Unique flute geometry allows the “Viper” to cut faster and longer than other compression spirals on the market today. 

Cut Diameter: 1/2"

Shank: 1/2"

Cut Length: 1 3/8"

Overall Length: 3 1/2"

Flute Type: Compression

Compression means the upcut and downcut spiral flutes compress the material being cut preventing chipping or fuzzing on the top and bottom of the cut. Our unique flute geometry allows the “Viper” to cut faster and longer than other compression spirals on the market today. It also allows for extended sharpening life with excellent performance throughout the tool’s useful life. Compression spirals are used extensively for cutting double-sided laminates (melamine, vinyl, high pressure laminates, painted board, etc.). This series of compression spirals is not recommended for cutting materials thinner than 5/8”.
