M3 - M20 Carbide Thread Mills High Speed Milling Bits For Steel

3 Thread Carbide Thread Mill for Steel/Stainless/Titanium High Speed CNC Thread Milling M3-M20

Introduction:

Our 3-thread carbide thread mill is engineered for high-performance internal and external threading in steel (HRC 45+), stainless steel, and titanium alloys. Featuring a precision-ground solid carbide design and optimized flute geometry, this tool delivers superior thread quality (ISO 2B/3B class) while reducing cycle times by up to 60% compared to taps. Ideal for CNC machining centers, Swiss-type lathes, and high-volume production.

Features:

✔ 3-Thread Design – Balances chip evacuation and tool rigidity
✔ Solid Carbide Construction – 5X longer life than HSS thread mills
✔ TiAlN/AlCrN Coating – Optional for heat/friction reduction (800°C resistant)
✔ Full & Partial Profile Options – For blind holes and through holes
✔ Precision Ground – ±0.01mm tolerance, <0.005mm runout
✔ Size Range – M3 to M20 (custom UN/UNC/UNF threads available)

Advantages:

✅ 60% Faster – Than traditional tapping (up to 30 m/min cutting speed)
✅ Burr-Free Threads – Sharp edges for clean ISO-class threads
✅ Reduced Machine Load – Lower torque vs. taps (prevents breakage)
✅ Versatile – Cuts left-hand & right-hand threads
✅ Through-Coolant Ready – Optional internal coolant channels
