Precision Thread Milling Tools for CNC Machining
Our thread milling tool machines internal/external threads on holes or shafts via helical milling. Unlike taps, it excels in blind holes, interrupted threads, and oversized diameters. Compatible with steel, stainless steel, and titanium alloys, it delivers superior precision, extended tool life, and flexibility across ISO, UN, and NPT standards.
Why Choose Our Thread Milling Tools?
1. Enhanced Rigidity & Longer Lifespan
- Solid carbide + anti-vibration design reduces chatter, extending tool life by 50%+ vs. taps.
2. One Tool, Multiple Applications
- Cut M3-M24 metric/imperial threads with one tool. Adjust CNC programs for pitch variations—reduce inventory costs by 70%.
3. Optimized Cutting Performance
- Helical flutes + TiAlN nano-coating enable:
30% faster wet/dry machining
900°C+ heat resistance (stainless steel/titanium)
Mirror finishes (Ra ≤0.8μm), eliminating polishing
4. Master Complex Threads
- Solutions for blind holes, deep threads, thin walls, and interrupted cuts:
90% lower breakage (distributed cutting forces)
Stable 1:5 overhang machining
5. End-to-End Support
- Kits for coarse/fine/left-hand threads include:
ISO/UN/NPT-compliant inserts
Free custom cutting parameter services

Selection Guide
Material-Specific Tools:
- Steel/Cast Iron: TiAlN-coated carbide for heat/wear resistance.
- Stainless Steel: PVD coating + polished edges (prevents buildup).
- Aluminum: Uncoated polished tools (avoids chip adhesion).
- Titanium: Ultra-fine carbide + AlCrN coating.
Thread Standards & Depth:
- Confirm ISO/UN/NPT; match inserts.
- Coarse threads: 4-6 flutes (chip clearance).
- Fine threads: 8-10 flutes (Ra <0.8μm).
- Deep holes (>5×D): Use peck milling (G73).

Our company specializes in manufacturing and customizing a wide array of cutting tools, dedicated to boosting clients' production efficiency and slashing manufacturing costs. We offer comprehensive tool solutions tailored for various cutting materials, encompassing carbon steel (approx. HB225 hardness), alloy steel (HB225~325 hardness), pre-hardened steel (up to HRC45 hardness), quenched steel (HRC40~61 hardness), and cast iron. These solutions cater to diverse cutting needs, including straight cuts, curved cuts, L-shaped cuts, groove cuts, internal arc cuts, external arc cuts, T-shaped cuts, drilling, and threading.
Our carbide cutting tools excel in processing the aforementioned steel types, delivering exceptional performance with a precision tolerance of just ±0.02mm. This ensures that our customers can effortlessly achieve professional-grade cutting quality, making us your ideal partner for milling tool solutions.
We can provide customized OEM production services. If our standard carbide milling cutters do not meet your requirements, you can customize the diameter within 0.2mm-25mm, the total length from 50mm to 200mm, and choose flutes of 4F, 5F, 6F, or 8F. You can also add your own logo. Please feel free to contact us for any needs.
