Product Overview
WISEGENT BR‑164AS‑E LED High‑Speed Dental Handpiece
WISEGENT BR‑164AS‑E is a fiber‑optic high‑speed dental handpiece designed for routine restorative dentistry, cavity preparation, crown and bridge work, and general tooth trimming. Equipped with premium ceramic bearings, it delivers a stable operating speed of 280,000–350,000 rpm under 0.22–0.30 MPa working air pressure, with noise controlled at ≤60 dB for a quiet clinical environment.
The integrated LED light provides ≥2500 Lux brightness, delivering 100 % shadowless illumination across the operating field for precise and comfortable treatment. Its 5‑water‑spray cooling system evenly distributes water around the bur, effectively cooling both the bur and dental tissue to prevent thermal damage and wash away cutting debris.
Featuring a push‑button chuck mechanism, the handpiece accepts standard burs of Φ1.595–Φ1.60 mm and allows quick, one‑touch bur changes. It is available in three head sizes — Small, Middle and Big — to match different clinical access and torque requirements. The ergonomic anti‑slip grip ensures steady handling and reduces operator fatigue during extended procedures.
Fully autoclavable at 135 °C and compatible with standard 4‑hole dental chair connections, the BR‑164AS‑E combines reliable performance, versatile configuration options and excellent cost‑effectiveness, making it a practical choice for dental clinics and hospitals worldwide.
Product Introduction
Detailed Product Description
1. Ceramic Bearing Rotor System
At the heart of the BR‑164AS‑E is a high‑precision rotor assembly built with premium ceramic bearings. Ceramic bearings offer lower friction, reduced heat generation and longer service life compared with conventional steel bearings, ensuring consistent and smooth rotation throughout extended clinical use. Under the recommended working air pressure of 0.22–0.30 MPa, the handpiece maintains a stable operating speed of 280,000–350,000 rpm, delivering sufficient cutting power for most routine restorative procedures. Overall working noise is kept at ≤60 dB, contributing to a quieter, more comfortable experience for both dentist and patient.
2. Shadowless LED Illumination
The handpiece features a built‑in integrated LED light system with brightness of ≥2500 Lux. The ring‑shaped LED design delivers 100 % shadowless illumination directly onto the preparation site, so dentists can clearly observe cavity margins, tooth structure and fine cutting details without relying on external auxiliary lighting. This improves visibility, enhances treatment accuracy and reduces eye strain during long procedures.
3. 5‑Water‑Spray Cooling System
One of the standout features of the BR‑164AS‑E is its 5‑port water spray cooling system. Five independent water outlets are evenly distributed around the bur head, surrounding the bur with a continuous water curtain during operation. This design provides:
Efficient bur cooling — prevents bur overheating and premature wear
Dental tissue protection — reduces the risk of thermal injury to the pulp and surrounding hard tissue
Effective debris removal — continuously flushes away grinding dust and cutting residue, maintaining a clear operating field
4. Push‑Button Chuck & Three Head Size Options
The handpiece uses a push‑button chuck mechanism, enabling fast, single‑handed bur installation and removal. It is fully compatible with standard dental burs of Φ1.595–Φ1.60 mm shank diameter, fitting seamlessly into everyday clinical workflows.
To accommodate diverse clinical needs, the BR‑164AS‑E is offered in three head sizes:
表格
Head Size
Head Diameter
Head Height
Best For
Small 13.5 mm 10.35 mm Pediatric dentistry, posterior region access, minimally invasive preparation
Middle 13.8 mm 11.5 mm General restorative work, balanced torque and visibility
Big 13.6 mm 12.5 mm High‑torque cutting, crown and bridge preparation, heavy‑duty grinding
5. Ergonomic Design & Premium Finish
The body of the BR‑164AS‑E features a matte black anti‑slip grip section paired with a polished silver metal housing, creating an elegant and modern appearance. The curved, slim handle profile follows natural hand ergonomics, providing a secure, comfortable grip that reduces hand and wrist fatigue during long treatment sessions.
6. Autoclavable & Hygiene‑Ready
The entire handpiece body is fully autoclavable at 135 °C, supporting standard dental sterilization protocols and ensuring strict infection control in clinical settings. The corrosion‑resistant metal construction withstands repeated autoclave cycles without compromising performance or surface finish.
7. Compatibility & Maintenance
The BR‑164AS‑E connects to standard 4‑hole dental chair tubing, making it compatible with most mainstream dental units worldwide. Its modular rotor design allows for straightforward inspection and replacement by dental technicians, simplifying routine maintenance and extending the overall service life of the handpiece.
With its balanced performance, versatile head size options, reliable 5‑spray cooling and shadowless LED illumination, the WISEGENT BR‑164AS‑E is a cost‑effective, all‑around high‑speed handpiece suitable for private dental clinics, dental hospitals and teaching institutions.
