GmbH's longstanding reputation for precision and quality in dental instrumentation. The FG shank is compatible with standard high-speed handpieces used in most clinical settings.
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
For callus and nail smoothing on a turbine unit, Busch lists the CD 34 014, a 1.4 mm cylinder round Cool-Diamant bur in medium grit. Peripheral cooling grooves are part of the design, and Busch specifies use only in turbines with cooling water. See podiatry burs for nail-edge and fine work and diamond podiatry 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. A 1.4 mm head is a mid-range size that works on both anterior and posterior preparations. The medium coating balances removal rate and surface quality, making it the all-round grit for the main preparation.
