Busch Cool-Diamant Taper (Cone) Round Bur | Busch No. CD 51G 018 – Coarse Grit – FG | Pack of 6
The coarse diamond dental bur taper (cone) round from Busch & Co. GmbH — the CD 51G 018 FG COOL-DIAMANT — is a precision-engineered rotary instrument designed to meet the demanding standards of modern restorative and prosthodontic dentistry. Engineered with a taper (cone) round geometry and a coarse grit diamond coating, this bur delivers efficient, controlled material removal for crown preparation and similar clinical procedures.
Product Overview
The coarse diamond dental bur taper (cone) round features a green ring color-coding, which universally denotes coarse grit — ideal for rapid bulk reduction of enamel and dentin during initial preparation stages. The Cool-Diamant technology is specifically developed to reduce heat generation during cutting, helping protect pulpal health and supporting patient comfort throughout the procedure.

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.

FAQ
What does the green ring indicate on this bur? The green ring color-coding universally indicates coarse grit, meaning the bur is designed for efficient, rapid material removal rather than fine finishing.
What is the FG shank type? FG stands for Friction Grip, a standard shank type compatible with high-speed contra-angle and turbine handpieces used in most dental practices.
How many burs are included? This product is sold as a pack of 6 burs, providing excellent clinical value for busy practices.
