About MIRB 65 R0.20xD4x0.4x50-2 flute

MIRB R0.20xD4x0.8x50-2F Micro Ball Nose End Mill is a high-precision solid carbide cutting tool designed for fine finishing and micro milling applications in hardened materials up to 65 HRC. Manufactured from premium sub-micron carbide rod with advanced coating, this tool provides excellent wear resistance, high heat stability, and superior cutting performance during high-speed CNC machining.

With a 0.20 mm radius ball nose and 2-flute geometry, the tool is ideal for intricate profiling, small radius machining, and detailed contour milling in die & mould components, precision parts, and aerospace applications. The micro cutting edge ensures smooth surface finish while maintaining dimensional accuracy even in hardened steels such as D2, H13, SKD11, and other high hardness tool steels.

The optimized flute design and rigid shank diameter of 4 mm provide excellent stability and reduced vibration during machining, allowing consistent performance in micro milling operations. It is widely used for fine finishing of deep cavities, engraving, micro slotting, and 3D contour machining on CNC milling machines.

This micro ball nose cutter is suitable for industries such as die & mould manufacturing, precision engineering, aerospace components, and medical parts machining where high accuracy and fine surface finish are critical.
