Size 40
24mm
When canal morphology requires a mid-range instrument, the NES-1452 steps in. This ISO Size 40 tool measures 24 mm in working length and is engineered for controlled negotiation and condensation within root canals of moderate diameter. The standardized ISO sizing ensures predictable progression from smaller instruments and seamless integration with matching gutta-percha points or accessory cones.
Forged from surgical-grade stainless steel, the instrument maintains its shape and surface integrity through repeated sterilization cycles. The handle is designed for a secure finger grasp, transmitting subtle resistance feedback so the clinician can sense canal walls and avoid ledging. Its 24 mm length provides adequate reach for the majority of anterior and premolar cases while remaining manageable in restricted openings.
This size frequently serves as a transitional instrument during cleaning, shaping, or obturation sequences. Next Edge Surgical LLC supplies the NES-1452 as a precise diagnostic instrument that also supports therapeutic endodontic procedures—helping assess canal dimensions while facilitating effective material placement. A dependable mid-range option for everyday root-canal therapy.
