MMMmmm damn. Slow start and bad start.First one, the writing that is on the box is not for the insert shown in the photo next to it. The box is a milling insert, for a facemill.
The picture does indeed show a threading insert. From the picture, it could be an external left hand or an internal right hand. More than that, it is not possible to say. Most common/useful threading insert is an external right hand and it is not that unfortunately
The second one is very specialised, for Iscar's mini tang slot series of cutters: https://www.iscar.com/products.aspx/countryid/1/productid/3723
These are the random inserts I have.
That makes sense. I sort of remember it now. I thought they come off ebay.A long time back I linked a couple of listings 16ER and 16IR mixed packets of 1.0, 1.25, 1.5, 1.75 and 2mm pitch, two of each and the seller reboxed them like that. I remember you may have bought them too? then I think the first insert is one of those. Looks like the ones I use anyway. Should have etching on the side or bottom with the pitch and 16IR.
Nothing wrong with them, tho 16IR will only fit in larger bores. SNR0016M16 is one of the suitable holder codes.
So perhaps I am learning something.A long time back I linked a couple of listings 16ER and 16IR mixed packets of 1.0, 1.25, 1.5, 1.75 and 2mm pitch, two of each and the seller reboxed them like that.

As well as the shape, another way to sort/categorise them is if they are single or double-sided. Double-sided ones are generally negative rake and need a reasonable machine to use them. Double-sided ones will have a parallel through hole; single-sided generally a countersunk hole
Yes I have the tools for most of those.Top, middle are parting inserts. If they are very wide, they take a good bit of power to drive them and can be wasteful of material (parting off a 2mm washer with a 4mm tool, you waste twice what you are making). For home gamer stuff, 2mm is good, 3mm for deeper cuts.
lolMiddle, adjacent the bearing look to be most useful of the lot.
Kram has jogged my memory as to what those are.The triangular ones to the right are a mixed grill. The ones with large corner radius again take more power to drive than sharper ones.
Bottom middle (to the right of the huge diamond), rectangular shape is similar to what should be in the box of your original first photo.
I already loads of tools. I also have packets of tips . Those were just random ones.Mmmm put them all back in the drawer/ box what ever. Buy a set off tools suitable for your purpose. Then you will know what inserts they require. Then build your tool collection from there.
The faster is was spinning the easier/more it slowed down.
Possibly .but I wouldn't know how. I do have a clamp meter but it might take a few months to find it.There is a horsepower calculator here:
Turning Horsepower Calculator
Calculates the horsepower and material removal rate for a turning operation.www.custompartnet.com
It might give you some rough number concerning what your cut is demanding. If it is close to the available input power, then that might just be life. If it is way lower than the input power, then it might point to a problem.
Can you measure the amps the phase converter or whatever is drawing from the wall? Can you measure the amps the machine is pulling?
With my little bit of lathe experience I get the impression that taking heavy cuts in softer steels like S235 and S275 is a bit like walking through mud. It zaps more power then the harder stuff like EN19.Resurrecting an old thread as I am sorted tools and tips again.
Sadly Ronan is no longer with us as I am sure he would have known But whilst turning some S275 yesterday I found the lathe motor bogged down with just a 2mm cut on.
The faster is was spinning the easier/more it slowed down.
Anyone know if there is an adjustment that might help?
