Corner radius end mills have cutting edges with rounded corners to reduce chipping and provide longer tool life.
Four flutes produce a better finish than fewer flutes.
Carbide can run at higher speeds than high-speed steel, resisting abrasion and high cutting temperatures.
Titanium aluminum nitride (TiAlN) coating lubricates the end mill for high-temperature stability and abrasion resistance at high cutting speeds.
Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling.
