Designed and manufactured in the USA. The original long shank tip for the Weller WES51/WESD51 irons. If you see others with these shapes not made by Virtjoule, they are copy cats. Longer shank than other tips 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.

Tip sizes include M2, M2.5, M3, M4, and M5. M2.5 is a popular hole size for Raspberry Pi circuit boards. M3 is a popular size for Arduino circuit boards.

Weller makes many models of soldering iron which have their own size and shape tips. Make sure yours is compatible with WES51 or WESD51 irons or the Weller PES51 wand which is what those irons use. This is modeled after the ET series tips. We have found that not all ET series tips are the same, so make sure your iron or wand is the same or similar to those mentioned above.

Compact tip cradle included to keep them together when they're not being used. Wide size range gives you lots of flexibility to choose the right insert for your 3D printing project.

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. Virtjoule's insert tips 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 insert tips (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. These tips are 1.6" (40.7 mm) long. There is a 1/8" internal cavity for ceramic heaters. Five tips included for sizes M2, M2.5, M3, M4, and M5. Not tested with every possible soldering iron and will not fit all Weller irons Inserts and soldering iron not included. Not to be used for soldering. Designed, manufactured, and continuously improved in the USA.
