Jinme J4 Mini head - 4 hole connection


The Jinme J4 Mini Head Handpiece (4-hole connection), model J4-MUQ, is a high-speed turbine handpiece purpose-built for pediatric dentistry. Its head measures just 8.9mm, roughly half the size of a standard adult handpiece head, improving visibility and access in smaller mouths. It operates at 380,000–480,000 RPM, drawing 14W of power, with noise held to 65dB or below and a water flow of 90–110 mL/min for cooling. Required working air pressure is 0.2–0.3 MPa. High-precision bearings sourced from Germany are used to support smoother, quieter operation. Bur changes use a push-button mechanism, and the handpiece is designed to pair with short-handle burs sized for pediatric use. An anti-suction design is included to help reduce backflow of oral fluids into the handpiece between patients, and an NSK-style quick connector is included with purchase.

Description

The J4-MUQ high speed dental handpiece is small, making it suitable for child treatment.

Every dentist deserves to have a piece of mini head dental hand-piece for children.

Features of dental handpiece

1. The handpiece head is small, making operation flexible.
The J4-MUQ handpiece uses a super small head of 8.9 mm, which is half the size of a standard head available on the market today. This allows the handpiece to have easier access to the back teeth without the limitations of a narrow space.

 

2. German engineered bearings
The J4-MUQ uses high-precision bearings imported from Germany. The bearings are designed with special angles and they can generate a centripetal thrust force to make handpiece operation more stable and quiet, as well as contribute to a greater torque.

 

3. It’s equipped with short handle bur specially used for children’s teeth.
Because children’s mouths are smaller, it is often more difficult for dentists to do their work. Because the J4-MUQ dental handpiece is equipped with a short handle bur specifically designed for children’s teeth, as well as a small head, operation is more flexible and easy during treatment.

4. Anti-suction system
The use of anti-suction system can prevent the suction of blood, virus and skin particles caused by the negative pressure produced when handpiece stops operating, thus preventing any risk of cross infection. This also better protects the dental cartridge against damage caused by foreign materials, largely improving the service life of the handpiece.

 

5. It’s designed with a NSK quick connector. (Free with purchase)
