Precision-Crafted EVA-ECS 1:1 Direct Drive Contra Angle Handpiece for Orthodontic Excellence

Ultra-smooth 1:1 direct drive mechanism ensures unmatched torque consistency, eliminating friction heat for prolonged procedures. Aerospace-grade stainless steel gears paired with ceramic bearings deliver 40,000 RPM noise-free operation.

Ergonomic 45° contra-angle head provides 360° access to posterior teeth, ideal for bracket placement, resin removal, and fine polishing. Autoclavable fiber-reinforced polymer body withstands 135°C sterilization cycles without warping.

Patented quick-release chuck accepts all standard ortho burs up to 2.35mm shank diameter. Integrated LED-ready port for optional shadow-free illumination during precision work.

Dual ceramic water-resistant bearings prevent corrosion from coolant exposure. Weight-balanced design reduces operator fatigue during 8-hour clinical shifts.

Engineered for orthodontists performing detailed debonding, interproximal reduction, and adhesive cleanup. Compatible with major slow-speed dental units including Bien-Air, Kavo, and W&H systems.

Packed with German-made tungsten carbide gears, this handpiece outperforms OEM models at 1/3 the cost. Bulk orders receive factory-direct calibrated torque test reports.
