Steel Brush cleaning pin

For cleaning the connection areas on circuit boards, cleaning contacts of all kinds, removing residues on metal templates.

In plastic modelling used to sand over applied glue on models.
When in use, only the tip of the glass fibre should come out of the pin(sanding surface). After use, clean the working area. Glass fibers can break and could penetrate the skin.

Sands a bit harder as Brass Brush.
