This AB Tools Whitworth Tap Repair Cutter Kit is designed for professionals and DIYers needing to repair damaged or stripped internal threads. Its key benefit is providing a permanent, stronger thread repair in soft materials using British Standard Whitworth sizing. A potential caveat is the specific thread size (1/8" x 40 BSW) which requires a precise application.

This kit is specifically for repairing 1/8" x 40 TPI British Standard Whitworth (BSW) threads.
It is ideal for repairing threads in soft materials like aluminum, brass, and plastics, creating a stronger thread than the original.
The lug breaking tool is used to snap off the small tab (tang) at the bottom of the installed Helicoil insert after it has been seated.
It is designed for stripped or worn internal threads. It may not be effective for severely cross-threaded or physically deformed holes.
A Helicoil insert is a coiled wire thread that is screwed into a pre-tapped hole to form a permanent, stronger internal thread.
The set includes 10 inserts with a 3mm thread length.
No, this kit is exclusively for 1/8" x 40 BSW (British Standard Whitworth) threads and is not compatible with metric or other imperial sizes.
Ensure the hole was drilled to the correct size and the new threads were tapped cleanly with the provided tap. Check for debris in the hole or on the insert.
Verify the insert was fully seated and the tang was properly broken off. Ensure the original material was suitable for thread repair.
Ensure the drill bit is sharp and properly aligned with the damaged thread. Apply steady pressure and use appropriate speed.
Use cutting fluid or oil. Ensure the tap is perpendicular to the surface and backed out periodically to clear chips.
Setup: Ensure you have the correct thread size (1/8" x 40 BSW). Identify the damaged thread. Use the provided 4mm drill bit to carefully drill out the damaged area. Clean the drilled hole. Use the 1/8" x 40 thread tap to cut new threads into the hole. Screw the Helicoil insert into the newly tapped threads using the installation tool until it is flush with the surface. Finally, use the lug breaking tool to snap off the tang of the insert, ensuring a smooth finish.
Compatibility: This kit is specifically designed for 1/8" x 40 BSW (British Standard Whitworth) threads. It is not compatible with metric or other imperial thread forms.
Care: After use, clean all tools thoroughly to remove debris. Store all components in the provided blow-molded case to prevent loss and protect them from damage. Keep the case in a dry environment.
