Magnetic Tumbling Pins - 0.5 x 5 mm

These premium Japanese-made stainless steel pins are the most common size used for general-purpose magnetic tumbling of jewelry. Measuring 0.5 mm in diameter and 5.0 mm in length, they provide the perfect balance between aggressive burnishing and the ability to reach into small details. They are made from high-quality 304 stainless steel to resist rust and maintain their sharp, effective edges over thousands of polishing cycles. These pins are essential for achieving a high-luster, work-hardened finish on everything from simple wedding bands to complex multi-part jewelry assemblies.
