Hand taps FANAR M22 x 2.50 6H HSS, 2-piece set (DIN 352/2)

FANAR hand taps 2-piece set M22 x 2.50 6H HSS to DIN 352/2 is a manual tapping set designed for cutting ISO metric M22 x 2.50 threads with a 6H tolerance class. The set contains the standard sequence of two hand taps for producing consistent internal threads in through and blind holes. Manufactured from high-speed steel (HSS), the taps are intended for general engineering use and are suitable for working in steel, non-ferrous metals and similar materials.

Advantages

The HSS material provides good hardness and wear resistance for manual threading operations. The two-piece sequence ensures proper progressive cutting and reduces the risk of tap breakage when used correctly. Conformance to DIN 352/2 and ISO metric thread form offers predictable thread geometry and compatibility with standard M22 x 2.50 fasteners. The set format is compact and convenient for workshop or field use.

Suitable for

• Manual tapping of through holes in steel and non-ferrous metals
• Manual tapping of blind holes with appropriate care and lubrication
• General engineering repairs and maintenance
• Workshop use where ISO metric M22 x 2.50 threads are required

When it may not be suitable

This hand tap set is intended for manual tapping rather than high-volume production on machines. For very hard materials, hardened steels or abrasive alloys, machine taps or taps with special coatings and geometries may be more appropriate. The two-piece hand tap sequence requires correct use and adequate lubrication; improper alignment or excessive feed can lead to tap damage.

Key specifications

• Thread size and pitch: M22 x 2.50
• Tolerance class: 6H (internal thread tolerance)
• Material: high-speed steel (HSS)
• Standard: DIN 352/2
• Set composition: 2 hand taps (standard taper/plug/finishing sequence as per set design)
• Application: manual tapping of through and blind holes in steel and non-ferrous metals

How to use

Select an appropriate drill size for the M22 x 2.50 core bore, clamp the workpiece securely and align the tap square to the hole. Use cutting fluid or suitable lubricant and start with the first tap in the set, applying steady, even pressure and backing off periodically to clear chips. After reaching the required depth with the first tap, switch to the second tap to achieve the final thread profile and required tolerance. Maintain straight alignment and avoid excessive torque to reduce the risk of tap breakage.

What to consider before purchase

• Confirm the thread size and pitch required: M22 x 2.50
• Verify compatibility of the 6H tolerance class with mating parts
• Consider material of workpiece (steel, non-ferrous metals) and need for lubrication or coolant
• Assess whether manual hand taps are suitable versus machine tapping or coated/special taps for hard materials

Usage recommendations

Use appropriate cutting fluid, keep the tap aligned, and remove chips frequently. For blind holes, retract and clear chips more often to prevent clogging. Replace taps showing wear or chipping to maintain thread quality and safety.
