3-flute UN thread milling cutter

Key Advantages of UNC/UNF Thread Mills:

Strong Standard Compatibility: Strictly conforms to the Unified National Thread (UN) standard, ensuring seamless integration with mainstream North American equipment and high irreplaceability.
Dual-Spec Coverage: UNC coarse threads offer superior chip evacuation and impact resistance for heavy-duty machining, while UNF fine threads deliver high precision and excellent surface finish for critical assembly applications.
Optimized Structural Design: Three-flute staggered layout (15° for coarse / 8° for fine) combined with a precise 60° ±0.5° thread angle achieves up to 40% faster feed rates without compromising thread quality.
Reliable Material & Craftsmanship: Solid carbide construction with application-specific tooth profiles (larger tooth height and deeper flutes for coarse threads / fine, dense geometry for fine threads) balances high-efficiency cutting with extended tool life.
