Positive rake angle provides the active cutting action of the K3. Wide radial land provides blade support while adding peripheral strength to resist torsional and rotary stresses. The third radial land stabilizes and keeps the instrument centered in the canal and minimizes “over engagement.” Radial land relief reduces friction on the canal wall.

SybronEndo K3/dental k files:
Positive Rake Angle An instrument’s cutting efficiency is dependant upon the overall rake angle of the instrument’s cutting blades. Rake angles are determined by drawing a centerline parallel to the center of the file and determining the angle relative to the centerline. It can also be measured relative the circumference as indicated by the green lines on the examples below.
The Profile and most other conventional instruments utilize negative rake angles, which result in a scraping rather than a cutting action. As dentin is dense and somewhat resilient, cutting or chip dislodgment with negative rake angles is difficult and very inefficient.
