Atlas Cutting Tools stock an extensive range of over 15,000 Standard, Carbide, Cobalt and High Speed End Mills all USA manufactured to the highest standard. Our End Mills are all available with same day shipping at affordable prices.

An End Mill is a type of milling cutter designed to be held by the shank on one end in order for it to cut with the opposite end. The advantage to an End Mill is that, unlike any other type of milling cutter, it is capable of cutting on the periphery, the face or the end of the cutter. At Atlas, our offering of End Mills is extensive-ranging from conventional HSS, Cobalt, and Solid Carbide Roughing & Finishing Mills to application and material specific tools employing the latest geometries and coating technologies all resulting in improved efficiency and productivity for you. The number of flutes can range from two to eight. The fewer flutes offer the most efficient chip removal, but a higher amount of flutes provide a smoother finish. The End Mill’s helix angle is also important. Most general purpose End Mills have a 30-degree helix angle because it is halfway between “slow” (low-angle) and “fast” (high-angle) helix End Mills.

Specific projects require special styles of End Mills. Ball Nose End Mills are best for machining round bottom holes and complex contoured surfaces. Square Nose End Mills have square ends and are best for slotting, profiling, and roughing. Corner Radius End Mills have a square end with rounded corners on the cutting edges to reduce chipping. Double-ended End Mills have the same cutting edges and styles on both ends, doubling the tool’s life compared to Single-ended End Mills.

Cutter material is an important consideration when selecting an end mill. Carbide End Mills can run at higher speeds than high-speed or cobalt steel, it is also more resistant to wear and can be used at high cutting temperatures. Cobalt Steel End Mills resists abrasion and high cutting temperatures, and has higher feed rates than High-speed Steel. High-speed Steel End Mills are compatible with a variety of materials and is typically used for less demanding jobs.

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. HSS and Cobalt End Mills will specify if they are center or non-center cutting. 

Atlas Cutting Tools end mills offer a variety of coatings. Some end mills are uncoated, while others are coated with finishes to enhance performance. Most finishes extend the life of the End Mill and allow higher cutting speeds and feed rates. 

Atlas Cutting Tools End Mill Coatings:

TiN (Titanium Nitride) End Mill Coating

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 TiN is used in applications with lower cutting speeds than TiCN and ALTiN but often improves the tool's lifetime by a factor of three or more.

TiCN (Titanium Carbonitride) End Mill Coating

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 ALTiN cannot be used, as in applications that cannot generate the speeds and feeds required for higher cutting temperatures. TiCN is harder and more impact resistant than TiN and can improve tool life by as much as 800%.

ALTiN (Aluminum Titanium Nitride) End Mill Coating

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.
