Waldent Professional KFile 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The K-file works on the "pull" stroke - that is, by scraping the canal walls as it is withdrawn from the canal. It is advanced to the full working length rotated 1/4 to 1/2 turn clockwise, and withdrawn while being pressed against one of the walls.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
