Key Features and Specifications

Enhanced High-Torque Performance
The A2 Pro is engineered for high-efficiency performance, delivering powerful, non-stalling torque even under heavy load. This enables fast and decisive removal of tooth structure and old restorative materials, optimizing the preparation process and significantly reducing overall chair time.

Superior Bearing System
The handpiece is equipped with high-precision German or Japanese ceramic bearings. Ceramic bearings are preferred due to their exceptional durability, low friction, reduced vibration, and superior heat resistance. These advantages result in quieter operation and a longer lifespan compared to traditional steel bearings.

Ergonomics and Design
The handpiece features a streamlined, anti-slip body design, often finished in chrome or a matte coating. This ergonomic form fits comfortably in the clinician’s hand and minimizes fatigue during prolonged procedures.

Efficient Quadruple Water Spray
An advanced quadruple (four-port) water spray system ensures uniform and thorough cooling of both the bur and tooth structure from multiple angles. This is critical for preventing thermal damage to the dental pulp during high-speed cutting.

Secure Push-Button Chuck
The handpiece includes a dependable push-button chuck mechanism that allows for quick and secure bur placement. This ensures excellent concentricity and prevents bur loosening or accidental release during operation.

Sterilization Capability
The A2 Pro is fully autoclavable, typically up to 135°C, ensuring full compliance with strict infection control and sterilization protocols.

Connectivity
The handpiece generally features a standardized four-hole (Borden) or two-hole (Midwest) connection, or a quick-disconnect coupling. This allows seamless integration with most existing dental unit systems.
