Tap FANAR NARZYNKA M18 DIN-22568 (6g) HSS-E INOX

FANAR NARZYNKA M18 DIN-22568 (6g) HSS-E INOX is a machine tap designed to produce metric M18 threads with 6g tolerance according to DIN 22568. Manufactured from high-speed steel with added cobalt (HSS-E) for improved red hardness and wear resistance, this tap is intended for industrial threading of stainless steel (INOX) and similar alloys. It is suitable for use in machining centres and on tapping heads, and can be applied for both through and blind holes depending on setup and tool selection.

Advantages

The HSS-E material provides higher heat resistance and longer cutting life when working with stainless steels compared to standard HSS taps. Compliance with the DIN 22568 geometry ensures consistent thread profile and interchangeability with standard M18 fasteners. The tool is balanced for machine use and compatible with common tapping systems, enabling stable cutting performance and predictable tool life under recommended cutting conditions.

Suitable for

• Threading M18 holes in stainless steel and corrosion-resistant alloys
• Use in machining centres and CNC tapping heads
• Production runs and repair work requiring DIN-compliant threads
• Through holes and blind holes where appropriate tool length and chamfer are selected

Key specifications

• Thread size: M18
• Tolerance: 6g
• Standard: DIN 22568 thread geometry
• Material: HSS-E (high-speed steel with cobalt)
• Application: designed for stainless steel (INOX) and similar materials
• Intended use: machine tap for mechanical tapping operations

How to use

Install the tap in a suitable machine tap holder or tapping head, ensuring correct axial alignment and secure clamping. Select appropriate spindle speed and feed based on the workpiece material and tap manufacturer recommendations for HSS-E taps in stainless steel. Use suitable cutting fluid for stainless steels to reduce heat and improve chip evacuation. For blind holes, control depth carefully to avoid breakage; for through holes, ensure adequate chip clearance. Inspect threads after tapping and de-burr as required.

Usage recommendations

Use moderate spindle speeds and steady feed to avoid work hardening of stainless steel. Apply appropriate coolant and ensure chip evacuation; when machining difficult grades, reduce speed and consider peck tapping or reverse chip-breaking cycles. Replace the tap at first signs of wear or chipping to maintain thread quality and prevent tool failure.
