Thread Tap (left-hand) FANAR M10 N2-178001-0100, metric left-hand M10 tap

FANAR left-hand thread tap M10 (metric left-hand M10 tap) is a cutting tool designed to create or restore internal left-hand M10 threads in metal components. It is suitable for hand tapping or use in tapping machines where the workpiece or assembly requires a left-hand thread orientation. The tool is intended for workshop repair, maintenance and light manufacturing tasks involving standard M10 left-hand threaded holes.

Advantages

The FANAR M10 left-hand tap provides precise thread geometry for consistent engagement and reliable fit with corresponding bolts or studs. Its design supports both manual tapping and machine-assisted operations, offering versatility across repair and production environments. The tap is made to metric M10 specifications, ensuring compatibility with other metric left-hand threaded components and reducing rework when restoring damaged threads.

Suitable for

• Cutting new internal left-hand M10 threads in metal parts
• Restoring damaged or worn left-hand M10 threads during repair
• Manual tapping with a tap wrench or hand tool
• Machine tapping operations where left-hand threads are required
• Maintenance and light production of assemblies using M10 left-hand fasteners

When it may not be suitable

This tap is specific to left-hand M10 metric threads and is not suitable for right-hand threads, other diameters, or non-metric thread standards. It may not be appropriate for heavy-production environments that require specialized high-speed or indexable tooling designed for large-volume automated tapping.

Key specifications

• Thread type: internal left-hand metric thread
• Nominal size: M10
• Intended use: cutting or restoring internal threads
• Typical applications: metals and metal alloys (workpiece dependent)
• Operation method: manual tapping or machine-assisted tapping

How to use

Select a properly sized pilot hole for M10 left-hand threading according to standard hole charts for the material being tapped. Secure the workpiece and use cutting fluid appropriate for the metal to reduce friction and improve chip evacuation. For manual tapping, start the tap square to the hole and turn in the left-hand direction, advancing a partial turn and then reversing slightly to break chips. For machine tapping, set the machine for left-hand rotation and feed parameters suitable for the material and tap size. Clean chips from the flutes regularly and inspect the created thread for correct fit.

What to consider before purchase

• Confirm the required thread direction is left-hand and the size is M10
• Verify compatibility with the material you will tap (type of metal or alloy)
• Determine whether manual or machine tapping will be used
• Check required tap pitch if non-standard pitches are needed

Usage recommendations

Use appropriate cutting fluid, ensure correct pilot hole size and maintain steady left-hand rotation when tapping. Inspect the tap for wear before use and replace if flutes are damaged to avoid poor thread quality.
