Busch Cool-Diamant Torpedo Bur | Busch No. CD 69F 014 – Fine Grit – FG | Pack of 2
The cool diamant fine diamond dental bur from Busch & Co. GmbH is a precision-engineered rotary instrument designed for demanding crown preparation procedures. Featuring a torpedo-shaped geometry and fine grit abrasive surface, this bur delivers controlled, smooth cutting action that supports consistent clinical outcomes with minimal thermal stress to the tooth structure.
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 69F)
- Grit: Fine (Red Ring designation)
- Application: Crown Preparation
- Pack Quantity: Pack of 2

Applications
The cool diamant fine diamond dental bur is well-suited for the following clinical procedures:
| Crown Preparation — Reduction of tooth structure to create the margins and clearance required for a crown. |
German craftsmanship is at the core of every cool diamant fine diamond dental bur produced under the Busch brand. The red ring color coding immediately identifies the fine grit specification, enabling efficient instrument selection chairside and reducing the risk of grit mix-ups in a busy clinical environment.
Why Choose This Bur?
When precision and reliability matter most, the cool diamant fine diamond dental bur offers the performance dental professionals expect. The torpedo form factor is particularly well-suited to shoulder and chamfer margin preparation, providing clinicians with the tactile feedback and cutting efficiency needed for high-quality restorative work.
Made in Germany
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 1.4 mm head is a general-purpose size for routine crown and cavity preparation. As a fine-grit bur it is used last, to finish the preparation surface and margin.
