I used a Dremel 220 drill press along with a Weller SP40NKUS 40W soldering iron to make this heat set nut insert tool. I also purchased the brass inserts for the soldering iron from Amazon here https://www.amazon.com/dp/B08B17VQLD?psc=1&ref=ppx_yo2_dt_b_product_details
I made a quick video that explains the tool here https://youtu.be/uIZoQaaNZiY
Enjoy!
