1/4 x 2 1/2” Solid Carbide Ball Nose 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 soft metals, 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.
What is a Ball Nose End Mill?
Ball nose end mills, also known as full radius end mills or ball mills, are cutting tools where the nose radius is equal to half of the diameter of the tool. This creates a constant single radius (or ball) at the tool end with no straight edge (sharp corners) in the profile. They are used for contour milling, shallow slotting, pocketing and contouring applications. Ball nose mills are ideal for 3D contouring because they are less prone to chipping and leave a nice rounded edge.
Tip: Use a Roughing end mill first to remove large areas of material then proceed with a ball nose end mill.
