Model and Technical Parameters

1. Model: DJGZ-III

2. Charger Input Voltage: AC (100V~240V) ±10%, 50Hz/60Hz

3. Rotation Speed: 0–1200 rpm ±10%

4. Rated Torque: >8.5 N·m

5. Temperature Rise of Main Unit: ≤25°C (surface temperature not exceeding 50°C)

6. Noise Level: ≤75 dB

7. Maximum Output Power: ≥400 W

8. Battery: 12V lithium battery, 2500 mAh

9. Equipped with a brushless motor and lithium battery, the device features compact size, high torque and extended service life. The lithium battery is lightweight with large capacity, supporting up to 3 hours of continuous no-load discharge to fully accommodate various complex surgical procedures.

10. It is the first domestic bone drill adopting an integrated design of control system and battery, different from conventional devices with non-removable built-in control systems. This design enables the control system to be detached together with the battery for high-temperature and high-pressure sterilization, preventing damage to core electronic components during sterilization and greatly prolonging the equipment service life.

11. The integrated control system and battery can be easily disassembled. If the control system malfunctions, only the control module needs to be replaced for after-sales maintenance instead of shipping the entire device back to the factory for disassembly and repair. This eliminates overseas transportation difficulties, cuts delivery time and logistics costs, and significantly optimizes after-sales service efficiency.

Features of Bone Drill

The drill delivers an optimal balance between rotation speed and torque for smooth drilling operations, shortening surgical duration. The spindle and drill chuck are tightly fitted without welding, drastically improving concentricity with axial runout less than 0.003 mm. It supports long continuous single-cycle operation to prevent surgical interruptions.
