Amana tool 46045 Solid Carbide Spiral 3/8 Dia x 7/8 Cut Height x 3/8 Shank x 2-1/2 Inch Long Composite, Fiberglass & Phenolic Cutting ZrN Coated 2 Flute Up-Cut Router Bit

Amana Tool’s Modern Materials Finishing Geometry (MMFG) incorporates high shear, multi-fluting and Zirconium Nitride (ZrN) coating designed for the ultimate combination of finish and tool longevity in aerospace materials. Modern-day materials present challenges to the fabricator, using Amana Tool’s special, multi-flute edge tool featuring ZrN ceramic coating, addresses these challenges with a winning geometry combination.
