Waldent Professional H-File 21mm #15 is a stainless steel hand endodontic instrument designed for effective cleaning and shaping of root canals during endodontic procedures. Crafted with a refined tear-drop cross section and sharp cutting flutes, it provides efficient dentin cutting and smooth tactile feedback inside the canal. The file is particularly useful for negotiating canals before rotary instrumentation and for controlled shaping in straight to moderately curved canals. Its non-cutting pilot tip helps reduce the risk of canal transportation while improving safety during instrumentation. The ISO color-coded handle allows quick size identification and comfortable grip for precise manual control. Made from high-quality stainless steel alloy, the file offers excellent elasticity, tensile strength, and durability, making it suitable for multiple clinical cases. Fully autoclavable, it supports standard infection control protocols in dental practice.
