Foredom Mandrel 2.35mm Left Hand

Description:

Mandrel 2.35mm left hand is a uniquely engineered dental rotary mandrel featuring a reverse-thread (left-hand) screw system designed to secure polishing wheels and abrasive discs that tighten counter-clockwise. This prevents loosening during operation on handpieces that rotate in the opposite direction of standard right-hand threading. This feature provides enhanced safety and stability, particularly in high-speed polishing applications. The mandrel�s 2.35mm shank is compatible with common micromotors, electric handpieces, and air-driven contra-angle systems used in both clinical and laboratory environments. Its left-hand screw interface offers secure mounting for accessories such as felt wheels, rubber polishers, abrasive discs, and specialty finishing tools used to refine composite restorations, adjust ceramic surfaces, smooth acrylic appliances, and polish metal components. Constructed from stainless or hardened steel, the mandrel withstands sterilization cycles and high rotational forces, ensuring durability in demanding workflows. Its balanced design minimizes vibrations that may lead to uneven material removal or surface irregularities, improving precision during detailed finishing tasks. This mandrel is especially beneficial in laboratory applications where technicians frequently use reverse-rotation lathes to shape prosthetic frameworks, wax patterns, and acrylic bases. Its reverse threading ensures wheels tighten naturally with the motor�s rotation, offering consistent security and performance. Whether used chairside for fine restorative adjustments or in a laboratory for bulk polishing, this mandrel provides reliable retention and smooth, controlled functionality.
