3 Flutes Nano Blue Coated Aluminum End Mill
CNC milling of aluminum can be difficult, because the material can stick to the flutes and the chips can pack. Today's high performance end mill bits for aluminum have large flutes to yield the maximum metal removal rates possible. They also feature eccentric grinding on the outside diameters of the bits to give them strength and stability. Aluminum milling bits are available in square end, ball end, corner radius, and roughing end mill geometries.

Requirements for Efficient Machining of Aluminum
Due to the soft and “sticky” nature of aluminum, specific geometries and characteristics of a carbide end mill are required for efficient machining. Many cutting tool manufacturers offer end mills specifically designed for aluminum for this reason.
A sharp edge and high rake angles are needed to separate a chip from the parent material. Positive rake angles up to 25 degrees radial and 20 degrees axial are common.
A high helix angle, generally around 45 degrees is also desirable. The helix helps move chips up and out of the cutting zone and also generates an excellent surface finish. The angle also helps soften the impact at entrance of cut, resulting in a smoother, quieter cut.
For aluminum milling a two- or three-flute end mill works best because this allows for larger flute areas. A core diameter of slightly less than 50 percent of cutter diameter is optimum for the same reason. An open flute design is essential for easy chip movement away from the cutting zone. Surface finish on the flute is also critical. Long-chipping, low silicon aluminum alloys have a tendency to stick to cutting tools. As a heated chip flows over the flute it will try to adhere to the tool surface. The flute surface must be very smooth to counteract this tendency.
3 Flute End Mills - Carbide
Three flute end mills are used for higher feed rates than two flute end mills, and are often used in aluminum machining. They are commonly used in grooving operations where the chip is crowded. They are also used in non-ferrous milling applications where high feed rates are used. Three flute mills tend to reduce vibrations during the cutting operation.
