1/4 x 2 1/2” Solid Carbide Flat (Square) center cutting 3 Flute End Mill with a .250 (1/4″) cutting tip and a 1 inch length of cut.
This tool features a 45 degree helix which makes it ideal for finishing due to its high shear angle and cutting aggressiveness. 3 Flute end mills are perfect for milling aluminum and other non-ferrous materials, they also tend to reduce vibrations during the milling operation.
These tools are coated with a proprietary high performance *Astra coating* that allows higher speed & feed rates as well as extended tool life & increased lubricity in abrasive material. Made in the USA

I have not used this bit for any long jobs yet but in the first short jobs I have used it for it has preformed very well! It is fast cutting and the flutes stay clean and free of chips.
