Tap (gwintownik) FANAR M2.5 DIN 371B HSSE-PM TiN 6H, hand/portable

FANAR M2.5 tap in DIN 371B form is a high-speed steel with cobalt (HSSE-PM) cutting tool with a Titanium Nitride (TiN) coating designed for producing internal metric threads M2.5. The tool is manufactured for hand and portable machine tapping operations and features a 6H tolerance fit for standard metric assemblies. The combination of powder metallurgy HSSE and TiN surface treatment provides enhanced wear resistance and prolonged service life in small-diameter threading tasks often encountered in metalworking, electronics housings and precision assemblies.

Advantages

The HSSE-PM material delivers improved toughness and heat resistance compared with conventional high-speed steels, while the TiN coating reduces friction and increases surface hardness to slow wear. The DIN 371B form and 6H tolerance ensure reliable thread geometry and interchangeability with standard metric fasteners. The tap is suitable for hand or portable tapping where control and accessibility are important, offering stable cutting performance in small-diameter threads.

Suitable for

• Creating internal M2.5 metric threads in metals and alloys
• Hand and portable tapping operations in tight or hard-to-reach areas
• Precision assembly work in electronics, instrumentation and small mechanical devices
• Repair and maintenance tasks requiring accurate small-thread reproduction

Key specifications

• Thread size: M2.5
• Form: DIN 371B
• Material: HSSE-PM (high-speed steel with cobalt, powder metallurgy)
• Surface finish: Titanium Nitride (TiN) coating
• Tolerance class: 6H
• Intended use: hand/portable tapping and machine tapping

How to use

Select proper pilot hole diameter according to M2.5 DIN recommendations and secure the workpiece to prevent movement. For hand tapping, align the tap with the hole axis and apply steady, even pressure while turning; use a three-turn forward, one-turn back sequence when cutting to break chips if necessary. For portable or machine tapping, ensure correct spindle alignment and appropriate spindle speed for the material being machined. Apply suitable cutting fluid to reduce friction and improve chip evacuation, particularly when working with harder alloys.

Usage recommendations

Use appropriate cutting lubricant and maintain alignment during tapping to maximize tool life. Inspect threads after cutting for correct form and fit with mating fasteners; replace the tap when wear or coating degradation affects thread quality. Store the tap in a dry, protected container to preserve the TiN coating and cutting edges.
