Busch Cool-Diamant Pointed Bur | Busch No. CD 55G 014 – Coarse Grit – FG | Pack of 6
The coarse diamond dental bur crown preparation specialist from Busch & Co. GmbH, the CD 55G 014 FG COOL-DIAMANT (Pack of 6), is engineered to deliver precise, efficient cutting performance in demanding clinical environments. Designed with a pointed tip geometry and coarse grit diamond abrasive, this bur is built for clinicians who require reliable material removal during crown preparation and related restorative 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.

Applications
The coarse diamond dental bur crown preparation is well-suited for the following clinical procedures:
 |
Crown Preparation — Reduction of tooth structure to create the margins and clearance required for a crown. |
 |
Filling Treatment — Contouring, finishing and polishing of amalgam and composite restorations. |
Why Choose Busch COOL-DIAMANT?
The COOL-DIAMANT series from Busch & Co. GmbH is formulated for reduced heat generation during use, helping to protect pulpal health and improve patient comfort. The coarse diamond dental bur crown preparation design ensures consistent diamond bond retention and longevity across multiple uses.
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. A 1.4 mm head is a mid-range size that works on both anterior and posterior preparations. The coarse diamond coating is meant for fast, gross reduction; follow with a medium or fine instrument to refine the preparation.
