Busch Cool-Diamant Torpedo Bur | Busch No. CD 72F 012 – Fine Grit – FG | Pack of 2
The cool diamant fine diamond dental bur from Busch & Co. GmbH is engineered for precise, controlled crown preparation in demanding clinical environments. Designed in a Torpedo shape with a Fine Grit and identified by its distinctive Red Ring, this instrument delivers consistent cutting performance for practitioners who require reliability and accuracy.
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.

Designed for Crown Preparation
The cool diamant fine diamond dental bur is specifically suited for crown preparation procedures, offering smooth, refined cutting action that minimises heat generation and supports consistent marginal definition. The Fine Grit configuration makes it ideal for finishing and refining preparations where surface quality is critical.
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. |
Made in Germany
This instrument is proudly manufactured in Germany, reflecting Busch & Co. GmbH's longstanding commitment to quality craftsmanship and precision engineering. 
German manufacturing standards ensure that each cool diamant fine diamond dental bur meets exacting tolerances for consistent clinical outcomes.
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. Fine grit is a finishing grit: it smooths walls and margins after preparation rather than removing bulk. The 1.2 mm head is a slim size, suited to anterior teeth, narrow interproximal spaces and detail work.
