Hollow Needles for Desoldering

A set of 8 handle, variuos diameter: 

0.8, 1.0, 1.2, 1.4, 1.6, 1.4, 1.6 and 2.0 mm.

The Hollow needles made of stainless steel, it is not sticking, use the pinhole penetration component pin, heated with a soldering iron, a slight rotation to the component lead and copper foil separation

The needle is used for hardware engineer to desolder the Electronic components(e.g. DIP components)from PCB , Because the needle is used with special stainless steel , the needle will not be pasted Flux.
