Shop Talk 19: Parting Tools

I'm often asked to talk about parting tools and the different types. This was my attempt at the discussion but I feel like I missed something. Perhaps this is a better subject for me during an actual job at hand.
There are two basic types of parting tool, high speed, and carbide, or carbide insert. Carbide inserts are great for production, and everyday use in the working shop. They have great chip formation and can run at higher speeds. However that can pose problems on smaller or less rigid lathes.
High speed steel would be my first pick, especially for home and hobby use. They can be easily re-sharpened and will last for years. You can have an assortment of blades each with a different grind on the end. They have less tool pressure and can run at low speeds.
One key point to remember, if your having chatter problems, often times reducing the RPM, and feeding in harder it will reduce or eliminate the chatter. Always make sure you have a good sharp tool, or a good insert that isn't burned up, and your tip is on center or just slightly above.
Hopefully my viewers will get something out of the video, and I'll be sure to touch on this subject as it arises later.
