Review on 🔥 Efficient Heat-Set Insert Installation Tip for #4-40 and M5 Inserts: Compatible with Hakko FX-888D and Weller Irons (SP40NUS) for Seamless Connection of 3D Printed Parts by Brandon Plowden

I bought it for M5x0.8 inserts and this tip doesn't fit. I measured it and it's about 4.5mm which is perfect for the M5x0.5 but the M5x0.8 has a 4.2mm hole and doesn't fit the tip. The description should reflect actual dimensions. *UPDATE* Changed top from 3 to 4: I returned and forgot the item for the above reason. Time has passed and yesterday I received a package from the seller with an 'updated/corrected' version that fits M5x0.8 perfectly (which is 3.95mm). I was surprised the seller sent it but it was a good surprise. Not many sellers will respond to this.
