NARZYNKA M16 DIN-22568 LH 6g HSSE INOX Threading Die

The M16 DIN-22568 LH 6g HSSE INOX threading die is a professional-grade cutting tool engineered for creating precise external left-hand threads. Constructed from high-speed steel with cobalt alloying, this die offers exceptional heat resistance and structural integrity, making it an ideal choice for demanding industrial metalworking tasks. It adheres to the DIN-22568 standard and meets the 6g tolerance class, ensuring consistent and accurate thread profiles for various mechanical applications.

Advantages

The primary benefit of this threading die is its specialized composition of HSSE cobalt-alloyed steel, which significantly enhances tool life and performance when working with abrasive or work-hardening materials. Its design is specifically optimized for stainless steel, reducing the risk of premature wear and ensuring clean, burr-free threads. The left-hand thread configuration provides versatility for specialized mechanical assemblies, while the robust construction maintains dimensional stability even under high-stress cutting conditions.

Suitable for

• Cutting external left-hand threads on stainless steel components
• Machining difficult-to-cut alloys and high-tensile materials
• Industrial maintenance and repair operations
• Precision manufacturing of threaded fasteners and shafts

When it may not be suitable

This tool is not intended for use on soft materials where standard carbon steel dies would suffice, as the high cost of HSSE material may not be justified. It is also not suitable for right-hand threading applications, as the geometry is specifically designed for left-hand rotation.

Key specifications

• Thread size: M16
• Thread type: Left-hand (LH)
• Tolerance class: 6g
• Material: HSSE (Cobalt-alloyed high-speed steel)
• Standard: DIN-22568

How to use

To use the threading die, secure the workpiece firmly in a vice to prevent movement. Ensure the die is properly seated in a compatible die stock handle. Apply a high-quality cutting oil to both the workpiece and the die to reduce friction and heat buildup. Start the die squarely on the end of the rod, applying steady downward pressure while rotating clockwise for left-hand threads. Periodically reverse the rotation to break off metal chips, ensuring a smooth thread finish.

What to consider before purchase

• Verify that the workpiece material is compatible with HSSE cutting tools
• Ensure the die stock handle size matches the outer diameter of the die
• Confirm the required thread direction (left-hand) for your specific assembly
• Check that the machine or manual setup can provide sufficient torque for M16 threading

Usage recommendations

Always use appropriate cutting fluid specifically formulated for stainless steel to extend the life of the HSSE cutting edges and improve the surface finish of the threads.
