Best 4 flute End Mills

YG-1 E5065 Carbide Square Nose End Mill, Extra Long Reach, Uncoated (Bright) Finish, 30 Deg Helix, 4 Flutes, 3\ Overall Length, 0.125\ Cutting Diameter, 0.125\ Shank Diameter

Suitable for general-purpose machining on hardened and high-alloy steel, steel casting, malleable cast iron, chromium-nickel steel, brass, copper, aluminum with a high percentage of silicon, and abrasive plastic.
Extra-long-length end mills have longer cutting edges and can make deeper cuts than long-length end mills.
Four flutes produce a better finish than fewer flutes.
Carbide can run at higher speeds than high-speed or cobalt steel, resisting wear and high cutting temperatures.
Uncoated (bright) tools have no additional surface treatment or coating for use on a broad range of materials.

Package Contents ---- 8pcs 1/4” end mills, each is individually packed in a plastic storage box..

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.

fewer flutes have more chip-carrying capacity and more flutes produce a finer finish.
Cobalt steel resists abrasion and high cutting temperatures, and has higher feed rates than high-speed steel.
Uncoated (bright) tools have no additional surface treatment or coating for use on a broad range of materials.
Square nose end mills (also called square end) create sharp, unrounded cuts.
Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling.
