Square Cut Style End Mills are the most common type of end mill. They are designed to mill square slots, pockets, and edges. Single end mills have one cutting end, while double end mills have two cutting ends, doubling the life of the tool. Most of our end mills are also available with a Titanium Nitride (TiN) Coating for working in harder material and for longer production runs. They are more resistant to wear than uncoated end mills. Other coatings are available where indicated.
2 FLUTE
Using two flutes allows for maximum chip ejection. All our high speed steel 2 flute end mills are center cutting.
Long flute style end mills are used when a deeper cut or longer reach is required to mill slots or pockets.
Extra flute style end mills are used when an even deeper cut than long flutes can produce is required.
Extra length style end mills are used when an extra deep cut or extra long reach is required.
KEYWAY TOLERANCE
Keyway Tolerance End Mills are commonly used to make keyways in rotary shafts, these end mills have a -0.0015" to 0.0000" mill diameter tolerance for creating a precise fit.
ALUMINUM CUTTING
2 Flute Aluminum Cutting End Mills ae designed with a higher helix angle, these end mills clear more chips and generate less heat, making them ideal for milling softer materials, such as aluminum, brass and bronze. Also available in Zirconium Nitride (ZrN) Coating to minimize packing of chips in the flutes and for very fast removal of material. Zirconium nitride can be subjected to higher operating temperatures and is an ideal coating for aluminum cutting end mills.
3 FLUTE
Three flutes remove more material per revolution than two flute end mills. They track straighter, mill at very high feed rates, and create a smoother finish than 2 flute end mills.

4 FLUTE
Using four flutes provides a finer finish than two flutes and operates with less vibration when run at high speeds. 4 flute end mills are center cutting except where indicated.
