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

Slow Spiral (Low Helix) Router Bits are designed to lessen the up or down force to help keep chip outs from happening on the top of the material. Great for more brittle substrates.
