The G01-SP4 is designed for rotary work in general dental surgery: opening cavities, shaping teeth for crowns, and removing old restorations. A typical appointment moves through several burs, and the standard head, with its push-button chuck, is built around that sequence. A one-way spray keeps cooling water on the cut throughout. Cutting enamel and dentine at speed is the core task, and the cooled bur supports every stage.
Restorative treatment rooms and hospital dental departments run handpieces through repeated preparations in a session. In those settings, the practical questions are about supply: which air figure the unit must deliver, which cartridge code to hold, and which handpiece code to reorder. The specification answers each one directly. The air supply is 0.25 to 0.27 MPa, quoted for a four-hole connection, and the cartridge is H01CA-SP. Hospital departments often hold several units, so a common figure matters.
Dentists and dental assistants work with a sound level of 68 dB or less, which suits a treatment room where talk with the patient continues through the appointment. The rotor turns above 300,000 rpm, the speed range used for cutting enamel and dentine, and the dynamically balanced movement spreads its load across the shaft and its bearings.
The anti-suction, dust-proof structure keeps grinding dust away from the bearing, and the machine head is CNC-machined from a single piece. This practice standardises on this handpiece, with one set of codes and one supply figure for the whole instrument shelf. The result is a short, clear list for the practice manager.
