Busch Cool-Diamant Taper (Cone) Rounded Edge Bur | Busch No. CD 39 016 – FG | Pack of 6
The cool diamant diamond dental bur CD 39 016 FG from Busch & Co. GmbH is a precision-engineered rotary instrument designed for demanding crown preparation procedures. This taper (cone) rounded edge bur in medium grit delivers controlled, efficient cutting performance in a variety of clinical restorative workflows.
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 features a taper (cone) rounded edge geometry that is well suited for crown and cavity preparation, allowing the clinician to achieve accurate margins and smooth axial walls. The medium grit diamond coating provides a reliable balance between cutting speed and surface finish, making it appropriate for a wide range of restorative applications.
Applications
The cool diamant diamond dental bur is well-suited for the following clinical procedures:
| Crown Preparation — Reduction of tooth structure to create the margins and clearance required for a crown. |

- Diamond, Taper (Cone) Rounded Edge design optimised for crown preparation
- Medium grit for balanced cutting efficiency and surface quality
- FG shank compatible with standard high-speed handpieces
- Part of the Cool Diamant series — engineered for consistent clinical performance
- Made in Germany
Pack Information
This listing includes a pack of 6 units of the cool diamant diamond dental bur CD 39 016 FG, providing excellent value for high-volume clinical practices seeking consistent, reliable instruments across multiple procedures.
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
Busch also lists the CD 39 016 in its podiatry range. This 1.6 mm taper (cone) rounded edge diamond has medium grit for smoothing callus and nail surfaces, and the Cool-Diamant cooling grooves are designed for a cool, soft treatment on water-cooled turbines. Browse diamond podiatry burs or nail-edge and fine-work burs.

The tapered head with rounded edge cuts the slightly convergent axial walls a crown needs and leaves a chamfer at the margin; the gold COOL DIAMANT head carries cooling grooves that keep heat down while cutting. The 1.6 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.
