Why Choose the Cool Diamant Diamond Dental Bur?
The cool diamant diamond dental bur is part of Busch's renowned Cool Diamant series, developed to provide optimal cutting efficiency while minimizing heat generation during preparation. The torpedo geometry offers clinicians excellent access and visibility, making it well suited for a wide range of crown preparation techniques. Medium grit ensures a balance between material removal rate and surface finish quality.
Each instrument is manufactured in Germany, reflecting Busch & Co. GmbH's longstanding commitment to precision engineering and quality standards expected by dental professionals worldwide. The FG shank ensures compatibility with standard high-speed handpieces commonly used in modern dental operatories.
Clinical Application
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.

The torpedo tip is designed for chamfer margins, blending the axial wall into a smooth, well-defined finish line; the gold COOL DIAMANT head carries cooling grooves that keep heat down while cutting. Medium grit is the standard working grit for the main preparation after gross reduction. A 1.4 mm head is a mid-range size that works on both anterior and posterior preparations.
