Busch Cool-Diamant Torpedo Bur | Busch No. CD 69G 014 – Coarse Grit – FG | Pack of 6
The cool diamant coarse diamond dental bur from Busch & Co. GmbH is a precision-engineered rotary instrument designed to meet the demanding standards of modern restorative and prosthodontic dentistry. Featuring a torpedo shape and coarse grit designation identified by a green ring, this bur delivers aggressive, efficient material removal while maintaining clinician control throughout the preparation process.
Product Overview
- Shape: Torpedo (CD 69G)
- Grit: Coarse (Green Ring)
- Shank: FG (Friction Grip)
- Size: 014
- Pack Quantity: 6 burs per pack
- Primary Use: Crown Preparation
Key Features
The cool diamant coarse diamond dental bur is manufactured in Germany, reflecting Busch's longstanding commitment to precision and quality. German-engineered manufacturing processes ensure consistent diamond particle distribution, reliable grit performance, and dimensional accuracy across every bur in the pack. The coarse grit configuration makes this instrument particularly suitable for rapid bulk reduction during crown preparation procedures.
The torpedo geometry provides a geometry well-suited to creating defined finish lines and contouring axial walls during full-coverage restoration preparation. The FG friction grip shank ensures compatibility with standard high-speed handpieces used in clinical environments.
Instrument Dimensions
| Head Ø | 1.4 mm (ISO size 014) |
|---|---|
| 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 coarse diamond dental bur is indicated primarily for crown preparation, where efficient enamel and dentin reduction is required. The coarse grit allows clinicians to achieve rapid initial reduction before transitioning to finer finishing instruments.
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.
