Instrument Dimensions

Per ISO 6360, the size number is the maximum head diameter in tenths of a millimeter. See our Busch Bur Size Chart for the full size conversion table, shank codes, and color ring guide.

Clinical Benefits

Clinicians who demand precision will appreciate the thermal management qualities built into this diamond dental bur taper (cone) rounded edge design. By minimizing heat buildup at the cutting interface, the Cool Diamant series supports pulpal health and reduces patient discomfort during extended preparation procedures. The friction grip shank ensures a secure, vibration-minimized connection with compatible high-speed handpieces, further enhancing operator control and margin accuracy.

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.
