Amana Tool 51620 3/16" Solid Carbide ZrN Coated End Mill Up-Cut Router Bit

Designed to route a finished appearance into aluminum, brass, copper and non-ferrous metals in one pass, these Amana Tool end mills utilize the ‘O’ flute up-cut design for a super-clean finish. By combining the up-cut design along with the common 3/32 inch convex radius, you can maximize your efficiency by routing one single pass. The Zirconium Nitride (ZrN) coating creates a harder and tougher cutting ceramic over carbide edge allowing for a prolonged cutting edge life and helps to prevent the build-up/galling of material in the flutes while cutting. Amana’s combination end mill/router bits offer the flexibility to cut the radius along with the proven performance of the up-cut design for superior chip ejection.
