Uncoated Carbide End Mills Arc Premium Uncoated end mills are specially ground for milling aluminium. Sharper cutting edges are possible with uncoated end mills. Also, where indicated, the higher helix angle of 45° helps to evacuate the chips quickly thus reducing the amount of heat generated and producing a good surface finish. Arc Premium Uncoated end mills are ideal for machining aluminium, brass, plastics and other non-ferrous materials. Click for more...

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).

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.

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.

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.

In fact Balzers Balinit® Futura Nano not only out-performs uncoated cutters, TiN and TiCN coated cutters but also many other TiAlN coated cutters as well.

Sharper cutting edges are possible with uncoated end mills and these are recommended for machining aluminium, brass, plastics and other non-ferrous materials.

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

I have this 2", 10-tooth face mill I purchased from McMaster-Carr (https://www.mcmaster.com/3040A14/). I have no information about the suggested SFM, RPM, or feed per tooth from the manufacturer to use with 6061 Aluminum. I'm new to machining, so any help with some generic values for this type of bit would be very helpful.

The ARC Premium branded range of end mills are made from a traceable grade of material. They are precision manufactured for consistency, quality and accuracy.
