Tungsten Carbide End Mills with 4 Flutes ALTiN Coating for High Cutting Temperature​

Discription:
Four flute square end mills with straight flutes are single ended, have four cuttting edges, and have a zero degree helix. They are used to mill plastics, composites of epoxy and glass, and are also used for special profile milling applications. The straight flute minimizes the fraying of the edges and provides better surface finishes than general purpose end mills.
An End Mill’s end cut type can either be center cutting or non-center cutting. Center-cutting end mills can create three-dimensional shapes and profiles, and make plunge cuts similar to a drill bit. All Carbide End Mills are center cutting. Non-center-cutting End Mills are suitable for peripheral milling and finishing, but cannot be used to make plunge cuts. Tungsten Carbide End Mills will specify if they are center or non-center cutting.

Coating:

TiAIN

A special multilayer coating for edge retention and corrosion resistance when used on a wide range of materials including iron based, hardened steels, and stainless steels. Typically TiAIN is used in applications with lower cutting speeds than TiSiN and ALTiN but often improves the tool's lifetime by a factor of three or more.

ALTiN

A general purpose coating that offers improved wear resistance to abrasive, adhesive, or difficult to machine materials such as cast iron, aluminum alloys, steels, copper and more. This is a common used substitute when the advantages of TiAIN cannot be used, as in applications that cannot generate the speeds and feeds required for higher cutting temperatures. ALTiN is harder and more impact resistant than TiAIN and can improve tool life.

TiSiN

This is a high performance coating for milling, tapping and drilling in stainless steels, carbon steels, alloy steels, and cast iron. This coating is extremely heat resistant and can be used with or without coolant. It is exceptional in difficult to machine materials where adhesive wear is particularly high and can be run at much higher speeds and feeds than all other coatings.
