Why Choose Cool-Diamant?
The Cool-Diamant series by Busch is engineered in Germany to deliver reliable cutting performance across demanding clinical scenarios. The coarse grit formulation of this coarse diamond dental bur crown preparation instrument allows for rapid material removal, reducing chair time and operator fatigue. The pointed tip geometry provides access to anatomical areas that require targeted preparation.
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.
