Key Features

S-Blue

Four-file rotary sequence (B0 starter, B1, B2, B3) with circular triangle cross-section, uniform 425–500 rpm / 2.5 N·cm settings, and pre-bendable heat-activated NiTi (per brochure Design Concept and Specification table; brochure body says only "heat-activated material" — "Blue" is inferred from the product name)
