Foredom H.20D Duplex Version 3/32" Quick Change Handpiece

The Foredom H.20D duplex version quick change handpiece is great for making quick bur changes without having to use a key. They are meant to be used with only one diameter size tool, in this and most cases, bits and burs or tools having a 3/32" diameter shaft. This Foredom H.20D quick change handpiece is based on an Italian lever style quick change handpiece, and is also very similar to the Swiss made Technique quick change handpiece. The Foredom H.20D version has the built in duplex spring for added flexibility. Please note that duplex springs have no warranty. Before choosing the duplex spring model please read the following: Duplex springs, and all parts related to the USA made duplex spring connections, have no warranty. Duplex springs should not be bent beyond 45 degrees during use! Duplex springs can be damaged easily if operated beyond the 45 degree angle or during detaching the handpiece from the end of the flex shaft. Duplex springs can also fail during normal use. If you choose a duplex spring model, you may want to purchase additional inner duplex springs (Single piece part number 134.279 Foredom HP76-Pack of 12 part number 134.280 Foredom HP76B) and learn how to change out and replace the inner duplex spring, the most common part that can fail.
