carbide insert replacements

[Sam Fleisher]

Occasionally I will use a carbide tool. Lately mostly to turn some brass and copper ferrules on tool handles etc.. This has caused me to need some replacement bits.

Looking around I see there's a negative rake insert available in the size I use. Is this a thing I need or should I just stick to the regular ones? If I get some to play with are they used level like normal carbide or is there a different way to present to the work?

FWIW

I have one for my Rikon and I like it. It works good for me for that final pass to flatten the bottom of the bowl and the transition to the side wall. It also helps remove tool marks.

Do you use it just like any other carbide? 90 degrees from the tool rest or do you present it differently?

Yes, you don't use it any differently than a regular one. Try it and see if you like it.
