3100L Series. Two Flute Left Hand Compression Spiral
LEFT HAND ROTATION. By using both right and left hand rotations, users can climb cut in either direction and control "blow out" on entrance and exit cuts. Compression spiral means that 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 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. (m) = 1/4" upcut length.
