• The machine head of the 16:1 variable speed dental endodontic handpiece is chromium and copper plated so that it is not easy to be corroded.
• Bur changing method: push type bur changing (D type clamp).
• Dental cartridge: the collet type dental cartridge which is equipped with bearing with oil.
• Anti-reverse suction device: sealed anti-reverse suction device.
• Connection port: it can be matched with NSK, Dentsply, Denjoy and some other root canal motor with gear interface.
• Cleaning of the oiling device: the oiling device can be disassembled by screw joint.

1. The 16:1 variable speed dental endodontic handpiece adopts unique appearance design which meets the standard of ergonomics. It is equipped with comfortable handle which can effectively relieve hand fatigue caused by long time operation.

2. The mini integrated bur adopts exquisite machining craft. It is produced in one piece, thus the assembling gap can be reduced to ensure precision and firmness. Then the torsion of the handpiece can be indirectly improved while the noise and vibration can be reduced.

The whole bur has no welding spot, so there will be no possibility of water and air blocking caused by rust which can directly solve the problem of poor atomization etc.

3. High transmission efficiency: this dental drill adopts gear set which is made of superior material by high precision CNC machining craft. It can ensure low noise as well as high transmission efficiency which can be up to 45% which is market-leading.

4. The dental drill adopts detachable and easy cleaning machine head, modular assembling so the assemble and disassemble is convenient and quick. The operation is easy. Besides, the consequent maintenance can be carried out by yourself easily.

5. This drill adopts high precision bearing from Germany. The unique angle contact bearing structure can generate centripetal force during handpiece running so that the handpiece can be more stable, quiet and generate larger torsion during high speed running.

6. The 16:1 variable speed dental endodontic handpiece is equipped with internal cooling system which can realize uniform cooling and avoid water splashing. It can provide better atomizing effect.

7. The anti-reverse suction system can prevent that the reverse suction of dust, blood, virus and fragments into the bur caused by negative pressure when the handpiece stops running. The system can keep the bearing clean and protect the dental certridge and bearing of the handpiece from being damaged by foreign matter. This can greatly improve the service life of the handpiece. Meanwhile, it can prevent cross infection.
