Mandrels for Jewerly-Making

A mandrel is a metalsmithing tool used to size and shape many types of metal and wire. Mandrels are typically used with a vise and a hammer or mallet to properly shape metal for jewelry-making. Mandrels come in all different shapes, sizes and materials, but are commonly made of steel, aluminum, wood or plastic. At Fire Mountain Gems and Beads, we have a wide variety of mandrels to choose from to fit your beading and jewelry-making needs.

Bezel-Forming Mandrels


Bezel-forming mandrels are ideal for when you need to create shaped bezels and jumprings. Our selection of bezel-forming mandrels are made of steel, and are available in the following shapes: triangle, square, round and hexagonal.

Jump Ring Mandrels


Jump ring mandrels feature distinct notches to assist in creating exact sizes of jump rings. Our inventory of jump ring mandrels have a foam cushion handle to provide a comfortable, secure grip without the need for a vise.

Ring Mandrels


A ring mandrel is the go-to tool for adjusting the size of a ring or simply measuring ring size. At Fire Mountain Gems and Beads, we carry plastic and aluminum mandrels that are ideal for measuring a ring's size, and we also carry a carbon steel mandrel for adjusting a ring's size. The plastic mandrel can also be used to shape polymer clay creations.

Bracelet Mandrel


Similar to a ring mandrel, but featuring a larger diameter, a bracelet mandrel is a tool for shaping bracelets or adjusting the size of a bracelet. Fire Mountain Gems and Beads has developed a bracelet mandrel that is perfect for creating round bangles with its round shape and diameter markings.

Bangle Gauge Mandrel


This professional-looking, cast aluminum bracelet mandrel with plastic base has clearly etched increments to accurately measure round bangles. The circumference tapers from 6.67 inches to 9.47 inches to provide a range of sizes for customer wrists. This mandrel works best with soft metals such as gold, silver, copper and brass.
