Description
YING-SU high speed dental handpiece uses a standard head and open general-purpose dental cartridge, with a torque up to 0.35~0.4N. It uses push-button bur changing mode and three point water spraying. Two-hole and four-hole types can be chosen according to user's requirements. It is also designed with power generation function.

Technical parameters
Working air pressure: 0.22(MPa) ~0.25 (MPa)
Rotational speed: 350(krpm) ~400(krpm)
Torque: 0.35(N) ~0.4 (N)
Water flowrate: 90(min/ml) ~110(min/ml)
Working water pressure: 0.2(MPa) ~0.23 (MPa)
Spraying pressure: 0.3(MPa) ~0.35 (MPa)
Noise: ≤60dB

• It uses an integrated handpiece head that is produced one-time, decreasing the gap produced by assembly, which can ensure the precision and firmness. This can also increase the torque of handpiece indirectly, lower noise and reduce vibration. There is no solder joint on the head, therefore, water and air blocking caused by rust can be prevented and bad water spray problem can be decreased.
• A push-button bur changing mode is used to replace the gripping type mode, which makes bur mounting and detaching quicker and more convenient, saving time for the users.
• YING-SU dental handpiece is equipped with open cartridge, which can be in common use with NSK PANA MAX handpiece. This makes the handpiece repairing and spare parts replacing more convenient.
• The YING-SU dental handpiece dental handpiece uses JINME's independently researched and developed auto-chuck push button spindle. A precise miniature spring is equipped inside the spindle and with the high speed rotating of handpiece, it exerts a pre-tightening force on the chuck to ensure the bur is tight and secure to the handpiece. (Patent number: CN203263556U)
• Users can choose 2-hole or 4-hole handpieces according to personal using habit or based on the joint types, thus offering more versatile options. The YING-SU dental handpiece can meet the requirements for connecting with other handpiece pipes on different dental comprehensive treatment machines.
• YING-SU dental handpiece has independent three-point spray cooling system. The formed tornado type water spray surrounds the bur during high speed cutting operation to fully clean it and better cool it.
