Thread cutting inserts and holder

[RaceDiagnostics]

I've been cutting some threads in brass lately and was pleased with the results.

The tool (that came with the lathe).

The results.

But I now want to try with internal and external inserts on harder steel but am not sure which tools to buy.

I think these will allow me to cut metric threads which is all I will need. Banggood a bit more expensive than ebay, but are they any better?

This is just for hobby use so I don't need "pro" quality, any thoughts.

I prefer full form inserts

Seller can make up mixed boxes.
I also got the 16IR set but they have quite a big minimum bore about 16-18mm? Not used yet.

I have only done through bore internal threads. If you do threading upto shoulders, safer to run away from chuck. Ive bought tools for it, not tried yet. Needs an snl tool, probably a shim and this is the only place I know of for full profile 11nl inserts

Which I bought 1, 1.5 and 2mm pitch, should cover anything I need to do.

I use Shopapt for my inserts. They've a wide selection of metric and Imperial.

Can someone educate me about AG60 vs full form inserts please?

Is the AG60 a generic insert that can be used to cut any metric thread?

 

[Seadog]

The AG60 will cut a range of thread sizes whereas the full form is one size only. It has a trimmer edge which tops the thread once you get to full depth.

It will go from 0.5 - 3mm and 48 - 8tpi according to my source
