Busch Cool-Diamant Cylinder Flat Bur | Busch No. CD 21 012 – FG | Pack of 6
The cool diamant diamond dental bur medium grit from Busch & Co. GmbH offers clinicians a reliable, precision-engineered instrument for demanding restorative and preparatory procedures. Designed in a cylinder rounded edge configuration, this bur delivers controlled, consistent cutting action suited to a wide range of clinical applications.
Product Overview
The CD 21 012 FG is part of the Cool-Diamant series — a line engineered for efficient material removal while minimizing heat generation at the preparation site. The medium grit designation makes this cool diamant diamond dental bur medium grit an ideal choice for standard crown and cavity preparations where a balance of cutting speed and surface refinement is required.
Key Applications
- Crown Preparation: The cylinder rounded edge geometry provides accurate, smooth margins essential for full-coverage restorations.
- Cavity/Fissure Preparation: The bur's geometry and grit allow efficient access and shaping within cavities and fissures, supporting precise preparation outlines.

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.
