Busch Cool-Diamant Torpedo Bur | Busch No. CD 66 012 – FG | Pack of 6
The cool diamant diamond dental bur CD 66 012 FG is a torpedo-shaped, medium-grit diamond instrument engineered for precise crown preparation procedures. Designed under the Cool Diamant system, this bur delivers efficient cutting with reduced heat generation, supporting patient comfort and procedural accuracy in demanding 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.

The torpedo tip is designed for chamfer margins, blending the axial wall into a smooth, well-defined finish line, and its COOL DIAMANT cooling grooves reduce heat build-up in use. At 1.2 mm the head is narrow, which favours anterior preparations and confined spaces. Medium grit is the standard working grit for the main preparation after gross reduction.
