Applications
The cool diamant taper (cone) round diamond dental bur is well suited for crown preparation and cavity/fissure preparation, providing clinicians with reliable, repeatable results. Its taper (cone) round form factor allows precise access to interproximal regions and occlusal anatomy.
The cool diamant taper (cone) round diamond dental bur is well-suited for the following clinical procedures:
 |
Cavity/Fissure Preparation — Opening, extending and shaping cavities and fissures with controlled removal of enamel and dentin. |
 |
Crown Preparation — Reduction of tooth structure to create the margins and clearance required for a crown. |
German Engineering You Can Trust
Every cool diamant taper (cone) round diamond dental bur in the CD45 014 FG range is manufactured in Germany, reflecting Busch & Co.'s long-standing commitment to quality, precision, and consistency. The Cool-Diamant line is specifically developed to minimize thermal stress on vital tooth structure during high-speed preparations.
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 round-ended taper creates convergent axial walls with a rounded chamfer margin and is a common choice for full-crown preparation, and its COOL DIAMANT cooling grooves reduce heat build-up in use. The 1.4 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.
