Busch Cool-Diamant Pointed Bur | Busch No. CD 54G 014 – Coarse Grit – FG | Pack of 6
The coarse diamond dental bur crown preparation instrument from Busch & Co. GmbH is engineered for clinicians who demand precision, consistency, and control during demanding restorative procedures. Designed in a pointed (tapered) form factor, this Cool-Diamant bur delivers efficient cutting performance while minimizing heat generation at the preparation site.
Product Overview
- Type: Diamond, Pointed
- Series: Cool-Diamant
- Grit: Coarse (Green Ring)
- Shank: FG (Friction Grip)
- Pack Quantity: Pack of 6
- Made in Germany
Key Applications
This coarse diamond dental bur crown preparation tool is ideally suited for two primary clinical applications:
- Crown Preparation: Achieve accurate, well-defined margins and consistent taper for full-coverage restorations.
- Filling Treatment: Efficiently remove existing restorative material and refine cavity walls prior to new restorations.
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.
Why Choose Cool-Diamant?
The Cool-Diamant designation reflects Busch's commitment to reducing frictional heat during high-speed cutting. As a coarse diamond dental bur crown preparation instrument, it is well suited for initial bulk reduction where rapid material removal is required. The green ring coding provides immediate visual identification of grit classification, supporting efficient instrument management in a busy clinical environment.
Manufactured in Germany, this bur upholds the quality standards associated with German dental engineering — offering reliable diamond bonding, consistent grit distribution, and compatible FG shank geometry for use with standard high-speed handpieces.
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.

FAQ
What does the green ring indicate? The green ring is the ISO standard color code for coarse grit, signifying aggressive cutting capability suitable for rapid enamel and dentin reduction.
Is this bur compatible with standard high-speed handpieces? Yes. The FG (Friction Grip) shank is designed for use with conventional high-speed dental handpieces.
How many burs are included? Each pack contains 6 individual coarse diamond dental bur crown preparation instruments.
