60° 3-Tooth Solid Carbide Thread Mills for Steel & Stainless Steel (TiAlCN Coated)
Upgrade your high-speed CNC threading operations with our premium 60° 3-Tooth Solid Carbide Thread Mills. Specially engineered for steel, stainless steel, cast iron, and high-temp alloys, the 3-tooth design strikes the perfect balance between rapid machining speed and low cutting torque, providing superior thread quality without the risk of tool deflection.
Product Function
Designed for high-efficiency internal metric threading (both Coarse and Fine threads), these 3-tooth thread mills perform helical interpolation to cut threads in a fraction of the time required by single-point tools.
- High-Speed Threading: Completes full thread profiles in fewer helical orbits compared to single-point mills.
- Low-Vibration Cut: Generates significantly lower cutting forces than full-form thread mills, eliminating taper and chatter in deep or tough hole applications.
Product Features
- German Walter Substrate: Built on premium ultra-micro grain tungsten carbide manufactured by Walter (Germany), delivering exceptional toughness and wear resistance.
- Specialized TiAlCN Coating: High-hardness Titanium Aluminum Carbonitride coating provides superior thermal protection and low friction coefficient—specifically optimized for:
- Carbon Steel & Alloy Steel
- Stainless Steel (304, 316)
- Cast Iron
- Mold Steel (up to HRC 55)
- Titanium Alloys & Nickel Alloys
- Dual Thread Profiles Available: Full range covering both Coarse Threads (M1.0 to M24) and Fine Threads (M4.0 to M20).
- High Rigidity Structure: Sturdy shank diameters (D4 to D16) and optimized flute geometry (3F/4F) ensure maximum tool strength and smooth chip evacuation.

Client Benefits
- 3X Faster Processing: Drastically reduces cycle time compared to single-point thread mills while keeping total cutting resistance manageable.
- No Deflection or Taper: Unlike full-profile thread mills that engage the entire thread length at once, the 3-tooth design reduces load, preventing tool deflection in deep holes.
- Extended Tool Life: German Walter tungsten carbide substrate combined with TiAlCN coating ensures exceptional heat resistance and edge retention.
- Zero-Scrap Safety: If a thread mill wears out or breaks, it can be removed easily without ruining expensive workpieces (unlike broken taps).
FAQ
Q: How does a 3-tooth thread mill differ from a single-point thread mill?
A: A single-point thread mill has 1 teeth profile along the axial direction and cuts one pitch per pass, making it pitch-universal but slower. A 3-tooth thread mill has 3 teeth forms in a line, cutting threads much faster while maintaining low tool pressure.
Q: Can a 3-tooth thread mill cut different pitches?
A: No. Because the 3 teeth are ground to a specific pitch distance (e.g., 1.5mm), each model is dedicated to its matching pitch. However, it can cut both right-hand and left-hand threads of that specific pitch.
Q: Is coolant required when using TiAlCN coated thread mills?
A: Water-soluble coolant or neat oil mist is recommended when machining steel and stainless steel to flush chips efficiently and prolong tool life.
Q: Do you offer G-code programming assistance for thread milling?
A: Yes! Our technical sales engineers can provide helical interpolation macro programs tailored to your machine controller (Fanuc, Siemens, Heidenhain, Haas).
