Solid Carbide Metric Thread Milling Cutter (M4–M20) – Extended Reach CNC Thread Mill

  • Full Profile Metric Threading M4–M20

  • Extended Length Design for Deep Hole Threading

  • Cutting Conditions for Various Materials

Product Overview:
This extended solid carbide thread milling cutter is engineered for high-precision machining of internal ISO metric threads ranging from M5×0.8 to M20×2.5. Manufactured from premium tungsten carbide, the tool features a full-profile 60° cutting edge, a long reach body (up to 105mm total length), and multi-flute geometry for superior performance in CNC machining centers.
