The Kerr LightSpeed LSX NiTi rotary endodontic instrument is designed to create biologically optimal root canal preparations. Its unique spade-blade cutting action removes dentin only where needed, thoroughly cleaning the apical third while preserving coronal and mid-root structure that tapered instruments may unnecessarily remove. Each file is 31 mm long, size 40, color-coded brown, and supplied 6 per package (LX31040 / 835-4031).
