Busch Cool-Diamant Torpedo Bur | Busch No. CD 69G 012 – Coarse Grit – FG | Pack of 6
The cool diamant coarse diamond dental bur from Busch & Co. GmbH is engineered to deliver reliable, controlled crown preparation with a torpedo shape and coarse grit formulation. Identified by its distinctive green ring, this instrument is purpose-built for clinicians who demand consistency and precision in their restorative workflow.
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.

Clinical Application
This cool diamant coarse diamond dental bur is specifically designed for crown preparation procedures, where consistent stock removal and a smooth preparation margin are essential. The torpedo geometry provides optimal access and angulation, while the coarse diamond grit facilitates efficient cutting through hard dental tissues. Each bur in this pack of 6 is manufactured to the exacting standards associated with German engineering, ensuring reproducible clinical performance across every use.
Why Choose Cool Diamant?
The Cool Diamant series by Busch is recognized for its quality and durability. Choosing a cool diamant coarse diamond dental bur means investing in an instrument that maintains cutting efficiency throughout its intended service life. The green ring coding provides quick, reliable grit identification at the chairside, minimizing setup errors and improving workflow efficiency.
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. The coarse diamond coating is meant for fast, gross reduction; follow with a medium or fine instrument to refine the preparation. At 1.2 mm the head is narrow, which favours anterior preparations and confined spaces.
