Core Product Advantages

Large Torque Head + 4-Way Full Surround Water Spray

The wide torque head generates stronger cutting force for large-area tooth grinding. Four evenly distributed water outlets fully wrap the bur, rapidly dissipate cutting heat, avoid pulp overheating and ease patient discomfort during heavy trimming work.

High Bright Shadow-Free Integrated Fiber Optic LED Illumination

Built-in high-efficiency light guide fiber delivers natural shadowless bright light. Tiny deep cavities and molar margin details can be clearly displayed to support precise restorative treatment.

Push Button Quick Bur Chuck Mechanism

Tool-free one-click bur loading and unloading. Stable clamping force supports dental burs up to 27mm long. No bur shaking or falling off under high-speed rotation, convenient for frequent bur replacement.

Premium Silent Ceramic Ball Bearing Cartridge

Precision ceramic rotor ensures stable maximum rotation speed at 360,000 RPM. Ultra-low vibration and noise ≤60dB(A), effectively relieving wrist fatigue during full-day clinical work.

Ultra-Lightweight Anti-Slip Stainless Steel Body

Integral medical stainless steel shell with anti-slip texture. Total weight less than 42g, wear and corrosion resistant. Supports repeated 135℃ high-temperature autoclave sterilization.

Universal KV Quick Coupler Compatibility

Three optional connectors: 2-hole / 4-hole / 6-hole KV fiber optic coupler. Stable air and light transmission, fully compatible with mainstream dental chair units and automatic handpiece cleaning & lubrication equipment without damaging internal turbine components.
