Huiershun Professional 3.1mm Precision Mandrel Bit for Electric Nail Drills

Elevate your nail technician toolkit with the Huiershun Precision Mandrel, a fundamental component designed for both professional salon environments and high-end home manicure setups. This mandrel core is engineered specifically to serve as the perfect interface between your electric file and disposable sanding bands. By providing a stable, balanced foundation, it ensures that every stroke is smooth, controlled, and efficient, allowing you to achieve a flawless finish on natural, gel, or acrylic nails.

Key Benefits

High-Stability Precision:** True to its designation as a "PRECISION TOOL," this mandrel is manufactured to minimize wobble and vibration. Even at higher RPMs, it maintains a steady rotation, which is critical for preventing "jumping" on the nail surface and ensuring the comfort of the client.

Universal Compatibility:** The 3.1mm shaft diameter is designed to fit seamlessly into most standard professional electric nail drills (E-files) available on the US market, making it a versatile and essential replacement part for your existing equipment.

Enhanced Grip Design:** The barrel of the mandrel is optimized to hold sanding bands securely. This prevents the bands from slipping or flying off during intensive grinding, shaping, or callus removal, ensuring a safer and more continuous workflow.

Professional Durability:** Built from high-quality, corrosion-resistant materials, this mandrel is designed to withstand the rigors of a busy salon. It maintains its shape and performance through repeated use and standard cleaning cycles.
