Busch Cool-Diamant Pointed Bur | Busch No. CD 55 018 – FG | Pack of 6
The Busch diamond dental bur medium grit CD 55 018 FG Cool-Diamant is a precision-engineered rotary instrument designed to meet the exacting demands of modern dental practice. Manufactured by Busch & Co. GmbH in Germany, this bur combines a pointed diamond tip with a Cool-Diamant coating technology for controlled, efficient cutting performance.
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.
Key Features
- Shape: Diamond, Pointed — optimised for access and precision in confined intraoral areas
- Grit: Medium — the ideal balance between efficient material removal and surface refinement
- Shank: FG (Friction Grip) — compatible with standard high-speed handpieces
- Cool-Diamant technology: Engineered to support reduced heat generation during cutting procedures
- Made in Germany: Manufactured to stringent German quality standards
- Pack of 6: Supplied in a convenient multi-unit pack for clinical efficiency
Clinical Applications
This Busch diamond dental bur medium grit instrument is well-suited to two primary clinical procedures:
- Crown Preparation: The pointed geometry and medium grit facilitate precise tooth reduction and margin definition during crown preparation workflows.
- Filling Treatment: Effective for shaping and finishing composite or other restorative materials as part of filling treatment protocols.
Why Choose Cool-Diamant?
The Cool-Diamant series from Busch reflects a commitment to consistent diamond particle distribution and reliable cutting behaviour across multiple uses. As a Busch diamond dental bur medium grit product, the CD 55 018 delivers the quality and repeatability that clinicians and dental technicians expect from a German-engineered instrument.
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. The 1.8 mm head is a larger size, best for posterior bulk reduction where there is room to work. The medium coating balances removal rate and surface quality, making it the all-round grit for the main preparation.
