At the time of arrival the tap and die were in good shape. I can_ say that about the plastic case. All four corners were CNN bent m and one of m them m was cracked bad enough to limit the life of the case.
diciamo che la qualit degli utensili per filettare buona ci che non ho gradito il fatto che mentre nel titolo dell'inserzione c'e scritto "cassetta in metallo" nella realt gli utensili sono arrivati in una cassetta di "plastica" per di pi molto ma molto economica.
For the price of _65 it's good value for money , the case holds the bits well and feels sturdy. I am concerned that this won't last the test of time but that said its a quater of the price of a good set. I'm not sure if it is tungsten .... as no markings .
It's not a top quality set, but that being said it will probably get you through when needed. I use almost daily at work and only one of the small taps had broke. So I really can't complain on the price.
