Busch Cool-Diamant Torpedo Bur | Busch No. CD 72G 014 – Coarse Grit – FG | Pack of 6
The cool diamant coarse diamond dental bur from Busch & Co. GmbH is a precision-engineered rotary instrument designed for demanding crown preparation procedures in restorative and prosthodontic dentistry. Featuring a torpedo-shaped diamond tip with a coarse grit specification and a distinctive green ring color-coding, this bur delivers aggressive, efficient cutting performance where high material removal rates are required.
Product Overview
- Type: Diamond Bur – Torpedo Shape (Cool Diamant Series)
- Grit: Coarse (Green Ring)
- Application: Crown Preparation
- Shank: FG (Friction Grip)
- Pack Quantity: 6 burs per pack
- Origin: Made in Germany
Key Features
As a cool diamant coarse diamond dental bur, this instrument is engineered to minimize heat generation during cutting, helping to protect pulpal health and maintain patient comfort during preparation. The torpedo geometry provides excellent access and angulation control, making it well suited for axial wall reduction and occlusal surface shaping during crown preparation.
The green ring designation indicates a coarse grit level, which is optimal for rapid bulk reduction in the initial stages of preparation. Busch & Co. GmbH manufactures this instrument in Germany, reflecting a commitment to consistent quality, dimensional accuracy, and reliable clinical performance across the pack of six burs.

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.
