Clinical Applications
This cool diamant diamond dental bur medium grit is suited for two primary clinical procedures:
- Crown Preparation: The cylinder rounded edge profile facilitates accurate reduction and finishing of tooth structure when preparing for full or partial crowns.
- Cavity/Fissure Preparation: The diamond grit and precise geometry allow controlled entry and extension for cavity and fissure preparations, supporting clean margins and minimal trauma to surrounding tissue.
Why Choose Cool-Diamant?
Busch & Co. GmbH manufactures the Cool-Diamant series to exacting German standards. The diamond coating on this cool diamant diamond dental bur medium grit is applied to deliver reliable cutting efficiency while helping to reduce excessive heat generation during use — a critical consideration for patient comfort and pulp protection.
Medium grit provides a balanced cutting rate appropriate for the bulk reduction and preliminary shaping stages of crown and cavity work, making this instrument a versatile addition to any restorative setup.
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.

With its flat end and rounded edge, this cylinder shapes axial walls and defines a shoulder or rounded-shoulder finish line; the gold COOL DIAMANT head carries cooling grooves that keep heat down while cutting. At 1.0 mm the head is narrow, which favours anterior preparations and confined spaces. Medium grit is the standard working grit for the main preparation after gross reduction.
