Typhoon carbide tapers. 5/16" head dia. x 1/2" head length, blue fine grit, 1/8" shank
Typhoons have unique structurally aligned points that are ideal for rapid and aggressive shaping and roughing out work on hard and soft wood, acrylic, die stone, plaster, hard rubber and fiberglass. Typhoon burs last longer and do not load as quickly. Coarse (red) grit are more aggressive than fine (blue) grit, but both will remove a lot of material quickly.
