The Variable Speed Amalgamator differs from its cousin, the Speed Stir, because of its options in speed settings: while the Speed Stir is set at 4,400 rpm for a reliably constant speed for all operations, the Variable Speed lets users choose to minimize cleaning time or work gently on certain material tools. It utilizes the same vibration-absorbing benefits as the Speed Stire, along with the protective smoke cover, universal arm design, and durable arms.
