## Description

Heat Set Insert Tip for M3 with 30 M3 Inserts - 3D Printing Accessories Compatible with Hakko FX-888D and Weller SP40NUS Irons, Soldering Iron Tips for Threaded Inserts

## Features

- IMPROVING 3D PRINTING PROJECTS: Using 3D printers lets you create amazing projects. Innovative 3D printing tools like Virtjoule Heat-Set Insert Tips allow you to set threaded brass inserts into plastic to increase the strength of your part and also help you assemble and disassemble projects multiple times. These soldering tips, compatible with Hakko FX-888D and Weller SP40NKUS solder irons, make the job easy. With their square shoulder and slick finish, inserts won't stick on the tool and pull out.
- OPTIMIZED SLIM PROFILE DESIGN: We originally created these long-shank tips to be compatible with the Hakko FX-888D iron. This design allows you to reach deeper into 3D-printer parts and tight corners without touching the side of your 3D-printed or injection molded part. The hot iron heats the tip and the brass insert, allowing it to melt into the piece. When set, the iron pulls out cleanly without sticking. A normal conical shape tip will often stick to the insert and pull it back out, ruining the project.
- M3 THREADED INSERT PACK: Each Virtjoule Heat Set Insert Tip for M3 has 30 threaded inserts for the M3 tip. M3 is a popular size for Arduino circuit board hole mounts. Not all M3 inserts you may find have the same outer diameter. So check your design with the inserts you have.
- EASE OF USE: These installation tips install by sliding over the ceramic heating element of the Hakko irons, just like the soldering iron tip, while still fitting in the 1/4" chamber of a Weller SP40NKUS. We have not tested every possible soldering iron. Most iron makers have dozens of models that may not be compatible and so it's important to check your model number for compatibility.
- DIAMETER & HEAT TRANSFER OPTIMIZED TIPS: Virtjoule pioneered the niche of brass insert tips with shapes that allow access to tight and deep corners of 3D printed parts. We serve 3D printer and injection molding markets of scientists, engineers, designers, and makers with insert tips that reliably and efficiently release heat-set inserts from soldering irons.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Perfect for Hakko FX-888D.  WORKS GREAT!
  

*by R***. on Reviewed in the United States on June 1, 2022*

Finally had a chance to try out the new Hakko M3 tip and inserts.  For a beginner, I’m pretty happy how the tests are coming out.  I grabbed a scrap 3D printed part to get some practice.  The seller's videos really helped out.  Drilled a 3.55 mm (9/64”) hole (I didn’t print in the hole I was testing, just drilled it instead)  That turned out to be a really good hole size.  Insert went right in, but still grabbed.  I didn’t debur the hole or anything and the outer melted edge was flush to the piece.  Was really easy and I have a lot of confidence to start designing this into my parts.  Tip was a perfect fit for my Hakko FX888D.

    Awesome inserts!!!!!
  

*by J***N on Reviewed in the United States on June 7, 2022*

I already had a Hakko soldering iron so the tip fit perfect!!! After installing the tip into my iron the inserts went in like butter. Just printed a new housing for Big Tree Tek display and these inserts worked flawlessly. Very happy.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great inserts and the tip worked well
  

*by S***L on Reviewed in the United States on July 2, 2022*

I bought these to use when assembling a "Hero ME Gen 6" fan shroud for a Creality Ender 3 printer. The inserts are just the right size for that, and the included tip makes it easier to set the tips correctly than using the pointed end of a normal soldering iron. I even bought the appropriate Weller iron so that I could use this insert (since it would not work with my ancient RadioShack iron.)
