H Files are manufactured by machining a spiral groove into a tapered round stainless steel or Nickel-Titanium (NiTi) wire. This process creates a series of very sharp, cone-shaped edges that stack upon one another. Because of this unique geometry, H Files are exceptionally aggressive when used in a longitudinal "push-pull" motion, making them the preferred choice for widening a canal after a glide path has been established or for retrieving debris and filling materials.

Features
High Cutting Efficiency: The stacked-cone design provides superior cutting ability compared to twisted files, especially during the withdrawal stroke.
Tapered Spiral Flutes: Features deep, sharp flutes that are optimized to lift dentin shavings, necrotic tissue, and old filling materials coronally.
Circular Cross-Section: Provides a specific geometry that focuses cutting energy on the canal walls during the pulling motion.
Superior Debris Evacuation: The wide spaces between the machined flutes allow for significant debris accumulation, reducing the risk of apical blockage.
Precision Stainless Steel: Constructed from high-grade stainless steel to ensure a sharp, long-lasting edge and adequate lateral stiffness.
