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 micro mills.  Miniature carbide end mills are available in square end, ball end and corner radius geometries.

The turning insert is tipped a PCD layer on one corner of the insert, it's a very good way to achieve high precision cutting with an economical cost saving. The PCD grade TCD 100 is developed by ToolingBox  specially for aluminum alloy (Si<13%) and non-metal finishing turning , wood plank cutting off, which has the ultrafine particle size  of 1um, good impact and abrasion resistance, its sharp edge is very suitable for finishing and cutting off.
