Solid Carbide Micro End Mills for Precision Milling
Micro end mills are small-diameter carbide milling tools used when the workpiece requires fine slots, narrow pockets, miniature details, small corner features or precision surface finishing. They are also called miniature end mills, small diameter end mills or micro milling cutters.
Because small-diameter tools have lower rigidity than standard end mills, micro milling requires careful control of tool runout, tool holding, flute length, chip evacuation, cutting depth and machine stability. The right micro end mill should match the workpiece material, feature size, reach requirement and finish target.

Micro End Mills FAQ
What are micro end mills?
Micro end mills are small-diameter carbide end mills used for precision CNC milling, small slots, micro pockets, fine details, mold features and miniature parts. They are often selected when standard end mills are too large for the required feature size.
What is the difference between micro end mills and standard end mills?
Micro end mills have much smaller cutting diameters and require better runout control, stable tool holding, suitable cutting parameters and careful chip evacuation. Standard end mills are generally stronger and more tolerant of cutting load.
