If you’re looking for a solution to damaged threads or a way to create stronger, more reliable threads in metal materials, then a helicoil insert tool is an essential piece of equipment. But with so many options available on the market, it can be tough to choose the right one for your needs.
In this article, we’ll explore everything you need to know about helicoil insert tools. From their different types and sizes to how they work and how to use them properly, we’ve got you covered. So let’s dive in!
Types of Helicoil Insert Tools
When it comes to choosing a helicoil insert tool, there are two main types to consider: manual tools and power tools.
Manual Tools
Manual helicoil insert tools are designed for use by hand. They typically consist of a mandrel (a threaded rod) and an installation tool (a sleeve). The mandrel is inserted into the damaged thread hole, while the installation tool is used to screw the helicoil insert into place.
Manual tools are perfect for smaller jobs or situations where access is limited. They’re also ideal for those who prefer hands-on work or who don’t have access to power tools.
Power Tools
Power helicoil insert tools, as the name suggests, are powered by electricity or air pressure. They come in various shapes and sizes, from handheld drills to larger bench-mounted machines.
These tools are great for larger jobs or situations where speed is essential. They’re also ideal for those who want to save time and effort by using an automated tool.
Size Matters
When it comes to choosing the right size of helicoil insert tool, there are three main things to consider: the diameter of the hole you’re working on, the external diameter of the helicoil insert itself, and the thickness of the material you’re working with.
The diameter of the hole you’re working on will determine the size of the mandrel you need. The external diameter of the helicoil insert will determine the size of the installation tool you need. And the thickness of the material you’re working with will determine the length of the helicoil insert required.
It’s essential to choose the right size and length of helicoil insert for your needs, as using a tool that is too large or too small can cause damage to your threads or result in an unstable fixing.
How Helicoil Insert Tools Work
Helicoil inserts work by creating new threads in damaged or worn-out thread holes. They consist of a coiled wire, which is inserted into the hole and then screwed into place using a helicoil insert tool.
Once in place, the helicoil insert provides a new set of threads for bolts or screws to be fastened securely into. This not only repairs damaged threads but also creates stronger and more reliable fixing points than before.
Using Your Helicoil Insert Tool
Now that you know about the different types and sizes of helicoil insert tools and how they work let’s take a look at how to use them properly.
Step 1: Prepare Your Materials
Before you begin, ensure that you have all the materials you’ll need for your job. This includes your helicoil insert tool, helicoil inserts, lubricant (such as cutting oil), and any other necessary tools.
Step 2: Drill Out Damaged Threads
If you’re repairing damaged threads, start by drilling out the old threads using a drill bit that matches the diameter of your chosen helicoil insert. Be sure to use cutting oil to prevent overheating and prolong tool life.
Step 3: Tap New Threads
Next, tap new threads into the hole using a tap that matches your chosen helicoil insert. Again, use cutting oil to prevent overheating and prolong tool life.
Step 4: Insert Your Helicoil
Once you’ve tapped new threads, it’s time to insert your helicoil. Thread the helicoil onto your mandrel, ensuring that it’s fully wound around the mandrel.
Then, screw the mandrel into your newly tapped hole until it reaches the bottom. Hold the installation tool against the top of the helicoil and gently turn it clockwise. This will cause the helicoil to expand and grip onto the walls of the hole.
Step 5: Remove Your Mandrel
Once your helicoil is securely in place, unscrew your mandrel from the hole, leaving the helicoil behind.
Step 6: Finishing Touches
Finally, use a thread locker or adhesive (if necessary) to ensure that your new fixing point is secure. And that’s it – you’re done!
Conclusion
A helicoil insert tool is an essential piece of equipment for anyone working with metal materials. By repairing damaged threads or creating stronger fixing points than ever before, these tools provide a reliable solution for any situation.
When choosing a helicoil insert tool, consider factors such as size, type, and material thickness to ensure that you get the right one for your needs. And when using your tool, remember to follow proper procedures and take all necessary safety precautions.
By following these tips and tricks, you’ll be well on your way to becoming a pro at using a helicoil insert tool. Happy fixing!
