CARBIDE TOOLING???

[riversidedan]

Sorry I am not doing a better job helping here. Your red carbide tools from your original pic are just like the blue one in my pic only smaller. They will need to be ground before first use. Just like a new chunk of HSS you have to grind it before first use. Yours look like they have some angle not totally flush and yes you will remove some of the red and blend the Carbide tool into other Metal when grinding. Essentially you are grinding it just like a HSS tool. Think of it as all one piece but unlike HSS when the carbide portion is all ground up the rest you just throw away. HSS you can use to the very end.

Edit added link - if you jump to 40:00 minute point in this video you can see me grinding the blue tool from my earlier pic. Maybe that will help more than my pic.

couldnt really see a closeup of the tip but looked like the carbide was either flush or hung over the shank a bit...

Moving along, the more I Iearn about these carbide tools the more am liking indexable and insert tools for thier simplicity atleast for now but thanx for the input.

Here are some pics of several of them ground for various things. Radius, turning and threading. Indexible are easier for sure and when using a DRO they are repeatable in set up when you turn them as opposed to every time you sharpen these you have to reset. Inserts are also great for roughing. That said, you can often get better finish especially on light cuts with braised carbide. And you can customize them for things like a large radius. As you can see in these pics the first sharpen you likely end up with some overhang, just depends on the angle you want. The more you sharpen or in the case of the radius tools there is no overhang just angle up to the carbide cutting edge.
