Tap FANAR NARZYNKA M16 DIN-22568 LH (6g) HSSE INOX – left-hand M16 cutting tap, HSSE stainless steel

FANAR NARZYNKA M16 DIN-22568 LH (6g) HSSE INOX is a left-hand M16 cutting tap made from high-speed steel with cobalt (HSSE) and optimized for use on stainless and other corrosion-resistant materials. Manufactured to DIN-22568 dimensions with a 6g tolerance, this tap produces internal left-hand metric threads with consistent form and dimensional accuracy. The geometry and material composition are selected to resist work hardening and wear when machining stainless steels and similar alloys.

Advantages

This left-hand M16 tap offers improved wear resistance and hardness due to the HSSE material, extending tool life when cutting tough, stainless materials. Conformance to DIN-22568 and 6g tolerance ensures interchangeability and reliable thread fit for mating components. Its cutting geometry reduces chatter and eases chip evacuation in internal threading operations on corrosion-resistant alloys. The left-hand orientation enables assembly or repair tasks where standard right-hand threads are not suitable.

Suitable for

• Cutting internal left-hand M16 threads in stainless steel and corrosion-resistant alloys
• Professional metalworking, maintenance and repair applications requiring precise internal threads
• Situations where left-hand threading is required for mechanical or assembly reasons

When it may not be suitable

This tap is specifically a left-hand tool for M16 threads; it is not appropriate when right-hand threads are required. It is intended for materials compatible with HSSE cutting tools—softer non-ferrous metals or plastics may not benefit from the HSSE properties and could require different tool geometry or coatings for optimal results.

Key specifications

• Thread size: M16
• Hand: left-hand threading
• Standard: DIN-22568
• Tolerance/class: 6g
• Material: HSSE (high-speed steel with cobalt)
• Intended workpiece materials: stainless steels and corrosion-resistant alloys

How to use

Select an appropriately sized hole and ensure correct alignment for left-hand threading. Secure the workpiece and use a suitable tap holder or machine setup that supports left-hand rotation. Apply a cutting fluid compatible with stainless materials to reduce friction and aid chip evacuation. Feed the tap at the correct pitch and reverse periodically if using hand operation to break chips. For machine tapping, set spindle speed and feed to match recommended values for HSSE taps and the specific stainless grade being machined.

What to consider before purchase

• Confirm you require a left-hand M16 internal thread rather than a right-hand thread
• Verify compatibility of HSSE tooling with the specific stainless grade or alloy you will machine
• Ensure your tapping equipment supports left-hand rotation or use a suitable hand tap holder

Usage recommendations

Use moderate cutting speeds and appropriate cutting fluid when threading stainless materials; ensure chip evacuation and avoid excessive feed or speed to reduce tool wear and achieve consistent thread quality.
