Compatible with a Foredom No. 30 style handpiece and flex shaft machine, this system lets you produce jump rings from soft, non-ferrous jewelry wire including gold, copper, and silver.\u003c\/p\u003e\n\u003cp\u003eWire as thick as 13 gauge (1.85 mm) can be used, and the inside diameter of finished rings ranges from 2.5 mm to 12 mm. Outside diameter will vary based on wire diameter. The most commonly used wire gauge in the jewelry industry for jump ring production is 0.8 mm – 1.0 mm.\u003c\/p\u003e\n\u003cp\u003eThe Quad Jump Ringer differs from the Durston Complete Jump Ringer in several key ways. It does not include a stand and instead uses a simple vise or bench-mounted hand coiler, making it a more economical option. It includes the same 20 mandrels and uses the same handpiece holder and high speed steel saw blade. A notable feature is the \u003cstrong\u003eQuad Coil Holder\u003c\/strong\u003e — a 4-sided design that provides more precise angles for holding specific jump ring sizes.\u003c\/p\u003e\n\u003cp\u003eThe included mandrel set ranges from 2.5 mm (smallest) to 12 mm (largest) in 1\/2 mm increments. Note that the three smallest mandrels — 2.5 mm, 3 mm, and 4 mm — are \u003cem\u003enot\u003c\/em\u003e drilled with holes. All other mandrels in the set are drilled with holes.\u003c\/p\u003e\n\u003cp\u003eThe Durston Quad Jump Ringer requires a Foredom No. 30 type handpiece and flex shaft machine.
