I am happy to buy tooling from other countries, such as Israel, Germany, England, Japan, etc. I will not buy inserts made in China.
Refer to the forum below where fellow machinists note differing quality between Kennametal inserts made here and China. This is from 2012. From then until now, Kennametal has built additional factories (perhaps sweatshops, idk) in China.
Kennametal making inserts in CHINA now
A lot has changed since 2012, a lot of what was once made in the US in 2012 is now made abroad.
You might like your made in the US endmills inserts etc, but the raw material and blanks likely come from China. CarbideBob could put better than an educated guess as to Chinese content.
