3 Flute Carbide End Mill - Standard Length - TiAlN Coated

Two flute end mills have a larger flute volume and therefore a higher chip carrying capacity. Suitable for higher stock removal rates where finish is not critical.

These are centre cutting end mills enabling the tool to plunge cut in the same way as a traditional slot drill (notice how one cutting edge is longer and passes slightly over the centre line).

Three-flute end mills are often a good compromise between the high flute volume of 2-flute cutters and the greater strength and surface finishes of 4-flute cutters.

Centre Cutting: These are a centre cutting end mills enabling the tool to plunge cut (notice how one cutting edge is longer and passes slightly over the centre line).

The hemispherical end of ball nose end mills make them ideal for machining 3-dimensional contoured shapes.

The end mill cuts a square corner. This is the most common type of end mill.

The helix angle is the angle of the cutting edge on the side of the cutter.

30° Helix: Generallly accepted as the industry standard for rigidity, sharpness and cutting edge strength. Adequate for cutting carbon steel and some tool steels.

40° and 45° Helix: Higher helix angles increase the effective shearing action and because the cutting forces are directed more vertically, tool deflection is reduced. Chip ejection is also improved thus reducing the amount of heat generated.
