Choosing Between the Sub-Miniature & Sub-Miniature
The 3215SM Sub-Miniature is a 2-flute, general-purpose end mill designed to provide greater chip clearance at subminiature diameters. It offers the same ball and square end styles and tight cutter tolerance as its 4-flute counterpart. For applications where added rigidity and finish quality are the priority, consider the 3200SM Sub-Miniature. Its 4-flute design provides more cutting edges at the same small scale.
