Busch Cool-Diamant Taper (Cone) Rounded Edge Bur | Busch No. CD 42G 016 – Coarse Grit – FG | Pack of 6
The coarse diamond dental bur taper (cone) rounded edge from Busch & Co. GmbH is a precision rotary instrument engineered for demanding crown preparation workflows in modern clinical dentistry. Designed with a taper (cone) rounded edge geometry, this bur delivers controlled, efficient material removal while maintaining predictable margins throughout the preparation process.
Product Overview
The CD 42G 016 FG COOL-DIAMANT is a coarse grit diamond instrument featuring a green ring designation, which indicates its coarse grit classification for aggressive initial reduction. The taper (cone) rounded edge profile makes it particularly well-suited for crown and full-coverage preparation techniques where smooth transitions and accurate axial walls are essential.

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.
