Cutting Tap FANAR WYGNIATAK M 4 DIN-371C HSSE-PM WGN TIN without flute

FANAR WYGNIATAK M 4 DIN-371C HSSE-PM WGN TIN without flute is a solid cutting tap engineered for producing M4 metric internal threads. Manufactured from HSSE-PM high-speed steel with powder metallurgy and finished with a WGN TiN coating, this tap is intended for applications requiring a solid shank without flutes. Its DIN-371C geometry supports standard-form thread generation in compatible base materials and is suitable for both manual and machine tapping operations where non-fluted tool geometry is necessary.

Advantages

The HSSE-PM material offers improved wear resistance and toughness compared with conventional HSS, while the WGN TiN coating reduces friction and extends tool life under repeated use. The solid, no-flute construction provides stable clamping and predictable engagement in specialized setups. DIN-371C thread form ensures dimensional compliance with metric internal thread standards for M4, facilitating consistent results when used under recommended cutting conditions.

Suitable for

• Forming or cutting M4 metric internal threads in components requiring a solid shank tap
• Machine and manual tapping processes where non-fluted geometry is specified
• Metalworking operations on materials compatible with HSSE-PM and TiN-coated tooling
• Situations demanding enhanced wear resistance and surface finish from coated high-speed taps

Key specifications

• Thread size: M4 metric
• Standard: DIN-371C (metric internal thread form)
• Material: HSSE-PM (high-speed steel, powder metallurgy)
• Coating: WGN TiN (titanium nitride)
• Construction: solid, without flute

How to use

Select appropriate tapping speed and feed based on the workpiece material and machine capability, using cutting fluids compatible with TiN-coated tools when applicable to reduce heat and improve chip evacuation. Mount the tap securely in a suitable holder or chuck that supports solid shank tools, ensuring correct axial alignment. For manual tapping, use controlled torque and a steady feed to avoid overtightening; for machine tapping, follow machine manufacturer recommendations for plunge and retract cycles. Inspect the formed threads and the tool periodically for wear and replace the tap when thread quality degrades.

Usage recommendations

Use appropriate cutting lubricant for the material being machined, avoid excessive axial force, and verify machine setup and clamping to preserve thread accuracy and maximize tool life. Store the tap in a dry environment to prevent corrosion and inspect coating integrity before use.
