Busch Cool-Diamant Torpedo Bur | Busch No. CD 69 012 – FG | Pack of 6
The cool diamant diamond dental bur CD 69 012 FG from Busch & Co. is a precision-engineered torpedo-shaped diamond instrument designed to meet the exacting demands of crown preparation procedures. As a cool diamant diamond dental bur, it combines a torpedo geometry with medium grit diamond abrasive, delivering controlled, efficient cutting with minimal heat generation during clinical use.
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.
Key Features
- Shape: Torpedo (CD 69 series)
- Grit: Medium — suitable for controlled crown preparation and shaping
- Shank: FG (Friction Grip) for standard high-speed handpiece compatibility
- Pack Size: 6 burs per pack, providing excellent value for busy clinical environments
- Design: Cool Diamant technology for optimized cutting performance
Crown Preparation
The torpedo profile of this cool diamant diamond dental bur is particularly well suited to crown preparation, enabling the clinician to create well-defined margins and smooth axial walls with consistent results. The medium grit configuration balances material removal rate with surface finish quality, supporting efficient workflows in restorative dentistry.
Made in Germany
Manufactured in Germany by Busch & Co. GmbH, this instrument reflects the precision engineering and quality standards that have defined the Busch brand. German-made production ensures strict dimensional tolerances and consistent diamond bond quality across every bur in the pack.
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. As a medium-grit instrument it carries the main part of the preparation once bulk reduction is done.
