Busch Cool-Diamant Taper (Cone) Rounded Edge Bur | Busch No. CD 42 016 – FG | Pack of 6
The cool diamant diamond dental bur CD 42 016 FG from Busch & Co. GmbH is a precision-engineered rotary instrument designed for reliable crown preparation in clinical dentistry. Featuring a taper (cone) rounded edge geometry and medium grit diamond coating, this bur delivers consistent, controlled cutting performance across a wide range of 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.

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. |
Why Choose the Cool Diamant Diamond Dental Bur?
The cool diamant diamond dental bur is engineered to reduce heat generation during preparation, helping to protect pulpal health and maintain patient comfort throughout the procedure. The taper (cone) rounded edge design is particularly well suited for shoulder and chamfer margin preparations, giving clinicians excellent tactile feedback and precise margin definition.
Manufactured in Germany, this instrument reflects the high-quality standards and engineering precision that Busch & Co. GmbH is known for globally. 
Made in Germany.
Clinical Application
Ideal for practitioners performing crown preparation, the cool diamant diamond dental bur in medium grit offers an optimal balance between efficient material removal and surface finish quality. The FG shank ensures compatibility with standard high-speed handpieces used in dental operatories worldwide.
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 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 medium coating balances removal rate and surface quality, making it the all-round grit for the main preparation. The 1.6 mm head is a general-purpose size for routine crown and cavity preparation.
