I have really had a good laugh at some of the guys braging on the Snap On,Mac,& Matco Tools. They ought look at where some of the air tools are made! Now as far as 4.5" grinders are concerned most guys use them in place of a 7" Disc Grinder and burn them up using them on heavy welds etc. Don't let the name China, Japan, Korea fool you as they make aome quality tools but most american companies will not import them and prefer to bring juck over to sell for a big profit. My 2 cents!
