Meant for heavy loads, this bit is engineered for maximum bit life in high wear applications. Ideal for long production runs in MDF and laminated materials. 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.
