This 1.00mm 4-flute solid carbide micro end mill features a square end, center-cutting geometry, and a nitrogen-treated / nitride-coated finish. The short 3mm length of cut helps improve rigidity for precision micro milling, profiling, finishing, and small-detail CNC work.

The 4-flute design is well suited for finishing passes, light profiling, and small-feature machining where a clean flat-bottom cut is needed. The nitrogen-treated / nitride-coated finish helps improve surface hardness and wear resistance compared with a plain bright finish. Because this is a 1.00mm micro end mill, use conservative speeds, feeds, shallow cuts, and a rigid CNC setup, especially when cutting harder or ferrous materials.

  • Tool type: Solid carbide micro end mill

  • Finish / coating: Nitrogen-treated / nitride-coated finish
  • Helix angle: 30°
  • Length of cut: 3mm / 0.118"
  • Shank diameter: 3mm
  • Overall length: 2.00"
  • Cutting type: Center cutting
  • Cutting direction: Right hand
  • Flute direction: Right hand / up cut

Typical Applications

  • Precision CNC micro milling
  • Small-detail profiling and finishing
  • Flat-bottom pocketing and contour work
  • Soft metals and non-ferrous materials
  • Plastics, wax, and fine-detail machining
  • Light-duty ferrous metal work only with proper setup

Benefits

  • 1.00mm cutting diameter is useful for very small features, fine details, and precision micro machining.
  • 4-flute geometry supports smoother finishing and improved edge support in suitable materials.
  • Square-end design is useful for flat-bottom pockets, profiles, and detail cuts.
  • Center-cutting geometry allows ramping and controlled plunge-style entry when used properly.
  • Short 3mm LOC helps improve rigidity compared with longer-reach micro end mills.
  • 3mm shank provides a larger holding diameter than the cutting diameter for improved support.
  • Nitrogen-treated / nitride-coated finish helps improve surface hardness and wear resistance compared with a plain bright finish.
