Kerr LightSpeed LSX rotary instruments feature a unique spade-blade design that cuts only where needed, thoroughly cleaning the apical third while preserving coronal and mid-root structure for biologically optimal root canal preparations. Each 21 mm size 70 file is nickel titanium with clearly marked length rings at 19, 22, 24, and 25 mm to help eliminate the rubber stop. Supplied in a 6-file package (LX21070 / 835-7021).
