Busch Cool-Diamant Cylinder Round Bur | Busch No. CD 34 012 – FG | Pack of 6
The cool diamant diamond dental bur CD 34 012 FG from Busch & Co. GmbH is a precision-engineered rotary instrument designed for reliable crown preparation in clinical dentistry. This pack of 6 burs offers excellent value for busy dental practices requiring consistent, high-quality 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.

Made in Germany
This cool diamant diamond dental bur is manufactured in Germany, reflecting Busch & Co. GmbH's long-standing commitment to precision engineering and quality craftsmanship. German-made dental instruments are widely regarded for their dimensional accuracy, material integrity, and consistent clinical performance.
Clinical Application
The CD 34 012 FG is indicated for crown preparation, delivering controlled cutting action suitable for both full-crown and partial-crown preparations. The medium grit formulation balances material removal speed with surface finish quality, supporting efficient chair-side workflows.
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
Made for podiatry turbine work, the CD 34 012 is a cylinder round diamond with a 1.2 mm head and medium grit, used for smoothing callus and nails, and its Cool-Diamant cooling grooves are designed to keep treatment cool and soft. See diamond podiatry burs and nail-edge and fine-work burs.

The cylinder round head cuts parallel axial walls and leaves a rounded-shoulder margin in a single pass, which is why this figure is a crown-preparation workhorse; the gold COOL DIAMANT head carries cooling grooves that keep heat down while cutting. The 1.2 mm head is a slim size, suited to anterior teeth, narrow interproximal spaces and detail work. The medium coating balances removal rate and surface quality, making it the all-round grit for the main preparation.
