Just one more reson to not to buy China made tools . I do a little scraping on rainy days , Tear things apart and put the copper , alum. etc. in barrels and sell once a yr. or so . Several yrs. ago We was at a flea market and my cousin picked up a 4 1/2 in. angle grinder . The guy had a stack of`em for 10 bucks so I thought I`d grab one to . Well as they say ya get what ya pay for , it lasted about a hr. The other day I found it and went to tearin it apart and when I cut the cord at the tool end I noticed it only had two wires inside , very thin wires . So I dicected the three prong plug and the ground prong was`nt hooked up to anything , It was just glued on there for show !! Dont know why or how they can get by with that kind of stuff .
