Busch Cool-Diamant Taper (Cone) Round Bur | Busch No. CD 51 016 – FG | Pack of 6
The cool diamant diamond dental bur taper (cone) round medium grit from Busch & Co. is a precision-engineered rotary instrument designed for demanding clinical applications, including crown preparation procedures.
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
This instrument features a taper (cone) round geometry with a medium grit diamond coating, offering a balanced combination of cutting efficiency and surface refinement. The cool diamant diamond dental bur taper (cone) round medium grit design is optimised to reduce heat generation during preparation, supporting patient comfort and tissue integrity throughout the procedure.
Key Features
- Shape: Taper (Cone) Round
- Grit: Medium
- Series: Cool-Diamant
- Application: Crown Preparation
- Shank: FG (Friction Grip)
- Pack Size: 6 burs per pack
- Made in Germany — manufactured to rigorous German quality standards
Clinical Application
The cool diamant diamond dental bur taper (cone) round medium grit is well-suited for crown preparation, providing controlled, consistent material removal on tooth structure. The taper (cone) round form factor allows access to interproximal and occlusal regions with predictable results, making it a reliable choice for restorative workflows.
Why Choose Cool-Diamant?
Busch & Co. GmbH has a long-standing reputation for precision dental instrumentation. The Cool-Diamant range reflects this heritage, delivering instruments that combine exacting geometry with high-quality diamond abrasives. Each cool diamant diamond dental bur taper (cone) round medium grit in this pack is produced in Germany, ensuring consistency across every instrument in the set.
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.

Podiatry Use
In Busch's podiatry turbine section, the CD 51 016 taper (cone) round diamond is listed with medium grit for smoothing callus and nails. Its Cool-Diamant peripheral cooling grooves aim for a cool, pleasantly soft feel, and the FG shank is for water-cooled turbines only. Browse nail-edge and fine-work burs or all diamond podiatry burs.

The round-ended taper creates convergent axial walls with a rounded chamfer margin and is a common choice for full-crown preparation; the gold COOL DIAMANT head carries cooling grooves that keep heat down while cutting. The 1.6 mm head is a general-purpose size for routine crown and cavity preparation. As a medium-grit instrument it carries the main part of the preparation once bulk reduction is done.
