Sharp edged, H-Files are used for probing, liberalization or extraction of debris. Made of stainless steel or NiTi, these files can only be used in traction because of their profile. H files, with either a cutting tip (Mani H files) or safe-ended hand files (Mani SEC-O H) are both used to grasp canal obstructions (often gutta percha but possibly separated files and/or carriers) and deliver them carnally through application of an upward force. Clinically, to deliver this upward force, the clinician must first bypass the obstruction with a K file (or its equivalent — possibly a “stiff” Mani D Finder). Once bypassed, the H file is inserted beyond the obstruction, and the aforementioned upward force is delivered using the engaged flutes of the H file. Consequently, their use is essentially for widening after passage of the K-File of the same number and for evacuating debris and organic tissue.
* The flute depth increases with the taper, creating a sharper, more flexible instrument
* With round cross section
* Made of NiTi alloy or Stainless Steel* 6 files per box, available of single or assorted size
