Frankford Arsenal Stainless Steel Tumbling Media 2 lbs 1mm x 7mm Magnetic Pins

The Frankford Arsenal Stainless Steel Tumbling Media is a 2 lb pack of fine magnetic stainless steel pins designed to restore spent brass cartridge cases to a polished, like-new finish inside a rotary tumbler. Each pin measures 1mm x 7mm, small enough to reach inside case necks and primer pockets where conventional corncob or walnut shell media cannot access.

This media is sized specifically for the Frankford Arsenal Rotary Tumbler Lite, providing the recommended fill of stainless pins to keep that tumbler operating at peak efficiency. The magnetic pins cling together for clean handling, and the stainless construction helps prevent rust and corrosion so the media stays ready for the next batch of brass.

Once tumbling is complete, the magnetic pins can be quickly separated from cleaned cases using a magnetic wand or media separator, leaving you with a tub of bright, ready-to-load brass. The 1mm x 7mm pin profile scrubs the inside of the case body, the case neck, and the primer pocket, removing residual case lube, carbon, and surface tarnish. Stainless steel resists corrosion and stands up to repeated tumbling sessions without breaking down.

Whether you are processing range brass or reclaiming fired casings, the Frankford Arsenal Stainless Steel Tumbling Media is a reusable cleaning solution that pairs directly with the Rotary Tumbler Lite for a complete brass-polishing setup.
