The \u003cstrong\u003eBadeco 437 Quick Change Handpiece\u003c\/strong\u003e (Part #134.747) is a precision twist-turn handpiece for flex shafts with 3\/32\" diameter shafts. Otto Frei first imported it from Badeco of Switzerland more than 30 years ago, and it has long been regarded as one of the most rugged and finely built quick change handpieces available for professional bench use. Under a renewed agreement with Badeco of Switzerland as their main North American distributor, the 437 is again available in the United States and to anyone who needs USA standard key tip quick-disconnect connections.\u003c\/p\u003e\u003cp\u003eThe 437 uses a fixed 3\/32\" collet that opens and closes with a simple two-handed twist of the handpiece body, with no key required. Fit, finish, and tolerances are characteristic of Swiss manufacturing, with every component assembling to the precision of a fine mechanical timepiece.\u003c\/p\u003e\u003cp\u003eThis model includes a USA-made duplex spring attachment so it connects to standard Foredom-style flex shaft machines.
