tool bit/inserts for turning

[JPB3]

Just that, I need to update my tool bit to something with readily available inserts. Be turning to a shoulder, ie; turning a thread tennon.. Prefer a 5/8'' square shank. Almost 100% stainless barrels..

What are ya'll using ?

Thanks much !

This is what I use.

If I could only have one tool/insert it would be this setup.

I really can't recommend KC5010 inserts enough. They make a wonderful chip that shoots straight down into the pan, even at the low/moderate speeds I like to run and they leave a GREAT finish.

I use these on a Boring bar
The bonus with the boring bar, I can Turn, Face, or Bore all with one tool (More efficient)
I think it is CCMT 32.51 Inserts
Fabulous cut and finish on SS, sharp enough to make very fine cuts, will curl .001" material
-------------------------------------
For making narrow relief grooves behind a thread or getting a perfect square cut right up the the shoulder
I have found thinbits to be awesome!

Thanks fellas, appreciate your input

I use a profiling VBMT diamond for probably 90% of turning, except for removing large amounts of material.
Reaches into tight spots, perfect for a quick plunge at the end of threads to eliminate the radius at the shoulder.

Just for clarity for others that might go looking for it that’s a DCMT3251LF insert in Kennametal’s KC5010 grade carbide. Calling out just the grade/coating will lead you to all sorts of tooling.

I do like that grade/coating as well and an insert I’ve been using for a long time is the Kennametal DPGT2151HP KC5010 inserts. Sharp high positive insert.

Good call out. I like those high positive inserts, they don't make chips for shit, but they have a place for sure.

@LVLAaron what were the boring bars you posted a long while back with indexable inserts? The ones that will fit in small holes.
