100mm Extra Long 60° 3-Tooth Carbide Thread Mills for Steel (TiAlCN Coated)
Maximize your threading efficiency in deep-cavity applications with our Extra Long 3-Tooth Thread Mills. Combining the reach of a 100mm shank with the speed of a 3-tooth design, these tools are engineered to cut threads 3x faster than single-point mills while maintaining the rigidity needed for deep-hole machining in steel and stainless steel.
Product Function
Specifically designed for high-speed internal metric threading in deep recesses. By utilizing a 3-profile cutting head, these tools:
- Reduce Cycle Time: Complete thread profiles significantly faster than single-point tools.
- Deep Hole Access: The 100mm (100L) overall length allows threading in deep molds and complex parts where standard tools cannot reach.
- High Precision: Helical interpolation ensures zero taper and perfect thread fit even at extended lengths.
Product Features
- 3-Tooth High-Speed Design: Features three cutting teeth in a row, allowing for higher feed rates and significantly reduced machining time per hole.
- German Walter Substrate: Manufactured using ultra-fine grain tungsten carbide from Walter (Germany) for maximum tool life and structural stability.
- Advanced TiAlCN Coating: Specialized coating provides superior heat resistance and a low friction coefficient, ideal for:
- Carbon Steel & Alloy Steel
- Stainless Steel & Mold Steel
- Cast Iron & Hardened Materials
- 100L Extra-Long Shank: Optimized for deep-cavity work, reducing the need for tool extensions or custom long-reach tooling.

Recommended Cutting Parameters (RPM/Feed)
Attention: When using 100L extra-long tools, minimize runout and adjust parameters for stability.
Workpiece Material | Cutting Speed (Vc: m/min) | Feed per Tooth (fz: mm/t) |
|---|---|---|
Carbon Steel (Soft) | 110 - 150 | 0.02 - 0.05 |
Alloy Steel / Mold Steel | 70 - 110 | 0.015 - 0.04 |
Stainless Steel (304/316) | 60 - 90 | 0.01 - 0.03 |
Cast Iron | 90 - 130 | 0.025 - 0.06 |
Technical Tip: For 100L shanks, we recommend a 2-3 pass strategy for the best thread finish and to avoid tool deflection.

FAQ
Q: Can one 3-tooth mill cut different pitches?
A: No. 3-tooth mills have a fixed pitch (e.g., M6x1.0). You must match the tool to the specific thread pitch. For pitch versatility, please see our Single Point series.
Q: Is the 100L shank prone to vibration?
A: Due to the high-quality German Walter substrate, our tools are very rigid. However, we recommend using high-precision holders and reducing feed rates by 20% compared to standard length tools if vibration occurs.
Q: Does this work on hardened steel?
A: Yes, the TiAlCN coating allows for effective machining of materials up to HRC 50.
Q: Do you provide G-Code for 3-tooth milling?
A: Yes, our technical team can provide programming support for most CNC controllers (Fanuc, Haas, Siemens).
