Kerr Endodontics K3 NiTi Rotary Files
K3 is a third generation asymmetric endodontic file system. Designed to remove debris quickly, efficiently and safely, K3 addresses technical and procedural issues like no other ground-fluted file.

Variable pitch
Many files maintain a constant pitch (distance between the cutting edges) throughout the length of the file. This may result in a “screw-in” effect. The K3 file has a varied pitch that effectively transports debris coronally. This is important not only during initial cleaning and preparation but also for revisions.

Less friction, more stability
Alleviating pressure on the cutting edge of the radial surface of K3 files minimises frictional resistance. Other NiTi systems have wide radial lands that increase friction and can lead to breakage.
K3 files have added mass to the cutting surface to provide greater support to prevent deformation. With other systems, blade rollover or cracks can occur during instrumentation.
