Carbide burs for a micromotor

Dental Contra-Angle Burs (Micromotor RA)

Professional dental contra-angle burs (micromotor – RA) in a rose/round (ball) shape, available in a wide range of sizes from 008 to 023. These burs are designed for precise clinical procedures requiring maximum control, stable performance, and reliable sharpness.

Our burs are made entirely of high-quality tungsten carbide, offering exceptional durability and resistance to wear. They provide clean cutting performance, high efficiency, and excellent comfort during clinical work.

They are available in two shank lengths:

• 22.5 mm – standard length,

• 26.5 mm – extended shank, ideal for situations requiring a longer reach.

Each bur features a 2.35 mm shank diameter with the characteristic RA notch, ensuring compatibility with RA micromotors and secure locking in the contra-angle handpiece.

Advantages of Tungsten Carbide Burs

1. Exceptional durability
Tungsten carbide is significantly harder than steel, providing a much longer lifespan while maintaining cutting performance over time.

2. Sharpness that lasts
These burs stay sharp even during intensive clinical use, ensuring smooth and precise cutting.

3. High stability and minimal deformation
The rigidity of tungsten carbide reduces vibration and provides full control over the cutting trajectory during procedures.

4. Enhanced clinical efficiency
Tungsten carbide burs allow faster and more efficient tissue removal, reducing procedure time and improving comfort for both the dentist and the patient.
