Fissure Bur

This rightward-cutting, left-spiral fissure burs are intended for use in the rough cutting or trimming of hard thermoforming foils and plates. They are standalone replacement burs identical to the fissure burs included with the Erkodent Trimming and Polishing Kit. Use with caution at high revolutions (20,000 – 40,000 rpm). Always wear protective eyewear during use.
