Choosing Between the Sub-Miniature & Sub-Miniature
The 3200SM Sub-Miniature is a 4-flute, general-purpose end mill designed for small-diameter machining in titanium, super alloys, hardened steels, steels, cast iron, brass, copper, and low-silicon aluminum. Its 4-flute geometry provides added rigidity and supports consistent finish quality at subminiature sizes. For applications that require greater chip clearance, consider the 3215SM Sub-Miniature. Its 2-flute design provides more room for chip evacuation while offering the same ball and square end styles and subminiature cutter tolerance.
