Who makes them? At HD, all are chinese except Ridgid which claims to be packaged in the USA of domestic and foreign components... To me that means that the bits are made in China, cryo treated somewhere between there and here, then put into plastic packages here. I really dont want to buy Chinese stuff. And, the Ridgid bits didnt seem to hold their edge as well, though they claim to be fast cutting (in metal, no less, which was what I was drilling), compared to my black and gold colored bits. And I want to just be able to buy one or two sizes as needed. Are McMaster bits US made? It seems that their tools generally are. Thanks!
