The Cargo Threading Tool is a precision thread cutting tool holder for CNC lathes and conventional lathes used to machine accurate internal and external threads on shafts, bolts, housings, nuts, and other threaded components. It’s engineered to securely hold threading inserts with various profile standards (ISO metric, UN, BSP, Whitworth, NPT, etc.) and provides stable cutting performance, excellent chip control, and precise thread geometry. Threading tools are essential for creating consistent, high-quality threads in industrial turning operations.

Technical Specifications

Product Variants & Dimensions 

Threading holders typically follow ISO tooling standards with various shank sizes and insert compatibility:

Note: Specific Cargo threading tool variants may vary in shank size and compatibility. Inserts must match your thread profile and pitch requirement.

Key Features & Benefits

✔ Precision Thread Cutting: Designed to produce clean, accurate threads with consistent profile geometry.
✔ Wide Thread Compatibility: Works with ISO standard threading inserts — external (ER) and internal (IR) — covering metric, UN, BSP, Whitworth, NPT, and other common thread types.
✔ High-Rigidity Tool Body: Hardened steel body minimizes deflection and vibration, leading to smoother threads and longer tool life.
✔ Stable Insert Holding: Screw or clamp system ensures secure insert seating under cutting loads.
✔ Suitable for CNC & Manual Lathes: Reliable performance in both automatic and manual thread turning operations.
✔ Versatile Industrial Applications: Ideal for automotive fasteners, precision components, valve stems, pipe fittings, and threaded housings.

Recommended Threading Inserts 

Choose threading inserts that match the desired thread type and profile, such as:

• 16ER/16IR series – Standard ISO metric/UN external and internal threads

• 22ER/22IR series – For larger diameters and heavier threads

• Full-profile and partial-profile inserts – For different engineering standards (Metric, UN, Whitworth, NPT, etc.)

Using the correct threading insert ensures accurate pitch, reduced cutting forces, and improved surface finish.

Typical Applications

The Cargo Threading Tool is used for:

• External Threading: Creating threads on the outer diameter of components such as shafts, studs, and bolts.

• Internal Threading: Machining threads inside holes such as nuts, sleeves, and couplings.

• Metric & Imperial Threads: Supports a range of thread standards and pitches common in mechanical engineering.

• General Industrial Machining: Widely used across automotive, aerospace, tool & die making, and heavy engineering industries.

Why Choose Cargo Threading Tool?

✔ Superior Thread Accuracy: Designed for precision thread profile control and minimal deviation.
✔ Wide Insert Support: Compatible with widely available carbide threading inserts, reducing tooling costs and lead times.
✔ Industrial-Grade Durability: Hardened solid steel holder withstands vibration and heavy loads.
✔ Versatile Use Cases: Suitable for both CNC and manual lathe threading operations.
✔ Optimized for Productivity: Stable grip on inserts improves thread quality and reduces chatter during cutting.

Frequently Asked Questions (FAQ)

Q1: What is a threading tool?
A threading tool holder is a specialized lathe tool used to cut precise internal and external threads on cylindrical workpieces using carbide threading inserts.

Q2: What types of threads can be cut?
With the right inserts, you can machine metric, UN, BSP, Whitworth, NPT, and other standard thread types.

Q3: Are threading inserts included?
No — threading inserts are sold separately and must match your desired thread profile and pitch.

Q4: Can this tool holder be used on CNC machines?
Yes — it is designed for use on CNC turning centers and conventional lathe machines.

Q5: Why use carbide threading inserts?
Carbide inserts provide wear resistance, high speed capability, and precision thread cutting with minimal rework.
