These jump ring mandrels are straight, closely spaced diameters for winding coils and cutting consistent jump rings, whether you’re using a jump ring maker or coiling by hand. The smooth shafts feel solid in the hand so wire tracks evenly as you wrap and cut.

Features

Individual mandrels offered in a wide range of small diameters for fine to medium jump rings.
Straight, uniform shafts help wire coil evenly for consistent ring size and clean cuts.
Larger sizes are drilled through so coils can be slid off easily after winding.
Smaller diameters are supplied as solid mandrels for added strength at fine sizes.
Mandrels are sold individually so you can build or replace exactly the sizes you need.
Compatible with typical bench setups for hand winding or use with jump ring making tools.

Notes

The smallest mandrels (2.5–4.0 mm) are solid and best suited to very fine coils; larger diameters include a through-hole that can help when sliding off longer coils after cutting. Choose your size based on the finished inner diameter you need for your jump rings and the wire gauge you typically use.
