Cutting Tool FANAR WYGNIATAK M 4 DIN-371C (6HX) SR HSSE-PM WGN TiCN

FANAR WYGNIATAK M 4 DIN-371C (6HX) SR HSSE-PM WGN TiCN is a precision cutting tool intended for producing or restoring metric M4 external threads using DIN‑371C tool geometry. Manufactured from high-speed steel with powder metallurgy (HSSE‑PM) and finished with a titanium carbonitride (TiCN) coating, the tool is designed to provide consistent thread form, improved wear resistance and stable cutting performance in a range of general metalworking operations.

Advantages

The HSSE‑PM substrate delivers a fine microstructure and toughness that reduce chipping and extend tool life compared with conventional high-speed steels. The TiCN coating increases surface hardness and reduces built-up edge, improving wear resistance and maintaining dimensional stability of threads over longer production runs. DIN‑371C geometry ensures the correct flank angles and thread profile for standard metric external threads, while the single‑point design enables precision thread forming and reparative cutting on shafts and cylindrical parts.

Suitable for

• Producing metric M4 external threads on shafts and cylindrical workpieces
• Repairing or reconditioning damaged M4 threads on steel and alloy components
• Short to medium production runs in general machining shops
• Applications requiring accurate thread form and repeatability

Key specifications

• Thread size: M4 external
• Tool geometry: DIN‑371C (6HX style thread form)
• Material: HSSE‑PM (high speed steel, powder metallurgy)
• Coating: TiCN (titanium carbonitride)
• Tool type: single‑point cutting / threading tool
• Typical use: cutting/forming external metric threads

How to use

Mount the tool securely in a suitable holder or tool post compatible with single‑point threading operations, ensuring correct axial and radial alignment with the workpiece. Set spindle speed and feed corresponding to the M4 pitch and the material being machined, and apply appropriate cutting fluid if machining steels or alloys to assist cooling and chip evacuation. Use gradual engagement and verify thread form with gauges after the pass; make small adjustments to depth of cut and feed to achieve the required dimensional tolerance and surface finish.

Usage recommendations

For best results, follow machining parameters recommended for HSSE‑PM tools when working with medium to high carbon steels and alloyed materials: moderate cutting speeds, steady feed matching thread pitch, and suitable lubrication. Inspect the tool regularly for wear or coating damage and recondition or replace when thread quality or dimensional accuracy declines. When repairing threads, remove burrs and ensure concentricity of the workpiece before threading to avoid premature tool wear.
