In combination with an apex locator, the compact Endo 6 : 1 contra-angle handpiece facilitates locating the apex without the need for a file clamp. Depth is measured directly via the contra-angle handpiece. The extremely compact head ensures that the dentist has the best possible view of the root canal, and the slim design without a file contact clip is the key to perfect ergonomics. Thanks to the practical ISO interface, the user has a free choice of micromotors.
