Coltene Crown Cutter Bur

Coltene Crown Cutter Bur

The Coltene Crown Cutter Bur is a new-generation monoblock tungsten carbide cutter engineered with advanced technology for rapid and efficient crown reduction. Its precision, computer-designed flute geometry delivers smoother cutting action while significantly reducing vibration and chatter.

Manufactured using computer-aided design and multi-axial grinding processes, this premium carbide bur features optimized angulations, flute depths, rake angles, and blading. The result is superior concentricity, longer cutting life, and reduced chair time during crown removal and preparation procedures.

Features :
