- Reference: CD 33F 012 FG
- Pack Quantity: 2 burs per pack
- Country of Origin: Made in Germany
Key Features
The cool diamant fine diamond dental bur is engineered for precise material reduction with a fine grit that promotes smooth surface finishes, making it particularly well-suited for crown preparation procedures. The red ring color-coding provides instant grit identification at the chairside, minimizing the risk of instrument selection errors during procedures.
Manufactured in Germany, this instrument reflects the high-quality craftsmanship and engineering standards associated with Busch & Co. GmbH. The fine diamond coating supports controlled abrasion, helping to preserve tooth structure while achieving the desired preparation geometry.
Instrument Dimensions
| Head Ø | 1.2 mm (ISO size 012) |
|---|---|
| Shank | FG (Friction Grip) — 1.60 mm Ø, 19 mm overall length (ISO 314) |
Per ISO 6360, the size number is the maximum head diameter in tenths of a millimeter. See our Busch Bur Size Chart for the full size conversion table, shank codes, and color ring guide.
Clinical Application
This cool diamant fine diamond dental bur is optimized for crown preparation, where smooth, accurate margins are critical to long-term restoration success. Its cylinder round form allows the clinician to refine axial walls and achieve consistent preparation depth with predictable results.
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.
