Carbide or any inserts makes my head hurt trying to understand them. I'm not only overwhelmed with the information but also overcome by the price on most of them.
I usually use the cheap brazed on tools that I reshape & sharpen or HSS. I don't cut many threads without a tap & die set but those get pricy for one of jobs & sometimes I don't have time to get the correct one. I also hate to grind a inside threading tool. & lastly I'm cheap.
After just having to cut a inside thread I was looking at eBay & found these:

What can you tell me about these? Looks like I get a cutting edge for about a buck a piece with these so it seems worth while.
