inserts) a shank from local tool shop, but they have no inserts for it. pretty reasonable price, but inserts for that width are not that common
I could go for -200 series, but tried to google an hour and no shank/inserts at this side of the customs barrier.....
I'll probably end up going back to GTN-2 inserts, least I have one 20 mm shank for it and there are some supplies for the inserts.
I'm wondering how well (deep) 2 mm MGMN 200 style inserts and MGEHR shank would work on normal steel and aluminium (two different inser grades ofcourse).

If I were re-tooling I'd go with the GTN series. The Sandvik series are less common and command a higher price, I only got started using them as some tooling came with a lathe I bought. They ARE however very nice and available in left, neutral and right hand cutting.
The parting insert holders don't last for ever - they make them double ended for a reason :ddb: Trouble is when I've needed a new one (which has happened a couple of times) I've always had quite a few inserts in stock so ended up being wedded to Sandvik :bang:

Thank you.
I agree sandvik inserts outlast E.G. iscar something like 2-3 times and they are nice when you get the right one. For some reason grades for excotic metals (like iconel, hardened metals etc.) come available more often under Sandvik.
But my need are normal structural steels and aluminium. I'll go for GTN2.
