M2, M2.5, M3, M4, M5 tips compatible with Hakko FX888D soldering iron Designed and manufactured in the USA Compatible with the Hakko FX888D iron. M2, M2.5, M3, M4, and M5 sizes. Greatly increase connection strength between 3D printed parts. Connect and disconnect parts reliably and indefinitely without stripping plastic Heat set insert installation tips compatible with Hakko FX888D soldering irons Strengthen and connect 3D printed and injection molded parts Heat set inserts are a great way to improve connection strength between 3D printed parts. Don't ruin your 3D printed part by messing up the insert installation. Our installation tips have square shoulders and vertical walls that let them slide back out of the insert without catching or pulling the insert out accidentally. Long shank allows you to reach deep into 3D printed parts. Each tip is optimized for width and mass to allow insert installation into tight corners without melting the side plastic. Vertical wall allows easy release of insert once installed. Square shoulder makes it easy to know if the insert is installed straight. A must- have for every 3D printer toolbox. Not intended for soldering. Soldering iron not included. Read more How do you use heat set inserts? Design your part with holes for inserts Create your design with holes or pre-drill holes for where the insert is going to be placed. These holes need to be a little smaller than outer diameter of the insert and about 10-15% deeper than the length of the insert so that plastic will melt, deform, and mold around the insert properly. You may need to experiment with your 3D printer as some are not very accurate and the inserts themselves can have different outer diameters even if they are the same thread size. Heat iron to plastic melting temperature The hotter the iron, the faster the melt will happen. This may be desirable in a production environment. If you are a beginner, set the temperature right at the melting temperature of the plastic you're using or the extrusion temperature of your 3D printer. ABS - between 490 and 700 F (255-371C) PLA - 356F to 428F (180 - 220 C) If the plastic begins to smoke, lower the temperature. If no melt happens or too much pressure is required, raise temperature. Even plastics within the same type may have slightly different melting properties and you may have to experiment a bit. Horizontal method-See listing video If an insert is placed onto the tip when the iron is horizontal, you can press the insert directly into the piece if you keep the iron horizontal. Because the tip is designed to not hold onto the insert, if the insert is placed on the tip and then oriented vertically, the insert will fall off. Holding the piece in one hand and using the iron with the insert on the tip in the other hand and pressing horizontally. This is our favorite method. Vertical method-See listing video If installing with the iron horizontal is not convenient or too difficult, you may need to install the insert in a vertical orientation. Place the insert over the hole it's going into first taking care to make sure the insert is sitting square over the hole. Use some needle nose pliers to hold it there, if you need to. Then use the tip of the iron and place it inside the insert and begin to lightly press down until the insert begins to melt the plastic and moves into position. Simply pull the iron straight back up and out when the insert is in the proper place. Read more How do I replace the soldering iron tip with the insert installation tip? Unscrew the collar nut that holds the tip retaining sleeve Make sure the iron is turned off and cooled down. Turn the nut with the knurling counter clockwise to loosen until it's free. Take the nut off the iron by moving it toward tip end of the iron. Remove the retaining sleeve by pulling it towards the tip end of the iron. Remove the soldering tip which is over the ceramic heating element Simply slide the old tip off the ceramic heating core. Place the new insert installation tip over the heating element Guide the heating element into the 5/32" hole in the insert tip and position the tip as far down as it will go. Place the sleeve back over the tip and screw on the collar nut Place the retaining sleeve back over the wand. Bring the collar nut back over the sleeve and rotate the nut clockwise finger tight. Read more Why use a specific size of tip? It's important to pair the correct size of tip with the size of insert you are using. If the tip is too small for the insert, plastic will come back up inside the threads making it very difficult to turn your screw into the insert. Many times your part can be ruined because it's difficult to replace an insert if the surrounding plastic is deformed. We created these specific sizes because they are some of the most popular sizes and they are precision machined to be exact fits with just enough clearance that they don't pull the insert back out, but not so much clearance that plastic comes inside the threads. The right tool for this job requires the right size tip and this set has the most popular metric sizes. Common questions Where can I find inserts? Search for "Heat set inserts". It's best if you use the "conical" shaped inserts, those with a wider top than bottom. Those are the inserts designed for heat-set. How long are these tips? Total length on these tips is 1.6 inches or 40.6 mm. On a Hakko FX888D these tips reach 0.66" or 16.8 mm from the end of the collar. Spacing required underneath? Make the insert hole deeper than the insert itself because the insert is melting its way into the plastic and needs space to move. If the hole is not deep enough the plastic the insert is melting on its way down has nowhere to go. In the worst case scenario plastic may seep back into the center making it difficult to put a screw in or mound around the insert at the top edge. We try to make the hole at least an additional 1/3 to 1/2 as deep as the insert. What hole size should I use? In practice, you should either drill or design in holes that are about 90% of the width of the insert measured at the mid-point of the insert. If using heat set inserts, the width will be smallest at the bottom and largest at the top. Pick a point mid-way between these two and measure that width and that's a good starting point. Your 3D printer will probably not make perfect size holes, so you may need to experiment a bit to get the best bite without pushing plastic up, down, and around. Do these need to be cleaned? Once heated the beautiful shiny brass will darken. That's normal. If you happen to get plastic onto the tip you may be able to clear it by wiping on a wet rag or steel or brass wool. Acetone would chemically clean it but make sure the iron is not hot when you do that! Will this fit any Weller iron? These tips will not fit most Wellers. They will fit the Weller SP40KNUS that has a 1/4" barrel and set screw retention.
