These router bits are made with an extra-long reduced shank section for deeper reach and better chip clearance. Amana Tool®'s Modern Materials Finishing Geometry (MMFG) incorporates high shear, multi-flute and ZrN coating designed for the ultimate combination of finish and tool longevity in aerospace materials

Spiral-flute bits combine a shearing action in cutting with an augering action in chip clearance. The shearing action yields an especially clean accurate cut while the augering action clears chips from the cut. The ‘Up-Cut’ shears from the bottom up pulling chips from the bottom up thus allowing deeper penetration with less stress on the tool. An excellent choice for mortising.

Designed to combine the fast free cutting of O flute geometry with the tool life available from solid carbide particularly in small diameters.
