Wet tumblers use stainless steel media. The preferred media is 0.040 diameter by .250 long, 300-series stainless steel pins. The pins are smooth; they will not erode or work-harden the brass, and they can be reused indefinitely.his month, we'll take a look at wet tumbling with stainless steel media.
