Busch Cool-Diamant Pointed Bur | Busch No. CD 55G 016 – Coarse Grit – FG | Pack of 6
The coarse diamond dental bur crown preparation instrument from Busch & Co. GmbH — the CD 55G 016 FG Cool-Diamant — is engineered for clinicians who demand precision and efficiency in restorative and prosthodontic workflows. This pointed diamond bur, featuring a coarse grit and a distinctive green ring designation, is optimized for aggressive yet controlled tooth reduction during crown preparation procedures.
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
- Shape: Pointed (tapered point geometry)
- Grit: Coarse (green ring)
- Series: Cool-Diamant (CD)
- Shank: FG (friction grip, high-speed handpiece compatible)
- Pack Contents: 6 burs per pack

Clinical Applications
As a coarse diamond dental bur crown preparation solution, the CD 55G 016 FG is well-suited for two primary clinical procedures:
- Crown Preparation — Efficient bulk reduction and shoulder or chamfer margin definition
- Filling Treatment — Preparation and finishing of restorative cavities where coarse diamond cutting is indicated
Why Choose Cool-Diamant?
The Cool-Diamant series by Busch is engineered in Germany to deliver reliable cutting performance across demanding clinical scenarios. The coarse grit formulation of this coarse diamond dental bur crown preparation instrument allows for rapid material removal, reducing chair time and operator fatigue. The pointed tip geometry provides access to anatomical areas that require targeted preparation.
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. Being coarse, it is a bulk-reduction instrument rather than a finishing one. A 1.6 mm head is a mid-range size that works on both anterior and posterior preparations.

FAQ
What does the green ring indicate on this bur?
The green ring is the ISO color-coding standard designating a coarse grit diamond bur, confirming aggressive cutting capability suitable for bulk tooth reduction.
Is this bur compatible with standard high-speed handpieces?
Yes. The FG (friction grip) shank is the universal standard for high-speed dental handpieces used in clinical practice.
How many burs are included in a pack?
Each pack contains 6 individual coarse diamond dental bur crown preparation instruments, offering excellent value for busy dental practices.
