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 axis of the instrument. They are 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 and a square cross-section, these files last up to 8-10 endodontic cases.
INDICATION :
For cleaning and shaping of canals.
Negotiating the canals with hand files prior to using rotary files.
It can be used as a pre-bent file in curved canals.
ADVANTAGES
Sharp and mirror-like finishing edge.
Its hard-fiber stainless steel prevents corrosion after repeated cleaning and sterilization.
Have less separation potential.
Have the potential to bypass obstruction with great ease.
Provide Smooth Tactile Feel during 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, 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.
K file is the strongest of the hand file.

Watch Winding Technique
The use of the file in a forward and backward 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.
