Tap FANAR M18x1.5 NGMM/1 DIN-2181D (6H) HSS — M18 x 1.5 metric thread

FANAR M18x1.5 NGMM/1 DIN-2181D (6H) HSS — M18 x 1.5 metric thread is a high-speed steel hand or machine tap designed to cut internal metric threads with a 1.5 mm pitch. Manufactured to comply with DIN 2181D and 6H tolerance class, this tap provides consistent thread geometry for repair, maintenance and production tasks in ferrous materials. The tool is suitable where standardized M18×1.5 internal threads are required and where a balance of durability and cutting precision is needed.

Advantages

This HSS tap offers good wear resistance and toughness for general workshop applications. Conformance to DIN 2181D ensures uniform thread profile and compatibility with standardized fasteners, while the 6H tolerance provides reliable fit and interchangeability. The tool can be used by hand or in machine tapping operations, making it versatile for different production and repair environments.

Suitable for

• Cutting M18 x 1.5 internal threads in steel and other ferrous materials
• Maintenance and repair of machinery and equipment requiring standardized metric threads
• Workshop and light production tapping operations

Key specifications

• Thread size: M18
• Pitch: 1.5 mm
• Material: high-speed steel (HSS)
• Standard: DIN 2181D
• Tolerance class: 6H
• Application: hand or machine tapping for internal metric threads

How to use

Select an appropriate pilot hole diameter for M18×1.5 and secure the workpiece. For hand tapping, use a suitable tap wrench and start the tap perpendicular to the workpiece, applying steady pressure and rotating with alternating forward and back turns to break chips. For machine tapping, use correct spindle speed and feed settings for HSS taps and ensure proper alignment with the hole. Use cutting fluid appropriate for ferrous materials to improve chip evacuation and extend tool life. After tapping, clear chips from the thread and inspect for correct fit and thread form.

Usage recommendations

Use recommended pilot hole diameters and cutting fluids for ferrous materials, avoid excessive spindle speed or feed that can overload the tap, and replace the tap when wear or distortion is visible to maintain thread quality and tolerance conformity.
