CUSTOMER REVIEW



These are made in U.S.A., so much better quality than Chinese crap sold by DeWalt, Bosch and Milwaukee these days. If used correctly these should last a while (using oil/paste and correct techniques). Having said that, I once went through the whole set in less than a week due to not using cutting oil and not having proper tapping wrenches (my department was just starting out). After acquiring a new set I made sure to do things right this time and the set is still with me.

If you are only looking for a few particular sizes - I suggest taking a look at Guhring. Those are German made, they blow these out of the water, but are priced accordingly.
