5Pcs Heat Set Insert Tips for M2,M2.5,M3,M4,M5 Threaded Inserts, Compatible with Weller WES51 WESD51 PES50/51 WE1010NA WCC100 LR21 Soldering Irons ET Tips, Used for Connecting 3D Printed Parts

I recently purchased the HanTof Heat Set Insert Tips, and they exceeded my expectations! These insert tips proved to be dturdy and compatible with my Weller WE1010NA, making them an ideal addition to my 3D printing toolkit.What truly stood out was their seamless functionality. I used these insert tips to insert female thread knurled nuts into my 3D printed parts, and the process was remarkably smooth. The tips facilitated the insertion process without a hitch, ensuring a snug fit for the nuts into the printed parts. As a result, the assembled 3D printed components are now impressively sturdy, and I have complete confidence in their durability without any concerns about potential failures.The compatibility with my Weller WE1010NA was a huge plus, allowing for seamless integration into my existing setup without any compatibility issues or need for adjustments.I recommend the HanTof Heat Set Insert Tips to any fellow 3D printing enthusiasts or professionals. They effortlessly serve their purpose, making the process of inserting female thread knurled nuts into 3D printed parts a breeze.

Fits my Weller soldering iron great and does the job nicely. Much better than using soldering tips.

Woks like a charm! Able to melt in screw treads straight and true. Don’t technically “need” them, but I always use them!

I recently picked up these heat set insert tips for a project I was working on and I have to say, I'm really impressed with the quality of these tools. The 5 different sizes (M2, M2.5, M3, M4, and M5) are perfect for the various threaded inserts I was working with, and they fit snugly and securely. The heat set process was smooth and easy, and the end result was a nice, clean installation. Overall, I highly recommend these tips if you're in need of a reliable and affordable set for your threaded insert needs.

The media could not be loaded. So, on one hand, it seems like they pretty much nailed the dimensions to get it to fit onto a Weller iron and their proprietary tip dimensions. It slides tightly onto the ceramic heater core, and the jacket that retains the tips slides right over this tip itself. So bravo there, they seem to be the only ones who got that right.Unfortunately, at least with the M3 tip, it will not fit into the heat set inserts themselves. While you could probably still get it hot enough to melt most plastics without it seating inside of the inserts, the issue is without the pin seating directly into the insert, you will: 1. get poor heat transmission into the part, making the installation slower and more frustrating; 2. struggle to get the insert to go in square to the part surface, which can have a negative impact to actually putting all of your final parts together; 3. without the pin inside of the threads of the insert, plastic can flow up into the insert itself and clog it, making it not only useless, but potentially impossible to remove.The attached video should illustrate what I am talking about. The inserts shown are from McMaster, so I trust their dimensions to be accurate. I don't know if the dimensions of my tips are off because of a manufacturing defect or a design defect, but the end result is the same: I can't actually use these tips to install heat set inserts. Or I could, but I couldn't really expect results all that much better than just using regular chisel tip on my iron.

Did exactly what they were supposed to do. Works well with my Weller soldering iron.

These are nicely turned, and fit my WESD51 iron nicely. Just waiting for the next project that needs them for a full use test, but I expect them to work very well based on what I see so far.

The inside diameter of the are wrong. I'm not sure if they are all like this, or just my set, but they did not fit my soldering tool as advertised.
