M2×0.4 Solid Carbide Thread Milling Cutters Three Tri Form Metric Coated Blind Holemaking Threading Tapping High-Stress Fastening Heavy Loads End Mills for Hardened Steels

Why Machinists Choose This Thread Mill: 1 High-Accuracy Threading – Maintains tight tolerance for flawless metric threads. 2. Left-Hand Spiral Design – Optimized for climb milling, reducing deflection and improving finish. 3. Tri-Form Cutting Edge – Three-form geometry minimizes tool pressure, preventing chatter and burrs. 4. Internal & External Threading – One tool for both holemaking and external threading applications. 5. H6 Shank Tolerance – Ensures perfect concentricity in high-precision CNC holders.

• Versatile Threading Performance:solid carbide thread mills work well for internal and external thread milling. They cut many materials like alloy steels, hardened steels (up to 55 HRC), stainless steels, titanium, cast iron, and tool steels. They handle high-speed thread milling easily and are good for tough jobs in aerospace, automotive, medical, and mold/die work.
• High Precision and Stability:The h6 shank fits tightly in precision tool holders, so these carbide thread milling cutters stay steady during cuts. They make accurate 60° internal threads and can cut larger threads with the same pitch. Cutting at the first thread keeps threads straight and reduces chatter, even in hard metals.
• Efficient Thread Machining:The three-form helical flute design lowers cutting pressure, so these hardened thread mills last longer and finish smoother. They work for small micro thread mills and big threads, keeping cuts stable and clean.
• Built to Last:Made from tough tungsten carbide and coated with nano layers, these tools handle heat and wear well. They run longer in dry or wet conditions and stay sharp in heavy cutting, keeping high precision without breaking down.
