Why Choose the Cool-Diamant Series?
The Cool-Diamant line from Busch is crafted to minimize heat generation during cutting, reducing thermal stress on pulpal tissue and surrounding structures. The fine grit designation makes this cool diamant fine grit diamond dental bur particularly well suited for finishing passes and detail work where surface quality is paramount. German engineering ensures consistent diamond particle distribution and reliable shank tolerances for smooth, vibration-free operation in high-speed handpieces.
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.
