Busch Cool-Diamant Taper (Cone) Rounded Edge Bur | Busch No. CD 36 018 – FG | Pack of 6
The cool diamant taper (cone) diamond dental bur from Busch & Co. GmbH is a precision-engineered rotary instrument designed to meet the demands of modern restorative and prosthodontic dentistry. Featuring a taper (cone) rounded edge geometry and medium grit diamond coating, this bur delivers controlled, efficient cutting with minimal heat generation — a hallmark of the Cool Diamant series.
Key Features
- Shape: Taper (Cone) with rounded edge for smooth, predictable preparation contours
- Grit: Medium — suitable for general crown and cavity preparation procedures
- Series: Cool Diamant — engineered for reduced heat transfer to pulpal tissue during cutting
- Shank: FG (Friction Grip) — compatible with standard high-speed handpieces
- Pack Quantity: 6 burs per pack
- Made in Germany — manufactured to strict quality standards
Instrument Dimensions
| Head Ø | 1.8 mm (ISO size 018) |
|---|---|
| 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 Applications
This cool diamant taper (cone) diamond dental bur is well suited for two primary clinical procedures:
- Crown Preparation — Precise axial wall and occlusal reduction with consistent taper
- Cavity / Fissure Preparation — Accurate cavity outline and fissure extension for composite or ceramic restorations
The taper (cone) rounded edge profile facilitates smooth margin definition, reducing the need for secondary finishing steps. As a cool diamant taper (cone) diamond dental bur, it is particularly valued in procedures where minimising thermal stress to the tooth structure is a clinical priority.
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.
