Adapter Mỏ Hàn Cổ Euro 43mm (Ép Ốc Ren)

The adapter has an inner diameter of 16 mm and is compatible with my cheap chinese JCB soldering iron. It also fits the Proxxon drilling and milling bench BFB 2000 with its outer diameter of 43mm. 

This means it can fit any drill stand with a euro neck, such as Wabeco, KWB, Wolfcraft and even the most low-cost soldering irons from the ali express universe.

If your handpiece is thicker than 16mm somewhere along the line, there is a second file that is split down the middle.
 

My primary use of this tool is to apply threaded inserts.
