The Baer Heli Coil Tap - Wire Thread Insert - Spiral Flute Tap (STI) for Metric M14 x 1.5 is the precise, durable solution you need to repair and reinforce threaded holes. Built for professional results, this tap is designed to cut clean, accurate threads that accept Heli-Coil wire thread inserts with confidence, restoring strength where threads have worn or stripped away.
- Exact M14 x 1.5 thread profile tailored for standard Heli-Coil inserts, providing reliable engagement and repeatable results across multiple projects.
- Spiral flute geometry delivers aggressive cutting action and efficient chip evacuation, reducing chatter and producing clean, true threads even in confined or hard-to-reach holes.
- Rigorous build for durability engineered to withstand regular use in repair, maintenance, and manufacturing settings, helping you avoid frequent replacement.
- Versatile application ideal for repairing stripped threads in a variety of metals and components, from automotive housings to machinery and equipment housings, enabling durable, reusable threads.
- Designed for Heli-Coil installations seamlessly pairs with coil inserts to restore original strength and thread life, so assemblies stay secure through repeated assembly and disassembly.
Use cases and practical scenarios: when a threaded hole has lost its grip or become damaged, this tap lets you re-cut the thread to the correct M14 x 1.5 pitch, then install a Heli-Coil insert to regain full torque tolerance and pull-out resistance. It’s particularly valuable in repair shops, fabrication benches, and DIY projects where dependable, long-lasting threads are non-negotiable.
How to get the best results: lubricate lightly to reduce tool wear, steady the workpiece for straight alignment, and follow with a clean installation of the corresponding Heli-Coil insert. After use, wipe away any chips and store in a dry environment to preserve precision for future repairs.
