- Type: Diamond (Cool-Diamant)
- Grit: Coarse
- Identification: Green Ring
- Shank: FG (Friction Grip)
- Pack Quantity: 6 burs per pack
Key Features
The coarse diamond dental bur pear shaped Cool-Diamant series is engineered for effective cavity preparation and fissure shaping. The coarse grit ensures rapid material removal, making it well-suited for initial preparation stages where speed and precision are both essential. The green ring coding allows for quick, reliable identification chairside, reducing the risk of instrument mix-ups during clinical workflows.
Manufactured in Germany, this instrument reflects the high standards of precision and quality associated with German dental engineering. The FG shank is compatible with standard high-speed handpieces, ensuring broad clinical applicability.
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 coarse diamond dental bur pear shaped instrument is indicated primarily for cavity and fissure preparation, where accurate tooth reduction and consistent cutting geometry are critical to achieving reliable restorative outcomes. The pear shape provides access and angulation suited to specific cavity forms.
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 pear head is used for occlusal reduction and for opening and shaping cavity preparations, and its COOL DIAMANT cooling grooves reduce heat build-up in use. At 1.2 mm the head is narrow, which favours anterior preparations and confined spaces. Coarse grit removes material quickly, so this is the bur for the bulk-reduction stage before switching to medium or fine grit.
