Ever struggled with a helicoil that won’t come out? I know the feeling. Whether it’s stripped, stuck, or just needs replacing, learning how to remove a helicoil the right way can save you a lot of trouble. I’ve tackled plenty of these, and trust me, there’s an easy way to do it. In this guide, I’ll show you simple methods, whether you have a helicoil removal tool or not. Let’s get started!

Understanding Helicoil Inserts
Ever had a bolt spin freely in a hole where it should grip tight? That’s where a helicoil insert comes in. It’s a small, coiled wire that restores stripped threads, giving them a second life. I’ve used them plenty of times to fix damaged threads in aluminum and steel, and they work like magic—until you need to take one out.
So, why remove a helicoil? Maybe it was installed wrong, got stripped, or isn’t the right size. Sometimes, a helicoil breaks off inside the hole, making removal even trickier. If you’ve ever fought with a stuck, deep, or broken helicoil, you know how frustrating it can be. The good news? There are ways to get it out without damaging the threads underneath. I’ll show you exactly how!
Best Ways to Remove a Helicoil (Step-by-Step Guide)
Removing a helicoil can feel tricky, but I promise it’s easier than it looks. I’ve had my fair share of stuck, stripped, and broken helicoils, and with the right approach, you can get them out without damaging the threads. Whether you have a helicoil removal tool or need a DIY fix, I’ll walk you through the best methods.
A. Using a Helicoil Removal Tool
If you want the easiest, cleanest removal, a helicoil removal tool is your best option. These tools grip the coil, unwind it, and pull it out smoothly. Some of the best options include:
- KATO Helicoil Removal Tool – Works great for precision jobs.
- Snap-on Helicoil Removal Tool – A solid choice for professionals.
- Helicoil Removal Tool Harbor Freight – Affordable and effective.
✅ Quick Tip: Insert the tool into the helicoil, twist counterclockwise, and gently pull. If it resists, try again with steady pressure.
B. Removing a Helicoil Without a Tool
No special tool? No worries! I’ve removed helicoils using everyday tools like:
- Needle-nose pliers – Grab the end of the coil and twist it out.
- A small screwdriver – Pry up the edge and start unthreading.
- A tap or extractor – If the helicoil is deep, this can help.
✅ Pro Trick: If the helicoil won’t budge, tap it lightly with a hammer. This helps loosen its grip inside the hole.
C. Removing a Stripped, Stuck, or Broken Helicoil
This is where things get tricky. A stuck helicoil won’t turn easily, and a broken one can leave sharp edges inside the hole. Here’s what I’ve found works best:
- For deep helicoils in aluminum or steel – Use a small drill bit to break the coil free.
- For a stuck insert – Apply heat with a soldering iron to expand the metal slightly.
- For a broken helicoil – Use a Dremel or extractor to grab and twist it out.
✅ Avoid Mistakes: Don’t force it! Too much pressure can damage the hole. Work slowly and carefully.
D. Removing a Helicoil for a Spark Plug
Spark plug helicoils sit in delicate engine threads, so extra care is needed. If you’re dealing with one, follow these steps:
- Use a helicoil removal tool (or pliers if it’s loose).
- Turn counterclockwise gently—rushing can strip the hole.
- If stuck, apply penetrating oil and wait a few minutes before trying again.
✅ Extra Caution: Engine threads are soft. If you’re unsure, ask a pro to avoid costly repairs.

Can You Reuse a Helicoil After Removal?
I get this question a lot: Can you reuse a helicoil after taking it out? The short answer? Not really. Once a helicoil has been installed and removed, it loses its grip and shape, making it less reliable for reinstalling.
Think of a helicoil like a spring—once stretched, it doesn’t snap back the same way. Even if it looks intact, the threads might be weakened or deformed, meaning it won’t hold as securely the second time around. When I’ve tried reusing one in the past, it either didn’t sit right or stripped out easily, causing more trouble than it was worth.
The best move? Replace it with a new one. Helicoils are affordable and designed for single-use installation. A fresh insert ensures a strong, reliable hold, saving you from future headaches. If you’re fixing a critical part like an engine block or spark plug hole, don’t take chances—go with a new helicoil for peace of mind.
