Cryo-Thunderburr 1/2" Dia. 5PC set in Metal Index

At first glance, Cryo-Thunderburrs look like ordinary burrs, but look closer. Cryo-Thunderburrs incorporate an alternating series of coarse-cut teeth and fine-cut teeth. This patented design is simple yet revolutionary. The coarse teeth promote faster cutting and the finer teeth improve the surface finish, and the combination reduces chatter.
• Coarse and Fine Teeth - Faster cut, smoother finish, less chatter
• Cryophase™ Treated - maximum life and improved durability
