10pcs Sandvik Carbide Thread inserts. On the back they say UN 28 S10T. External.

10 pieces of Sandvik carbide threading inserts unused. R166.0G-16UN0F-280 S10T P10. They are lay down style inserts but are thicker than other inserts this size(Vardex, Iscar). I think you will have to have a Sandvik holder to use them. I hope you can use them. Thanks for looking.
