Stainless Steel Tumbling Media Pins - 0.047" Diameter, 0.255" Length (5 lb Pack)
The perfect non-fracturing and rust free rotary tumbling media to clean, polish, and deburr metals. Ideal for brass cases of all primer sizes. However, this media can be used on any metal with a hardness less than or equal to the 302/304 stainless steel used in these pins. Magnetized by the manufacturer allowing for easy floor pickup with a ceramic or rare earth magnet. The dimensions of these pins (0.047" diameter and 0.255" length) were specifically designed so that they would not become jammed in the flash hole or primer pocket of brass cartridges. The smaller 41 size pins have a tendency to get jammed sideways in the primer pocket. A standard 1 gallon rotary tumbler requires approximately 5 pounds of stainless pins to efficiently and quickly clean brass cases or metal parts. Made in the USA.
