Busch COOL DIAMANT Low-Heat Diamond Bur Collection

关于

The Busch COOL DIAMANT Diamond Bur collection represents a breakthrough in German dental engineering, combining biocompatible gold coating with advanced cooling technology to deliver superior grinding efficiency and enhanced patient comfort. These instruments are designed for clinicians who demand precision, safety, and reliability in every procedure. Innovative Cooling Technology Each Busch COOL DIAMANT Diamond Bur features asymmetrically intersecting diamond-coated grooves that optimize coolant flow and interrupt the grinding process up to 7 times per rotation . This unique geometry significantly reduces heat generation during cutting, protecting tooth structure and surrounding soft tissues while maintaining exceptional cutting speed and control. The result is a smoother, cooler operation that benefits both the clinician and the patient. A scientific study from the Medical University of Innsbruck (published in Stomatologie 2009; 106: 29–34) evaluated diamond burs from multiple manufacturers under rigorously standardised conditions — 200,000 RPM, 50 ml/min cooling, and a 152 g load applied to ceramic blocks. The results were clear: The Busch Cool Diamond (Busch® K) achieved the highest total cutting length of 17.30 mm in the primary test series, significantly outperforming competitors including Diatech, Edenta, Horico, and Komet (p < 0.05). Burs with cooling grooves consistently ranked highest for cutting efficiency and sustained longevity. Although all burs showed a performance decline after the first 10 minutes, Cool Diamond instruments maintained superior performance longer, reducing the frequency of replacements. Key Features Biocompatible gold coating for enhanced safety and long-term durability Innovative cooling grooves for maximum coolant delivery and heat reduction Up to 7x interrupted grinding per rotation for smoother, cooler operation High-quality diamond coating for fast, efficient material removal Superior precision and control with minimal vibrati
