Busch Cool-Diamant Cylinder Rounded Edge Bur | Busch No. CD 25G 014 – Coarse Grit – FG | Pack of 6
The cool diamant coarse diamond dental bur from Busch & Co. GmbH is engineered for demanding crown preparation procedures, delivering consistent material removal with a coarse grit diamond surface. Designed in a cylinder rounded edge configuration, this instrument is ideally suited for controlled, efficient preparation in clinical environments.
Independently tested. In the Medical University of Innsbruck cutting study, Busch’s cooling-groove diamond achieved the highest total cutting length of every bur tested over 40 minutes of continuous use. Read the Innsbruck Study.

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.

With its flat end and rounded edge, this cylinder shapes axial walls and defines a shoulder or rounded-shoulder finish line; the gold COOL DIAMANT head carries cooling grooves that keep heat down while cutting. The 1.4 mm head is a general-purpose size for routine crown and cavity preparation. Being coarse, it is a bulk-reduction instrument rather than a finishing one.
