At Deutsche Dental Technologien, we supply top-tier Busch Burs. In the Busch Bur collection, the Busch Cool Diamond Burs are standout performers when it comes to durability, efficiency, and clinical longevity.
Independent Research on Diamond Bur Longevity: The 2009 Innsbruck Study
A rigorous scientific study published in Stomatologie (2009; 106: 29–34) by researchers from the Medical University of Innsbruck tested the cutting efficiency and standfestigkeit (durability / service life) of diamond burs from leading manufacturers under standardized conditions.

Study Parameters:
- High-speed handpiece: 200,000 RPM
- Constant 50 ml/min water spray cooling
- 152 g load
- Standardized 99.5% aluminum oxide ceramic test blocks
- Four 10-minute cuts (40 minutes total continuous use)
- Multiple burs tested per type (ISO 12 and ISO 16, 105–125 µm grit)
Key Findings: Busch Cool Diamond Burs Excel in Longevity
The Busch Cool Diamond Schleifer (Busch® K) with its signature cooling grooves (Kühlrillen) delivered the best overall performance in the primary test series:
- Total cutting length: 17.30 mm — significantly higher than Diatech, Edenta, Horico, Komet, and others (p < 0.05)
- Burs with cooling grooves consistently ranked at the top for both cutting efficiency and sustained performance
- All diamond burs experienced a sharp drop after the first 10 minutes, but instruments with cooling grooves maintained superior performance longer and required less frequent replacement
Why cooling grooves make them the longest lasting diamond burs:
- Superior coolant delivery and heat dissipation
- Better evacuation of debris (prevents clogging)
- Reduced heat buildup → less wear on diamonds and binder
- Extended usable life in clinical practice
Why Longevity Matters for Your Practice
- Cost savings — fewer burs per procedure
- Consistent cutting performance throughout the critical early phase
- Better patient comfort — reduced vibration and heat
- Predictable results in crown preps, cavity preparations, and restorative work
Dentists and lab technicians who demand the longest lasting diamond burs choose instruments that are engineered for real-world durability, not just initial sharpness.
