Is there a way to make the stub be on the material that still in the chuck and not have the stub on the part that you've just parted off?
Regardless of any changes I make in my parting off tool, the stub is always on the parted off piece.

I have an angle on my HSS tool so it’s fractionally longer on the tailstock side. Always leaves the nub on the chuck piece.

Thanks, I'm using an insert.Quote:

You might be able to get inserts with an angle, I know we have them at work, just depends what style your holder takes.Quote:

Then the blade will shave it off. It seems that people set their parting blade a fraction low, though I don't advocate setting it high as some do.
EDIT: I use a HSS blade.
me too. I just live with the pip. I’ve read that grinding a bevel can cause the blade to deflect. Haven’t tested that theory though.Quote:

I have bought from my usual aliexpress tooling supplier straight and RH 3mm parting inserts, they also list a LH parting insert.
Hi Chris, Guys,
Yes it can ! Thin, in my case 2 mm thick HSS blades and deep cuts. Basically too much stick out. Also if the blade is not dead square to the work you will get run off even with a square end on the blade. If the blade is slightly canted it will run off as well.Quote:

Hi Neevo,
Since getting a bandsaw I tend to use it to cut anything larger than 32 mm diameter rather than parting off.Quote:

It’s annoying to have to part something off because it’s too big to put in the lathe. That’s where I feel a bandsaw will make all the difference.
