FANAR WYGNIATAK M 5 DIN 371-C 6HX SR HSSE-PM WGN TiCN – hand tap M5, DIN 371-C, 6H thread, HSSE-PM, TiCN coating

FANAR WYGNIATAK M 5 DIN 371-C 6HX SR HSSE-PM WGN TiCN is a machine and hand tap designed to produce M5 metric threads to DIN 371-C specification with 6H tolerance. Constructed from HSSE-PM tool steel for enhanced wear resistance and toughness, the tap features a TiCN surface coating and a short-radius (SR) flute geometry that promotes reliable chip formation and evacuation. The design supports both through-hole and blind-hole tapping in steels and common engineering materials, making it suitable for workshop and light industrial applications.

Advantages

The HSSE-PM material provides high hardness and resistance to abrasive wear while retaining impact strength for reduced breakage risk during hand or machine tapping. TiCN coating lowers friction and increases tool life, especially when tapping steels and tougher alloys. The short-radius flute improves chip control and reduces clogging in interrupted cuts and pre-drilled holes, and the DIN 371-C geometry ensures consistent thread form and engagement to the 6H tolerance class.

Suitable for

• Tapping M5 threads in mild and alloy steels
• Through-hole and blind-hole tapping operations
• Workshop, maintenance and prototyping tasks
• Hand tapping with tap wrench or machine tapping with suitable holders

Key specifications

• Thread size: M5 metric
• Thread standard: DIN 371-C
• Tolerance class: 6H
• Material: HSSE-PM tool steel
• Surface finish: Titanium carbonitride (TiCN) coating
• Flute style: Short-radius (SR) flute for improved chip control
• Application: Through and blind hole tapping in steels and general engineering materials

How to use

Use an appropriate pilot drill to achieve the correct core diameter for M5 threads and ensure precise alignment of the tap with the hole axis. For hand tapping, use a tap wrench with steady, straight pressure, backing off periodically to break chips. For machine tapping, select correct spindle speed and feed, and use suitable holders or collets to maintain axial alignment and minimize runout. Apply an appropriate cutting fluid for steel to reduce friction and extend tool life. Inspect threads after tapping for correct form and clean any remaining chips from the hole.

Usage recommendations

Choose cutting speeds and feeds appropriate for HSSE-PM with TiCN coating and the workpiece material; moderate speeds with steady feed are generally recommended for steel. Maintain sharp, undamaged taps and replace tools showing wear or chipping to prevent poor thread quality or tap breakage. When tapping blind holes, frequently retract to remove chips and avoid chip packing at the flute ends.
