Busch Cool-Diamant Cylinder Rounded Edge Bur | Busch No. CD 25 012 – FG | Pack of 6
The cool diamant diamond dental bur cylinder rounded edge from Busch & Co. GmbH is a precision-engineered rotary instrument designed for demanding crown preparation procedures in the dental operatory. Manufactured in Germany, this bur reflects the exacting standards and craftsmanship for which German dental instrument production is renowned.
Product Overview
The CD 25 012 FG features a cylinder rounded edge geometry paired with a medium grit diamond coating — a configuration well-suited for controlled axial wall preparation and margin definition during crown and bridge work. The cool diamant diamond dental bur cylinder rounded edge design is engineered to facilitate efficient cutting while helping to manage heat generation at the preparation site, a key consideration for pulp health during restorative procedures.

Clinical Application
This cool diamant diamond dental bur cylinder rounded edge instrument is particularly suitable for full-coverage crown preparations where consistent taper, smooth axial walls, and a well-defined finish line are critical. The medium grit formulation balances cutting efficiency with surface finish quality, making it appropriate for both initial preparation and intermediate refinement steps.
As a pack of 6, the CD 25 012 FG is practical for busy clinical environments where consistent bur performance across multiple preparations is essential. The cool diamant diamond dental bur cylinder rounded edge range from Busch represents a reliable choice for clinicians who demand precision and durability from their rotary instrumentation.
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.
