TiN coated Hazet

[German Satin]

I've bought Hazet 5mm/6mm hex sockets in 3/8, 8801K. Used the 5 a few times and the TiN isn't holding up too well. See pic.
Any thoughts anyone?

Normal Wear and Tear?

Very normal, the TiN layer is like an oxide layer. Just because you see the shiny gold going away doesn't mean that the hard layer isn't still there, although is does eventually wear off and has little benefit on a socket like this anyways

No problems there.

Is that wear on the TiN, or oxide from the bolts transferred to it?

Difficult to see in the photo but that was my guess also.

Thanks for the info. I assumed the breakdown of the 'gold' meant the tin had gone altogether.

Bit of both I think.

I’ve got a few of that style of Hazet bit. Most of them have the same discolouration in the coating. If you wipe them down regularly I find you minimise it, which suggests that at least some discolouration is deposits from the fastener. The really well used bits the coating is definitely worn, but this only seems to be cosmetic, and I can’t find any real wear on the bits.

If it bothers you, Hazet also offer the ‘one piece’ bits, at least in 1/2 inch drive

Doesn't bother me really as no visible wear to the bit itself. Thanks for your reply ...

Looks perfectly normal...

This is normal, no worries. Even the new ones differ in color. It is a functional coating, not a design coating.

I asked an engineer in a local manufacturer, whos company installs new drills at the start of a shift and replaces them at the end, if I should splurge for the coated drills. He said most users only need HSS, either plain or black oxide coated. He said, "You know what that TiN coating is for? It's to lift money out of your wallet."
I've heard this line repeated several times. I think it applies to other tools too.

Years back, I was using drill bits to bore out pen bodies, when turning pens on the lathe. What I found was that the smoother surface of a TiN coated bit allowed me to bore about 3x as deep before I had to pull the bit out to remove chips than the black oxide. The oxide is rougher, and clogs with chips much more easily.

Other than that, yeah, it's mostly a gimmick. On a tool that turns a fastener, reducing surface friction doesn't seem like a very useful feature anyway. That being said, my black oxide allen keys are always rusting, and having coated ones would save me from having to clean and oil them.
