The DIAO - KP6379 is an egg/football-shaped coarse diamond used for crown preparation.
Perfect your preps with the KP6379, a next-generation diamond designed with pearls for precise cutting, excellent control and long-lasting sharpness. Its unique, rose-gold colour makes it easily identifiable.
Features:
- Efficiently removes tooth structure with less pressure and more control
- Perform procedures faster with DIAO which has a 27% greater initial sharpness compared to competing instruments*
- Produces less heat and saves healthy tooth structure
- A coarse diamond without the chatter
- Reduces dental build up, making it easier to clean and reprocess
S-Diamond to DIAO Conversion:

Directions for use:
- Use at an optimum speed of 160,000 rpm, preferably in a red contra-angle or, alternatively, in a turbine. Instruments subject to a speed limit of 300,000 rpm are not authorized for use in a turbine (e.g., KP6370.314.030/035 or KP6845KR.314.025—see information on the label).
- Always provide sufficient spray cooling of at least 50 ml/min.
- For good preparation results, the surface should be smoothed with a finisher of matching shape after the initial preparation.
- The instruments remove substance very effectively. Therefore, only low pressure (< 2 N) needs to be applied during use.
Concentrated cutting performance for optimum control and long lasting, effective substance removal.
DIAO is much easier to handle and impresses the user with its smooth operation and the way it glides over the tooth. Although easy to control, DIAO instruments remove substance consistently and at greater speed.
Efficiency Created from Diamonds and Pearls.
The innovative diamond coating of DIAO burs is interspersed with ceramic pearls. This concentrates pressure on the tips of the diamond grains, greatly increasing their cutting efficiency.
34% Longer average service life 27% Greater initial sharpness
