Miniature or Micro End Mills

Micro or miniature end mills are small diameter end mills with an 1/8" or 3mm shank diameter, where the cutting diameter is usually smaller.  They are true mini end mills!  These bits come in diameters from .005" to .120".  They also come in standard lengths of 1-1/2" OAL and extended lengths of 2-1/2" OAL.  Mini cutting tools are generally used on CNC machines for a variety of milling operations like milling molds, drilling, profiling, and engraving.  The printed circuit board industry uses a wide variety of PCB mills.  Miniature carbide end mills are available in square end, ball end and corner radius geometries.
