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 Applications

The cool diamant cylinder diamond dental bur is well-suited for two primary procedural categories:

• Crown Preparation — achieving precise axial walls and optimal finish lines for full-coverage restorations
• Cavity/Fissure Preparation — accurate removal of carious tissue and preparation of fissure morphology prior to restoration

The cylinder round geometry provides uniform lateral cutting action, making it a reliable choice when consistent depth and wall parallelism are required. As part of the Cool Diamant range, this cool diamant cylinder diamond dental bur is engineered to support efficient cutting while maintaining instrument integrity over repeated clinical use.

German Quality Manufacturing

Busch & Co. GmbH has a longstanding reputation for precision rotary instrument production. Each cool diamant cylinder diamond dental bur in this pack is produced in Germany, reflecting the quality control and manufacturing expertise that the brand is known for worldwide.

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.
