Description
Stainless Steel Hand K-Files
Waldent Professional K File is manufactured by twisting or grinding a square or triangular tapered shaft so that the cutting edges are almost perpendicular to the long access of the instrument. Designed with four cutting edges & a 60° tip with a 135° cutting angle with good cutting ability. This together with its tight spiral ensure a safe preparation. With a more refined cutting edge, a square cross-section, these files last up to 8-10 endodontic cases.

Features :-
- K file is the strongest of the hand files.
- Have less separation potential.
- Have potential to bypass obstruction with great ease.
- Provide Smooth Tactile Feel while instrumentation.
- Used with rasping, pulling motion, or watch winding motion.
- Tighter flutes, with more in number, when compared to the reamer.
- Handles are made up of medical grade plastic, which is ISO color-coded; numbered according to size.
- Blades are made of a special stainless steel alloy, which allows a high degree of elasticity & tensile strength.
- Inactive pilot tip.
- Pack of 6 Files.
- It is the instrument most commonly used for cleaning and shaping.
- The K-file works on the “pull” stroke – that is, by scraping the canal walls as it is withdrawn from the canal. It is advanced to the full working length rotated 1/4 to 1/2 turn clockwise, and withdrawn while being pressed against one of the walls.
TECHNIQUES FOR USE:
Watch Winding Technique:
- The use of the file in a forward and backwards motion, as if watch winding, with slight apical pressure. This allows the file to effectively debride the canal dentine by moving slowly down the canal.
- For K-type files, once the file has reached the desired working length a push and pulling action is used around the circumference of the canal, while only maintaining contact with the canal wall on the outstroke to minimize a debris blockage apically
