The F19GK1-SPQ6 is designed for everyday rotary cutting in general dental surgery. Typical work includes opening and shaping cavities, preparing teeth for crowns and removing old restorations. Each task puts the bur at the centre of the operator's field of view; glass optical fibre lights that field, and the three-way spray keeps cooling water around the bur as it cuts.
General dental practice is the natural home for a standard push head. Restorative treatment rooms run handpieces of this pattern through long preparation sessions, and hospital dental departments use them in the same way. The dentist operates the handpiece and changes burs at the push-button chuck between preparation stages. Units fitted with KaVo-pattern connections take the SQ-A3 coupling directly.
The 135 °C sterilisation rating suits the routine of a busy surgery, where a handpiece goes through reprocessing between appointments and returns to the chair. The glass optical fibre is made to hold its light output through those cycles, so the working field is lit for the last appointment of the day as it was for the first.
The turbine needs two supplies at the chair: air at 0.25 to 0.27 MPa to drive the rotor, and water to feed the three-way spray. A sound level of up to 70 dB is part of the same working picture, with the balanced rotor turning at speeds above 300,000 rpm. These figures describe a handpiece for general surgery. The quick coupling lets you remove the handpiece from the hose for reprocessing and return it for the next patient.
