What is the magnetic tumbler?

A magnetic tumbler is a specialized machine used for polishing and finishing jewelry and small metal items. It utilizes a magnetic field to create a rapid spinning motion, causing stainless steel pins to move in a toroidal (doughnut-shaped) pattern. This unique movement ensures that the pins effectively polish and clean intricate designs, crevices, and hard-to-reach areas of jewelry pieces, resulting in a bright and shiny finish in a relatively short time.

How to use the magnetic tumbler?

Using a magnetic tumbler involves the following steps:

  • Fill the bowl with stainless steel pins.
  • Add water and a suitable polishing compound or soap.
  • Place the jewelry pieces into the bowl.
  • Close the lid and set the timer for the desired duration, typically ranging from 15-30 minutes.
  • Start the machine. The magnetic field will initiate the rapid movement of the pins, polishing the jewelry.
  • Once the cycle completes, turn off the machine, remove the jewelry, rinse thoroughly, and dry.

How to select the magnetic tumbler?

When choosing a magnetic tumbler, consider the following factors:

  1. Size & Capacity: Depending on the volume of jewelry you work with, select a tumbler that fits your needs.
  2. Motor Quality: A durable motor that can run for extended periods without overheating is essential.
  3. Timer Features: Opt for tumblers with adjustable timers for flexibility.
  4. Brand Reputation: Trusted brands are likely to offer better quality and durability.
  5. Maintenance: Easy-to-clean models are more user-friendly.
  6. Price: Ensure you get value for your money by comparing prices and features.
