Busch Cool-Diamant Cylinder Round Bur | Busch No. CD 33 014 – FG | Pack of 6
The cool diamant diamond dental bur cylinder round medium grit from Busch & Co. GmbH is a precision rotary instrument engineered for consistent, controlled crown preparation procedures. Designed with a cylindrical round geometry and medium grit diamond coating, this bur delivers reliable cutting performance across a wide range of clinical applications.
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 cool diamant diamond dental bur cylinder round medium grit is part of the Cool-Diamant series — a product line developed to balance efficient material removal with reduced heat generation during preparation. The medium grit formulation provides an optimal combination of speed and surface refinement, making it well-suited for full crown and partial crown preparation techniques.
- Shape: Cylinder Round
- Series: Cool-Diamant
- Grit: Medium
- Application: Crown Preparation
- Shank: FG (Friction Grip)
- Pack Size: 6 burs per pack
- Origin: Made in Germany
Clinical Application
The cylinder round geometry of the cool diamant diamond dental bur cylinder round medium grit supports precise axial wall preparation, offering clinicians a dependable tool for achieving consistent reduction depths and smooth preparation margins. The FG friction grip shank ensures compatibility with standard high-speed handpieces used in modern dental practices.
German Engineering
Manufactured in Germany, this instrument reflects the quality standards associated with Busch & Co. GmbH, a trusted name in dental rotary instrumentation. Each bur in the pack is produced to exacting tolerances, supporting predictable clinical outcomes.
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
One size up from the CD 33 012, the CD 33 014 is a cylinder round bur that Busch lists for callus and nail smoothing. The 1.4 mm Cool-Diamant diamond has medium grit and peripheral cooling grooves for a cool, soft treatment on water-cooled turbines. Browse diamond podiatry burs or podiatry burs for nail-edge and fine work.

The cylinder round head cuts parallel axial walls and leaves a rounded-shoulder margin in a single pass, which is why this figure is a crown-preparation workhorse, 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. Medium grit is the standard working grit for the main preparation after gross reduction.
