Selecting the Right Bead Reamer

by Anne Marie Hunter, Exclusively for Fire Mountain Gems and Beads®

It's been said that a good bead reamer can be your best friend.

An essential tool for jewelry designers, a bead reamer is a pointed, round file that is used to either smooth the edges of the drill-hole in a bead, or to enlarge or straighten the hole itself. A reamer allows you to use beads that might not seem usable because of small hole size, sharp edges, irregularity or burrs. Additionally, it's important to smooth the rough edges on a bead as they will wear or abrade the wire or cord of your design. And, a bead reamer helps the designer achieve smooth centers and larger bead holes without damaging the beads.

Bead reamers have distinctive qualities and selecting the correct tool for a particular bead is important. Fire Mountain Gems and Beads® offers an excellent selection of bead reamers and learning more about choosing the correct reamer can contribute to design success for jewelry and bead artists.

The following are uses for individual bead reamers:

Extra-Fine Pearl Reamer
According to Esther, lead jewelry production specialist, ''Pearls are softer and the fluted, double helix pattern of this extra fine pearl reamer allows you to increase or smooth the pearl's drill-hole size.'' This reamer is ideal for freshwater pearls because they are fragile and is most effective when using an easy twisting motion. Made of a stainless steel alloy and designed with a special S-shaped cross section, this reamer is resistant to breakage.

4-piece set includes: 1.8mm yellow, 3.0mm red, 4.8mm green and 5.0mm blue

Diamond Dust-Coated Set
''The reamers in this four-piece set function more as files,'' notes Esther. ''They work really well for gemstone beads to increase the drill-hole size or remove unwanted burrs from the hole. These reamers remove a small amount of material at a time from harder gemstone surfaces, to reduce the risk of damage. They're a good choice for opening the end of a bead that has an incomplete or half-finished hole.'' Encrusted with industrial-grade diamond dust and available in several shapes and widths, these steel tools work well for stones that have very small drill-holes or unwanted burrs.

Diamond-Coated Wire
This reamer will evenly increase drill-hole size to desired size, starting from 1mm. Because of the diamond coating, this reamer is ideal for harder gemstones or beads. It can be used on most stones, glass and ceramic. Reamer size is 1mm wide.

4-piece interchangeable set includes: one long round (80 mm long, 3.2 mm wide at top of file), one flat (5.7 wide X 1.4mm thick at the top. Tapers down to .5 mm at end), one short round (2 mm thick at top of file) and one arrow (5.8 mm thick).

Interchangeable 4-Piece Set
Terrific reamers for gemstones, the diamond-coated tips in this set enlarge and straighten the drill-holes and also smooth any surfaces or rough edges around the holes. These reamers are excellent for polymer clay and wood beads, also. Often wood beads have loose fibers or splinters in the hole that will snag cord, such as satin, when stringing.

Diamond-Coated Bead Reamer
An essential bead reamer for many of the most common reaming needs, use it to both increase the diameter or straighten holes. Keep it at your fingertips for use with acrylic beads, art clay or bisque beads. 1.8 mm wide.

For beads 8mm or smaller, plastic-tipped tweezers, will hold the beads in place when working with a reamer. In addition, it's recommended to ream your beads and stones while they're wet or in a bowl of water. Water acts as a lubricant to protect beads from chipping or cracking as a result of friction heat produced by these tools. Water not only sustains the component from damage, it reduces wear and tear on the reamer itself. For your safety, always wear eye protection when using pearl or bead reamers.

Finally, Esther offers excellent advice for effectively using a reamer. ''Use the smallest tip to start with because the tips are specifically meant to take a little at a time. Don't force the reamer to do the work, but let the tool do the work for you, so the beads aren't damaged.''
