Heat set inserts are a great way to improve connection strength between 3D printed parts. However, if you have tried to set heat-set inserts in your plastic or 3D printed part with your soldering iron, you may have had the frustration of pushing the insert in only to have it come right back out stuck to your soldering iron and ruining your part in the process. Most soldering iron tips can catch on the rim of the insert causing it to stick on the iron when you pull the iron out. If you use the “horizontal method” it’s hard to know the insert is straight. Our inserts have a vertical wall that solves that problem. The iron pulls right out after pressing the hot insert. Because the shoulder is square it’s easier to know if the insert is square in the piece, something that’s harder to control with a conical soldering tip. The shank is much longer (0.75″) and narrower than what you get with the McMaster-Carr insert tip (only 0.25″ long), allowing you to set small inserts into corners of parts without melting the side of the part. This is especially useful if you’re mounting a circuit board in a 3D printed box or doing a mounting that requires the insert to come close to the edge of the part. Who wants to pay $15 plus shipping just for one size McMaster tip that is only a few millimeters long and only good for a few types of applications? Who wants to buy another soldering iron just to fit the tip? Compatibility with 1/4″ Weller insert and set screw style and internal ceramic heating element units like Hakko hopefully will let you use the iron you already own. These tips are 1.6″ (40 mm) long with the tip portion about 0.75″ (19mm). There is a 5/32″ internal cavity for ceramic heaters. On Weller irons, the 1/4″ shank can be extended as far as the set screw will allow. On Hakko irons, the 0.75″ is the reach with 1/4″ clearance. Two tips included, one for #4-40 and M3 and the other for M5 inserts.
- Longer shank than McMaster tip allows you to reach deeper into 3D printed parts and tight corners to install heat-set inserts without touching your iron and melting the plastic
- Installation tip works better than soldering iron tip since conical tips can catch on the insert and accidentally pull the insert out while melting the plastic and ruining the part.
- One tips works for #4-40 and M3 and the other tip works for M5 inserts for same price as one McMaster tip. More types of inserts and better reach than other installation tips.
- Tips are compatible with both 1/4″ Weller irons and internal ceramic heaters of many Hakko models. No other tip is compatible with both kinds of soldering irons. McMaster tip is not at all compatible with Hakko irons. These installation tips slide 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 iron.
- Not intended to be used for soldering. Soldering iron not included.
