The difference between h file and k file

Look at the logo on the back of the handle 1. The h gear is round: (1) The h gear looks like a mouse’s tail.

Some people call it a rat tail file, which has strong cutting ability, so it is generally used for lifting up and down.

(2) How to use: Pull up and down to cut, try not to rotate.

(3) Precautions for use: Because the blade is sharp, do not pull continuously in one direction, as it is easy to over-cut.

Be as gentle as possible when spinning.

When encountering resistance, do not pull violently, and try not to use it on root canals with large curvatures.

2. K file square: (1) Used to open extremely small and curved root canals.

(2) Triangular cross-section, better elasticity than traditional K-type (3) No cutting tip, no transition angle, avoiding shoulder bends and root canal perforation.

(4) With yellow stop block (5) Stainless steel, 6 sizes (015-040) 3. C gear pioneer: (1) Special alloy treatment process, effectively solves the defect of insufficient rigidity of the small gear tip.

(2) The tip 3mm has a higher hardness, several times higher than the same file, and can easily clear calcified root canals.

(3) The back of the file has good flexibility and can smoothly descend along the root canal wall.

(4) It is divided into five models: No. 6, No. 8, No. 10, No. 12, and No. 15. The two lengths are 21 and 25mm respectively.

Suitable for all root canals to establish straight canals.

There are also mixed sizes 6, 8 and 10.

(5) The pioneer file is a powerful tool for root canal treatment and has excellent toughness.
