PRODUCT DETAILS

GM Series Carbide Micro Ball Nose End Mill (2 Flutes) is designed for precision micro machining and 3D contour milling of small, intricate components. Its micro ball nose geometry ensures smooth cutting and accurate contouring, making it ideal for fine surface finishing in molds, dies, and precision parts.

Made from ultra-fine grain carbide, this tool provides excellent rigidity, wear resistance, and dimensional accuracy when machining steels up to HRC 40, including mild steel, pre-hardened mold steel, and medium carbon steel. The 2-flute design enhances chip evacuation and minimizes cutting resistance, ensuring stable performance during high-speed CNC operations.

With its superior geometry and precision-ground edges, the GM Series delivers consistent surface quality and extended tool life — even in demanding micro milling applications.


Key Features:

  • Ultra-Fine Grain Carbide Substrate
    Built from premium micro-grain tungsten carbide for maximum hardness and wear resistance, even under high-speed, high-load conditions.

  • Optimized Ball Nose Geometry
    Delivers smooth contouring and 3D profiling for detailed mold cavities, electrodes, and intricate steel features.

  • Tight Tolerance Control
    Manufactured with strict diameter tolerance and roundness for stable cutting, essential in micro-diameter operations.

  • High Performance on Hardened Steel
    Performs exceptionally well on tool steel, alloy steel, and pre-hardened molds (up to HRC 55–60), reducing the need for tool changes and rework.

  • Nano Coating Optional
    Optional nano or TiSiN Coating improves heat resistance and extends tool life in dry or semi-dry machining setups.


Ideal For:

  • Precision mold and die making

  • Micro component manufacturing

  • Medical and electronic part machining

  • 3D contour cutting on steel materials
