2.5 lb Stainless Steel Tumbling Media Pins, 0.039 Inch Diameter, 0.255 Inch Length

perfect!

Wow what a time saver. This will clean your brass cases in under an hour or if you give it 1.5 hours it will also clean the primer pockets as well as inside the case. There is nothing that compares and I wish I had have bought one a long time ago!! High, highly recommend getting one. No more cleaning the primer pocket, its now a thing of the past. As for longevity I havent had it that long. But given the design of it, I would expect it to last quite a while. Also like the hexagonal shape over a round tumbler. Seems to agitate the media and brass better. Also, the see through perspex container means I can see how bright they are without having to take the lid off. All in all, I highly recommend it.

Very consistent sizing top quality

I use these for tumbling brass. These are awesome as you can just clean them instead of throwing out corn cob media. They are an expensive initial investment, but if you reload often like I do worth it. These things are very very loud though. The reason I give three stars is I would buy an ultrasonic cleaner if I could do it over with the money. If you dont want to deal with the ultrasonic cleaner, this is definitely a lot easier to use as you just clean the tumbling media and the tumbler and thats it. Not need to worry about vibration rates or dilution ratio of your cleaner. Just throw it in and turn it on. So I think it is great for cleaning brass as it doesnt need to be perfect. If you want perfect, get an ultrasonic cleaner.

Very sharp edges. Not able to use on soft metals until I can fix that.

Wet tumbling brass for reloading in a harbor freight 5lbs vibrating tumbler. An hour with water and dawn dish soap and the brass looks better than it did new.

Best price per lb. Functions as should, and cleans 9mm, 5.56 and .308 brass like new in 3 hours

I use the pins along with a wet tumbler to clean rifle and pistol brass.

These are true stainless pins, perfect for case cleaning in my tumbler

I used it to clean and polish coins and it worked great, I just added soap and water in a rotary tumbler and left it for a few hours and it came out perfect. Only thing is I highly recommend buying a magnet with a “switch” to “turn” it off to move and collect/separate the material because they really liked sticking to the wet coins because of how small they are.
