Description:
The AYD-WM4 low-speed handpiece with external water spray can be connected with a polishing brush, dental polishing ring, grinding head, and root canal reamer.
1.The AYD-WM4 low-speed handpiece adopts external water spray, so it can provide the solution for the problem of no water output caused by pipe blocking. It is equipped with stainless steel snap joints with superior flexibility, thus ensuring that the water pipe will not be loose or drop from the joints during the application of the handpiece.
2.The motor will stop running or be stuck because of lacking oiling. Without the lubricating oil, the blades which lead to motor rotation will be not resistant to friction, thus generating dust. While the abrasive resistance of the AYD-WM4 handpiece is 50% higher than that of the others. This can directly improve the performance of the motor.
3.The jitter frequency of the handpiece is quite small. The testing results show that the radial run-out is less than 0.03mm which is more suitable for various fine operations. This handpiece can be more convenient.
4.The dental polishing ring is made of material from America which is treated by many steps of the process. It will not be damaged after disinfection with maximally 134-degree high temperature and high-pressure steam.
5.This dental drill adopts ceramic bearing, a cage that is made of material from the UK. The two sides of the bearing are equipped with a sealing device that can protect the internal of the bearing from external dust and some other impurities. The inner and outer ring of the bearing after many times of circular grinding treatment can ensure its concentricity, greatly improve the dynamic performance of the bearing and prolong the service life of the bearing.
