Busch Cool-Diamant Flame Bur | Busch No. CD 61F 016 – Fine Grit – FG | Pack of 2
The cool diamant fine grit diamond dental bur by Busch & Co. GmbH is a precision-engineered rotary instrument designed to meet the exacting demands of modern restorative and prosthodontic procedures. Featuring a flame geometry and a fine grit diamond coating identified by its distinctive red ring, this bur delivers controlled, efficient cutting with minimal heat generation — a defining advantage in sensitive 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.

Clinical Applications
This cool diamant fine grit diamond dental bur is well suited for two primary clinical procedures:
- Crown Preparation: The flame shape provides excellent access and angulation for shoulder and chamfer margin definition during full-coverage crown preparation.
- Filling Treatment: Ideal for refining cavity margins, contouring composite restorations, and finishing at the gingival margin with precision and tactile control.
Why Choose Cool-Diamant?
The Cool-Diamant series is engineered in Germany to reduce frictional heat during tooth preparation, helping to protect pulpal health while maintaining cutting efficiency. The fine grit designation makes this cool diamant fine grit diamond dental bur particularly appropriate for finishing and refining steps where surface quality and marginal accuracy are critical.
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 flame shape follows interproximal and occlusal anatomy and refines contours and margins, and its COOL DIAMANT cooling grooves reduce heat build-up in use. The 1.6 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.
