Royva Torque Head LED Handpiece Economic Model

For cartridges and bearings
Each cartridge adopts German dynamic balance testing technology to ensure concentricity above the micron level; Benefiting from the new clamping structure design, the runout rate of the pressed arbor is lower than 0.01mm, and the runout rate of the burs is greatly reduced, making it more stable when working, without swinging burs.
Ceramic bearings imported from Germany are used in its interior, the cartridge vibration is extremely low. It works with Good balance, Smooth running, Silent and More stable. High load capacity and good heat resistance, longer service life.
In addition, the open design for cartridge can be deeply cleaned to prevent bacterial residue, easy to maintain and extend the service life.
 For latch type: Push button chuck
Stainless steel press back cover, acid-resistant and corrosion-resistant. The back cover matches the cartridge in all directions, with moderate rebound strength of the push button and better hand feeling.
Introduced innovative KV shaft, the number of presses can reach hundreds of thousands of times, the maximum clamping force of the press shaft can reach more than 4.5kg, the clamping force is better than the industry standard, safe burs removal to prevent ‘flying burs’. Adopt push button chuck type, convenient for dentists to change the burs quickly, firm burs loading, quick burs pickup.
For Water Spray type
Upgrade the large water spray hole, water spray smooth, not easy to block. Four point water spray design, spray water directly to the tip of the surgical burs, fully cooling the cutting parts, effective protection of the burs and the tooth.
About the noise
Refined dynamic balancing process equipped with ceramic bearings, when the cartridge work，the burs keep stable. Working with strong power and low noise. The decibel level is lower than 60, and the cutting efficiency is high to reduce the patient’s pain and relieve the tension.
For the body
The body can be disinfected repeatedly at 135 degrees high temperature and pressure, which will not cause external deformation of the cartridge and bearing damage.
Handle craftsmanship is exquisite; precision curved body, fitting the human body mechanics design, science to improve the comfort of grip, stable and non-slip, wear-resistant and anti-drop.
How to use
Before use:
1. A clean, dry, oil-free air compressor with an air pressure between 2.3-2.8kgf/cm is required.
2. Install the burs to the designated position of the high-speed handpiece and press the switch.
3. Press down the pedal and check the dental handpiece operation and the head spray for normal operation. Note: Empty the pedal for 15-30 seconds to have reached the normal circulation of the water and air tube. If everything is normal, then you can start using the dental handpiece.
In use:
Turn the bearing by pressure to achieve high speed rotation of the burs and use the correct technique to cut the tooth body.
After use:
Sterilize the handpiece by autoclaving according to the correct process.
