My son is an electrician and I have read that LENOX is a good brand name for tools, so thought he could try this set.  It comes in a very nice case and does have good quality tools inside.  It is very heavy, very little plastic parts in this set.  It comes with 10 pieces including hole saws for 7/8", 1-1/8", 1-3/8", 1-3/4", 2", 2-1/2".  The thing I like the most about this set is that it is made in the USA!
