Rotary NiTi instruments ideal for shaping root canals. Features: - High cutting efficiency even in the presence of complex root geometries: designed with a triangular cross-section and heat treated. - Minimally invasive: maximum thread diameter of 1 mm and blunt non-cutting tip. - Exceptional strength: resistant to torsion and cyclic fatigue. Minimal risk of breakage. - Excellent flexibility: heat treated to allow the instrument to be curved up to 90°. - Length: 19 mm. - Diameter: 3.5%. - Size: #19.
