Hope this is the last on this - we being offered another seemingly good deal on the WSM 35's. BUT, and that is a big BUT, without the "S" designation !!!
Don't know where to look for this reference. My 2012 Catalogue omits that from the WSM's. Would need get a newer up-to-date version
What does the "S" refer to ???
And then how crucial is it - seeing they are the specified STAINLESS Grade ???
Apologies for the continual Q and A's
Thanks a stack in advance

Sorry about the above.
The book has it. Found it.
TIGER-TEC .......(HI-HO) "SILVER" !!!
This must be the "New Generation" better quality Inserts for sure, or U would not have included that Designation either.
So there must be a difference - but how substantial - to warrant doubling the cost - 'cos that's the current fiscal difference ???
Only U can tell

The "S" suffix on the grade is to indicate a post-coating treatment that smooths the suface of the coating for less chip adhesion (helps prevent Built Up Edge failure mode) and longer life. It's not worth paying twice as much for the newer version but does work. As the older grade WSM35 is depleted, only the WSM35S will be available and it's the SAME PRICE as the older grade. I would think you can get the older version for less because it's being closed out.
BTW, the S suffix on the grades seems to do a lot more for WKP35 than it does for WSM35 in terms of increased tool life. WSM35 & WSM35S can also be used on superalloys such as titanium, Monel and Inconel while the steel/cast iron grades (WKP) wouldn't last very long at all.

hi KEN
Thanks for this most elucidating response. Much appreciated.
There had to be an explanation, and a good one at that, which all makes sense - like a good plan come together !!!
We were lucky to get the newer version WKP 35 S whilst the older-versioned WSM are on offer at a fairly reasonable Price, methinks we should take them for starters, for our application.
Once again, a gracious THANK YOU, for the tremendous enlightenment and kind assistances. We have indeed, all benefitted tremendously from this most eloquent discourse of Yours.
