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 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, and its COOL DIAMANT cooling grooves reduce heat build-up in use. The medium coating balances removal rate and surface quality, making it the all-round grit for the main preparation. The 1.4 mm head is a general-purpose size for routine crown and cavity preparation.
