Tap FANAR M22 NGMM/1 DIN-352D (6H) HSS – thread forming tap for M22, model E1-131001-0220

FANAR tap M22 NGMM/1 DIN-352D (6H) HSS, model E1-131001-0220, is a high-speed steel thread forming tap engineered for creating or restoring internal metric threads with nominal diameter M22. Manufactured to DIN-352D dimensions and a 6H tolerance class, the tool is intended for precision metalworking, maintenance, and toolroom applications where consistent thread geometry and dimensional accuracy are required. The solid HSS construction provides a balance of toughness and wear resistance suitable for general-purpose threading of steels and similar materials.

Advantages

The tap’s DIN-352D profile and 6H tolerance ensure compatibility with standard metric fasteners and help produce repeatable, accurate internal threads. Being a thread forming tap, it displaces material rather than cutting chips, which reduces the need for chip evacuation and can improve surface finish in ductile materials. The HSS material offers good resistance to abrasion and thermal stress during intermittent or moderate-duty threading operations. Its design supports reliable thread formation and long tool life when used in appropriate materials and with proper lubrication.

Suitable for

• Forming or repairing M22 internal threads in steel components
• Toolroom and maintenance threading operations
• General-purpose threading where DIN-352D and 6H tolerance compliance is required

Key specifications

• Thread size: M22 (metric internal thread)
• Tap type: NGMM/1 thread forming tap
• Standard: DIN-352D profile
• Tolerance class: 6H
• Material: high-speed steel (HSS)

How to use

Select the correct pilot hole diameter recommended for a forming tap to allow proper material flow during thread formation. Secure the workpiece and align the tap perpendicular to the hole axis. Use steady, controlled feeding pressure without reversing frequently to allow the tap to form threads by displacing material; apply an appropriate cutting or forming lubricant suited to the workpiece material to reduce friction and heat. After completing the pass, back the tap out carefully to avoid damaging the formed thread. Inspect the thread for dimensional conformity to DIN-352D and the required fit.

Usage recommendations

For best results, use with correct pilot hole size and appropriate lubrication; avoid use in brittle materials unsuited to thread forming, and monitor tool condition to maintain thread quality.
