Busch Cool-Diamant Torpedo Bur | Busch No. CD 66G 010 – Coarse Grit – FG | Pack of 6
The cool diamant coarse diamond dental bur from Busch & Co. is a precision-engineered rotary instrument designed to meet the demanding standards of modern restorative and prosthetic dentistry. Featuring a torpedo shape and coarse grit, this bur delivers aggressive, efficient material removal while maintaining control throughout crown preparation procedures.
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.

About the Cool-Diamant Series
The cool diamant coarse diamond dental bur belongs to Busch's renowned Cool-Diamant line, engineered in Germany for reliable clinical performance. The diamond abrasive surface ensures consistent cutting efficiency, reduced heat generation, and extended instrument longevity — all critical factors in everyday clinical use. The green ring color-coding provides instant grit identification, streamlining instrument selection chairside.
Clinical Application
This instrument is specifically suited for crown preparation, where efficient and controlled tooth reduction is essential. As a cool diamant coarse diamond dental bur, it supports initial gross reduction while the torpedo geometry facilitates shoulder and chamfer margin definition with precision.
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. At 1.0 mm the head is narrow, which favours anterior preparations and confined spaces. Coarse grit removes material quickly, so this is the bur for the bulk-reduction stage before switching to medium or fine grit.
