Revolutionize your prep time with the S3 Easy-Off Mandrel Bit. Designed for high-volume nail technicians, this bit completely eliminates the daily struggle of removing tight or stuck sanding bands. Machined from premium Stainless Steel, it securely holds standard 6.5mm (1/4″) bands while maximizing your salon’s workflow efficiency.
The “Easy-Off” Split Technology: Unlike solid mandrels, the S3 features a highly engineered split-prong (deep slotted) structure. This hollowed design acts as a tension spring—compressing slightly so bands slide on effortlessly. Once the e-file reaches high RPMs, the centrifugal force expands the prongs to lock the band firmly in place.
Precision Edge (Flush Fit): The S3 features a Chamfered Flat Top. This allows the sanding band to sit completely flush with the metal edge, giving you the perfect 90-degree angle for detailed sidewall refinement without any protruding metal getting in the way.
Features
- Effortless Band Changes: The dynamic split-prong design saves time and saves your fingers. Never fight with a stuck sanding band again.
- Centrifugal Locking: The faster it spins, the tighter it grips. Ensures 100% stability and prevents “flying bands” during heavy-duty acrylic or gel removal.
- Chamfered Flat Top: Enables a perfect “flush fit” with sanding bands, providing unobstructed visibility and access for razor-sharp edge work.
- Universal 6.5mm Fit: Compatible with all standard 1/4″ (6.5mm) sanding bands. Built on a perfectly concentric 3/32″ shank for a smooth, vibration-free experience.
