The dental electric handpiece is an optical fiber handpiece driven by electricity. The electric motor can be paired with a 1:5 speed increaser, which can increase the speed up to 5 times. The maximum torque is 3.5N/cm, which ensures a quick, precise treatment, as well as the easy replacement of high speed handpieces. It also protects the water spraying holes from being blocked by small particles, thus ensuring outstanding cooling effects. The end of the handpiece is detachable, making cleaning easy.
