Length: 21mm, 25mm
Packing: 6 boxes
Style: K frustration
1. The cross-section of K-file is diamond-shaped, the rotary cutting effect is weak, the thread pitch is tight, and the cross-sectional area is large, which is mainly used to remove the root canal wall dentin and dredge root canal.
2. The cross-section is circular, and the cutting edge is almost perpendicular to the instrument. When working up and down, the working efficiency is high, and it is not suitable for rotary cutting. Otherwise, it is easy to break. When the root canal is thicker and there are more cases of debris in the lumen, it should be used for eugenics.
3. The cross-section of the enlarged needle is triangular, which is used for root canal rotation to cut dentin.
4, S needle (spreader) for the lateral pressure of the root canal filler, the working part is a smooth tapered cylinder, the tip of the needle is round, or A certain angle.
5, P needle (Plugger) for the vertical tube pressure of the root canal filling, smooth tapered cylindrical, needle tip straight.
