3/8” boring head bar set that uses carbide inserts?

The ones from MariTool are also attractively priced.

And made in the USA. The Haas are from mainland China, but under local Haas direct management. I have both bar brands in steel and carbide and they are excellent. Not Iscar level, but far better than anything I’ve seen/tested from mainland China and available from PM, Shars, Alibaba, eBay, etc.
