The Duplex Quick Change Handpiece is a versatile and efficient tool for jeweleries and hobbyists. It features a duplex spring mechanism for quick and easy burr changes. The handpiece is lightweight and ergonomic, weighing only 0.4 lbs and measuring 12 x 1.25 x 1.25 inches, making it comfortable to use for extended periods.

Jewelers often employ the #18D Foredom Handpiece, a Quick Change Handpiece specifically designed for use with 3/32" (2.35mm) burs. This handpiece allows for quick accessory changes with just a press lever action. It boasts a slim grip and pre-lubricated ball bearings, eliminating the need for additional lubrication. However, it's important to note that the Duplex springs in this handpiece can be prone to breakage. Therefore, we recommend that only experienced users of flex shaft tools, especially those whose work necessitates added flexibility, consider purchasing this style of handpiece. For most users, the "straight" handpiece remains the preferable solution.
