Busch Cool-Diamant Torpedo Bur | Busch No. CD 72 012 – FG | Pack of 6
The cool diamant diamond dental bur CD 72 012 FG from Busch & Co. GmbH is a precision torpedo-shaped instrument engineered for crown preparation procedures. Designed with a medium grit diamond coating, this bur delivers controlled, consistent cutting performance 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.
Product Overview
The cool diamant diamond dental bur features a torpedo geometry that facilitates accurate crown preparation with minimal lateral stress on surrounding tooth structure. The Cool Diamant designation reflects a design optimized for efficient heat dissipation during high-speed cutting, supporting patient comfort and instrument longevity.

German Engineering Quality
Manufactured in Germany 
, the CD 72 012 FG upholds the rigorous quality standards associated with Busch & Co. GmbH. Each cool diamant diamond dental bur is crafted to maintain dimensional consistency across the entire pack, ensuring predictable clinical outcomes with every procedure.
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. As a medium-grit instrument it carries the main part of the preparation once bulk reduction is done. The 1.2 mm head is a slim size, suited to anterior teeth, narrow interproximal spaces and detail work.
