Busch Cool-Diamant Pointed Bur | Busch No. CD 55G 018 – Coarse Grit – FG | Pack of 6
The coarse diamond dental bur crown preparation solution from Busch & Co. GmbH — the CD 55G 018 FG COOL-DIAMANT — is engineered for clinicians who demand precision, efficiency, and consistent performance in demanding restorative procedures. Supplied in a convenient pack of six, this instrument is designed to meet the rigorous standards of modern dental practice.
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 is a pointed, diamond-grit instrument featuring a coarse grit specification and identified by its distinctive green ring coding. As a trusted coarse diamond dental bur crown preparation tool, it delivers aggressive yet controlled material removal, making it ideal for full crown preparations and related restorative workflows.
Key Applications
- Crown Preparation: Optimized geometry and coarse diamond grit allow for efficient tooth reduction and precise margin definition during crown preparation procedures.
- Filling Treatment: Suitable for preparatory steps associated with filling treatment, enabling smooth and accurate cavity access and refinement.
Product Features
- Diamond-coated pointed design (Cool Diamant series)
- Coarse grit for efficient material removal
- Green ring identification for easy grit-grade recognition
- FG (Friction Grip) shank for compatibility with standard high-speed handpieces
- Pack of 6 — cost-effective for busy clinical environments
- Made in Germany — manufactured to rigorous European quality standards
Why Choose This Bur?
As a coarse diamond dental bur crown preparation instrument made in Germany, the CD 55G 018 FG COOL-DIAMANT reflects Busch & Co. GmbH's long-standing commitment to precision engineering. The Cool Diamant series is recognized for consistent diamond bonding and predictable cutting performance across a wide range of clinical applications.
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 pointed (needle) head opens fissures, slices interproximally and refines fine occlusal anatomy; the gold COOL DIAMANT head carries cooling grooves that keep heat down while cutting. At 1.8 mm the head is on the larger side, suited to posterior teeth and fast reduction. Coarse grit removes material quickly, so this is the bur for the bulk-reduction stage before switching to medium or fine grit.
