Premium LUX E Increasing Contra-Angle— 1:5 / 1:4.2

Speed-increasing advantages
A precision gearbox converts 40,000 rpm input to high bur speeds—~200,000 min⁻¹ at 1:5 and ~168,000 min⁻¹ at 1:4.2—delivering turbine-like efficiency with electric control for veneers, crowns, onlays, and margin refinement.

Compact access & visibility
The Ø10.0 × H14.5 mm head and fiber-optic light-guide enhance sightlines in aesthetic zones while preserving hand-clearance—on par with premium small-head competitors (e.g., NSK S-MAX™ M95L 1:5, Head Ø9.9 × H14.5 mm, Quattro Spray, max 200k min⁻¹).

Thermal management at high RPM
An internally guided, 4-nozzle spray directs coolant to the cutting interface, controlling heat and debris at elevated speeds.

Built for service life
Titanium coating + stainless steel structure, DLC gear coating, ceramic bearings, and a push-button FG collet minimize vibration and wear; the anti-retraction hygiene head helps block fluid backflow. Thermodisinfectable and autoclavable to 135 °C. 

FAQ (SEO-friendly, precise)

1) What does "speed-increasing" mean in practice?
A gearbox multiplies the RPM of an electric micromotor (e.g., 40,000 rpm input → ~200,000 min⁻¹ at 1:5), providing turbine-like cutting with consistent electric control.

2) Should I choose 1:5 or 1:4.2?
Pick 1:5 for the highest finishing speed; choose 1:4.2 for slightly lower peak speed with more tactile margin control (≈168,000 min⁻¹ from a 40k motor).

3) How does the head size compare to well-known models?
Premium LUX E: Ø10.0 × H14.5 mm. Targets improved access and visibility in anterior/posterior zones.

4) How is heat managed at high rpm?
The internally guided, 4-nozzle spray system delivers targeted coolant to the bur and workpiece to manage heat and debris efficiently.

5) Which burs and motors are supported?
FG Ø1.6 mm friction-grip burs; ISO E-Type electric micromotors (ensure your unit provides light if fiber-optic illumination is required).

6) What durability features are built in?
Titanium/stainless construction, DLC-coated gears, ceramic bearings, push-button FG collet, and an anti-retraction head; autoclavable to 135 °C.

• 45° Angle Head- The 45° angled head allows easy access to the molar region, minimizing interference from the front and adjacent teeth.
• With an enclosed dedicated tool, the two-way spray function enables you to instantly switch between a mist and jet spray, depending on the conditions and procedure. The water jet spray prevents subcutaneous emphysema and mist in surgical procedures. Water Jet Mist spray effectively cools the bur while cutting.
• Handling a wide range of burs from 20mm standard bur to 25mm long bur, depending on the procedure's requirements.
• 45° angled Head provides effortless access to hard-to-reach molars that a standard contra-angle can't match.
• Premium LUX E142L's powerful and consistent cutting shortens treatment time for time-consuming sectioning and third-molar extractions compared to standard contra-angles, dramatically reducing stress for clinicians and patients.
