Drill Bits - carbide drill bits

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.

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

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

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).

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).

High speed steel drill bits, also known as HSS drill bits, are incredibly durable and well suited for drilling into metal surfaces because they are significantly more heat resistant than conventional drill bits. While the spirals clear the hole of dirt, the front edges cut the material. When utilising smaller pieces, use light pressure to keep them from breaking. HSS drill bits can also be used to drill through plastic and wood.

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.

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.

The Balzers Balinit® Futura Nano coating offers outstanding properties enabling high-performance machining and long tool life.

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.

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...
