Busch Cool-Diamant Taper (Cone) Rounded Edge Bur | Busch No. CD 42G 016 – Coarse Grit – FG | Pack of 6
The coarse diamond dental bur taper (cone) rounded edge from Busch & Co. GmbH is a precision rotary instrument engineered for demanding crown preparation workflows in modern clinical dentistry. Designed with a taper (cone) rounded edge geometry, this bur delivers controlled, efficient material removal while maintaining predictable margins throughout the preparation process.
Independently tested. In the Medical University of Innsbruck cutting study, Busch’s cooling-groove diamond achieved the highest total cutting length of every bur tested over 40 minutes of continuous use. Read the Innsbruck Study.
Product Overview
The CD 42G 016 FG COOL-DIAMANT is a coarse grit diamond instrument featuring a green ring designation, which indicates its coarse grit classification for aggressive initial reduction. The taper (cone) rounded edge profile makes it particularly well-suited for crown and full-coverage preparation techniques where smooth transitions and accurate axial walls are essential.
- Shape: Taper (Cone) Rounded Edge
- Series: Cool-Diamant
- Grit: Coarse (Green Ring)
- Shank: FG (Friction Grip)
- Pack Quantity: 6 burs per pack
- Country of Manufacture: Made in Germany
Clinical Application
This coarse diamond dental bur taper (cone) rounded edge is optimized for crown preparation, enabling clinicians to achieve efficient tooth reduction with confidence. The Cool-Diamant series is recognized for its consistent diamond particle distribution, which supports reliable cutting performance across multiple preparations.
Whether used for initial gross reduction or shaping axial contours, the coarse diamond dental bur taper (cone) rounded edge geometry supports a streamlined preparation technique.
Why Choose Busch Cool-Diamant?
- German-engineered manufacturing for consistent quality
- Coarse grit for rapid, efficient tooth reduction
- Taper (Cone) rounded edge design for smooth marginal transitions
- FG shank compatibility with standard high-speed handpieces
- Supplied in a convenient pack of 6
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 tapered head with rounded edge cuts the slightly convergent axial walls a crown needs and leaves a chamfer at the margin, and its COOL DIAMANT cooling grooves reduce heat build-up in use. The coarse diamond coating is meant for fast, gross reduction; follow with a medium or fine instrument to refine the preparation. The 1.6 mm head is a general-purpose size for routine crown and cavity preparation.
