This was a question from a customer that we answered recently. I thought it might be helpful to post it here. The Badeco is made in Switzerland. It is the premium hammer handpiece for jewelers and is used by the finest jewelers in the world for precision stonesetting. It is made for production use, meaning it can handle 8 hours a day of use. The Foredom H15 is basically a copy of the Badeco. The only parts that interchange are the screw in tips. It is a good hammer handpiece but lacks the stroke range (heavy to fine) of the Badeco. It is made in China for Foredom. If you are not a professional jeweler hammer setting stones for a living, and you never used a Badeco, you will be perfectly satisfied with the Foredom. The duplex spring versions of both do share the exact same duplex spring parts which are made in the USA. Duplex springs can break and are not covered by warranty. If used properly, they do give good service.
