FANAR WYGNIATAK M 3 DIN 371-C 6HX HSSE TIN - cutting tool, M3 thread, DIN 371-C

FANAR WYGNIATAK M 3 DIN 371-C 6HX HSSE TIN is a precision cutting tool designed for forming and producing M3 metric threads according to DIN 371-C. Manufactured from high-speed steel with cobalt (HSSE) and finished with a titanium nitride (TiN) coating, this tool incorporates six cutting edges (6HX) to deliver consistent thread geometry and extended tool life in industrial machining and toolroom environments.

Advantages

The HSSE material with TiN coating offers increased hardness and resistance to abrasive wear compared with uncoated high-speed steel, which helps maintain sharp cutting edges over longer production runs. The six-edge design distributes cutting forces across multiple flutes, reducing individual edge load and improving dimensional consistency of M3 threads. Conformance to DIN 371-C ensures compatibility with standard thread-forming processes and existing fixtures.

Suitable for

• Forming and tapping M3 metric threads in ductile metals and compatible alloys
• Industrial machining centers and manual toolroom tapping operations
• Batch production where improved wear resistance and repeatability are required
• Applications requiring conformity to DIN 371-C thread forming specifications

Key specifications

• Thread size: M3 metric
• Thread standard: DIN 371-C
• Material: HSSE (high-speed steel with cobalt)
• Coating: TiN (titanium nitride)
• Cutting edges: 6 cutting edges (6HX)
• Function: Thread forming / tapping (forming type)

How to use

Select a compatible tapping holder or machine spindle that accepts the tool shank and secure the workpiece firmly to prevent movement. Use appropriate cutting speeds and feed rates for HSSE with TiN coating and the workpiece material; consult tooling and material tables for initial parameters. Apply suitable lubrication or cutting fluid to enhance chip formation and reduce friction. Advance the tool steadily into the pre-drilled hole sized for M3 forming taps, control feed to maintain straightness, and retract as needed to break chips and clear the formed thread.

Usage recommendations

For best results, use when machining ductile materials specified for forming taps and ensure hole size matches the forming tap requirements for M3. Monitor tool wear and replace when thread quality or dimensional accuracy degrades. Use compatible cutting fluids and avoid excessive speeds to preserve the TiN coating and HSSE substrate.
