Need to polish metal parts or remove tiny burrs? These stainless steel pins are perfect for your rotary or magnetic tumbler. This pack contains 1 kilogram of 304 stainless steel pins, each 0.7mm in diameter and 5mm long. They're magnetic, so they're easy to retrieve from your parts and tumbler. They work by constantly rubbing against the metal surfaces, deburring edges, polishing to a shine, and even cleaning out blind holes. They're extremely durable and can be reused thousands of times. Great for gunsmiths, jewelers, machinists, or anyone finishing metal components. Choose the pin size based on your part's material and detail size – thicker pins are for harder metals/heavier work. Comes in a handy bottle for storage. An essential consumable for a professional finish.
