Carbide Tips from Hong Kong

[Fowlers FuryParticipant @fowlersfury]

"the inserts pictured are totally different. Ones a polished insert with a small rad and ones coated with a large rad."

Of course, no dispute I can see that.

"My own experience of inserts from China, is that similar geometry etc gives similar results."

Similar results doing what though? The particular application I had was to fine turn silver steel to be a precise fit in a bored hole. Those unbranded sintered tips would not allow that. I'm in no position to question whether such Chinese tips with the same tip geometry as the Iscar ones would have permitted <0.001" cuts. I haven't tried. I simply purchased the Iscar tips and found they did the job I needed.

Then as for "Try mounting a 3" diameter plus steel or hard skinned cast iron bar in the chuck, run the S7 flat out, and take a fast cut, at least 250 thou deep."

I'll pass on that. The Myford does all I need which excludes having to take enormous cuts in 3" chilled CI.

I am a regular user of HSS lathe tools but possibly due to my inept use of the Quorn to sharpen them accurately, I cannot obtain the surface finish on Ag steel (with or without Garia H lubricant) that the Iscar tips generate dry.

At risk of repitition, I was attemptng to relate my experiences in using my lathe accoridng to my particular 'hobbyist' needs. If others should find anything of value in recounting those experienes so much the better.

Anyone who has to dump their old Myford to make space can send it to me. Nothing wrong with HSS in my hands…

And throw out your lovechild of a lathe? I know the myford can do whizzbang's and more but that would be like throwing the baby out with the bath water, the real way to go about it is to get TWO lathes! Join that exclusive club and keep your precious one and only.

A word to fowler, slight off topic but, I don't know if you've heard but the court case over who owns that photograph (Ape vs photographer) has been finally settled in favour of the photographer, common sense at last.

Yes thanks, had seen that. It's on the list of urgent jobs to change from "Naruto" to another, non-copyright image.

How about a gold plated "Naruto" next to a silver plated one.?

So another conclusion from Fowler's post is that cheap Chinese inserts only work on cheap Chinese lathes! Perhaps every workshop should have one. Anyone who has to dump their old Myford to make space can send it to me. Nothing wrong with HSS in my hands…

Oh lord, what a real messed up conclusion

Ketan at ARC.

It's a fair cop guv!

The point I was trying to make, was that inserts are designed to work at certain ranges of speed/feed and depth of cut and different materials. The “gold” insert could be designed to have a minimum depth of cut of 0,3mm. I was comparing branded (US735), with similar China ones.

Check out Pierre's Garage Youtube channel for some tests on various Wild East tools. There ARE some decent tools out there but you need to understand what you are looking at, otherwise you won't know if it's any good or not.

Why, Ketan – why ?
