Whiteside UD4122M Up/Down Cut Spiral 2+2, 3/8"SH, 3/8"CD, 1-1/4"CL

Whiteside UD4122M Up/Down Cut Spiral 2+2, 3/8"SH, 3/8"CD, 1-1/4"CL works wonderfully with Natural woods, composites, hard plastics, thin aluminum, achieving great results at 16,000-18,000 (max 24,000). Highlights: Made from solid carbide, each bit contains up cut and down cut flutes. This flute design creates a compression cut that prevents fraying and splintering. Compression spirals will save you time and money on finishing your projects edges by reducing sanding time. This bit has the added feature of shorter up cut flutes, allowing the down shear cutting action to the top surface during shallow cuts.
