Ball nose spiral end mills are used for smooth contouring and fine detail passes with a CNC router and often for complex shapes like 3D carvings. The rounded ends produce smooth curves that would be impossible to achieve with flat end bits. Small diameter ball nose end mills are used for projects with intricate detail while larger bits are used for smoother projects with more gradual slopes. These bits are also excellent for routing fluted columns and channels in cutting boards and countertops edges.

The radius defines the size of the tip of the bit which is half the size of the cutting diameter. Choose the radius that matches the detail resolution of your project. These ball nose end mill bits come in a wide array of shank and radius combinations, with many different ball nose cutter sizes.
