Engineered for precision internal threading in hard materials, Carmex MT3 Solid Carbide Fast Type Thread Mills deliver reliable metric threads in M3, M4, and M5 sizes with 0.5 mm pitch. Designed for demanding applications, this tool packs stability and durability for challenging metals and alloys.

• Thread sizes: Metric internal threads in M3, M4, and M5 with 0.5 mm pitch.
• Material: Solid carbide with MT3 shank for high rigidity and long tool life in tough workpieces.
• Coating: MT3 ultra-fine grade with a PVD multi-layer coating for improved heat resistance and wear protection.
• Flute count: Up to 7 flutes on select models to enhance chip evacuation and stability when cutting hard materials.
• Type: Fast Type geometry engineered for efficient material removal and shorter cycle times during thread milling.
• Working range: Capable of machining hard materials up to 65 HRC, including superalloys and hardened steels.

This thread mill delivers precise, repeatable threads in challenging workpieces, with a coating and geometry designed to maintain edge stability under high heat and wear. Its multi-flute design and robust MT3 shank are ideal for production environments where consistent thread quality, reduced cycle times, and reliable performance in hard metals are essential. Perfect for aerospace, automotive, medical device manufacturing, and mold/die applications where hardened substrates and tight tolerances matter.
