Overview
The Orion Motor Tech Thread Repair Kit is a comprehensive rethreading solution designed to restore damaged or stripped internal threads across a wide range of applications. This professional-grade kit combines both SAE and metric sizing options, making it an essential toolset for automotive repair, machinery maintenance, and general equipment restoration work.
This all-inclusive system features high-speed steel drill bits with 135-degree points for precise hole preparation, durable screw taps for clean thread cutting, and 264 wire thread inserts that create new, stronger threads in damaged holes. The kit covers ten of the most commonly needed sizes: 1/4 inch, 5/16 inch, 3/8 inch, 7/16 inch, and 1/2 inch in SAE measurements, plus M5, M6, M8, M10, and M12 in metric sizes, ensuring compatibility with the majority of threaded fastener applications.
Each component in this helicoil kit is manufactured from quality steel and undergoes heat treatment to enhance strength and extend service life. The included installation tools allow for proper depth finding and secure insert placement, while the tang break-off tools provide clean finishing touches by removing excess material once inserts are properly seated. The 135-degree drill bit angle enables quick material removal and smooth hole preparation for optimal insert installation.
The complete set arrives in a rugged carrying case that keeps all components organized and protected during transport and storage. Whether you're repairing spark plug threads, restoring bolt holes in engine blocks, or performing preventative maintenance on critical threaded connections, this versatile kit provides everything needed to complete professional-quality thread restoration work efficiently.

FAQs
Can this kit repair spark plug threads in aluminum cylinder heads?
Yes, the kit works excellently for spark plug thread repair in aluminum heads. The M12 and M14 sizes (depending on your spark plug specification) along with the included inserts create stronger threads than the original aluminum, providing a permanent repair solution.
Are the thread inserts permanent or can they be removed and reused?
The thread inserts are designed to be permanent installations once properly seated and the tang is broken off. They cannot be easily removed or reused, but they create a durable, long-lasting threaded connection that often exceeds the strength of the original material.
What materials can I use this thread repair kit on?
This kit works on aluminum, cast iron, steel, brass, and most other machinable metals commonly found in automotive engines, equipment housings, and machinery components. It is not suitable for extremely hard materials or plastics.
Do I need any additional tools to use this kit?
You will need a standard drill (corded or cordless) to operate the HSS drill bits and a tap wrench to turn the screw taps. All specialized installation and breaking tools are included in the kit.
How do the 135-degree drill bits differ from standard bits?
The 135-degree point angle provides better self-centering capability and requires less initial pressure, making it ideal for drilling into curved or angled surfaces often encountered in thread repair work. They also generate less heat during drilling compared to standard 118-degree bits.
Can this kit be used for external thread repair or only internal threads?
This helicoil kit is specifically designed for internal thread repair only. It restores damaged female threads in tapped holes but does not repair male threads on bolts or studs.
What is the purpose of the tang break-off tools?
After installing a thread insert, a small tang protrudes that was used during installation. The breaking pin tools cleanly snap off this tang flush with the insert, preventing interference with the bolt or screw that will be installed in the repaired thread.
