I don't know what to make of Drill Hog. I have their Letter set which seems top notch, and their Silver&Demming which are kind of rough. They're marketed as USA made but not marked as such and have very little internet presence short of eBay and a YouTube review. But hey, lifetime warranty is always cool. I also have Norseman in mechanics and stub length and you certainly can't go wrong with them if you can handle the cost.
