Key Features
The cool diamant coarse diamond dental bur is part of the Cool Diamant series, which is designed to minimize heat generation during cutting — a critical factor in protecting pulp vitality and surrounding tooth structure. The coarse grit formulation enables efficient, aggressive material removal suited for initial crown preparation and gross reduction phases.
- Optimized diamond grit distribution for efficient cutting
- Reduced heat transfer to support patient comfort and tissue safety
- Consistent bur geometry for predictable preparation margins
- Suitable for crown preparation workflows

Independent Research: Test Winner at Innsbruck
In an independent laboratory study at the Medical University of Innsbruck, Busch’s COOL DIAMANT design achieved the highest cutting performance in both test series — outperforming same-shape, same-grit diamonds from up to ten competing manufacturers. Under standardized conditions (200,000 rpm turbine, constant 152 g load, 10–40 minutes of continuous cutting on 99.5% Al₂O₃ ceramic), the COOL DIAMANT instrument removed significantly more material than burs from Diatech, Edenta, Horico and Komet (p < 0.05), and in the second series the standard Busch diamond placed second only to its cooling-groove sibling. The authors concluded that instruments with cooling grooves deliver higher grinding performance and need replacing less often.
