{"product_id":"durston-1309-complete-jump-ringer","title":"Durston 1309 The Complete Jump Ringer","description":"\u003cp\u003eThe Durston 1309 Complete Jump Ringer is a bench-mounted jump ring making machine designed for use with a Foredom No. 30 style handpiece and a flex shaft machine. It allows rapid, repeatable production of jump rings from soft non-ferrous jewelry wire, with precise control over ring size and consistency. As the coil builds and the saw begins its steady cut, finished rings collect in a clean, predictable rhythm.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for mass production of jump rings from soft non-ferrous wire\u003c\/li\u003e\n\u003cli\u003eUpdated base-mounted coil holder for improved stability\u003c\/li\u003e\n\u003cli\u003eSafety coil winder can be positioned freely on the workbench\u003c\/li\u003e\n\u003cli\u003eExtended mandrel length allows longer coils and higher output per run\u003c\/li\u003e\n\u003cli\u003eHigh stem design provides increased hand clearance and full 360° positioning\u003c\/li\u003e\n\u003cli\u003eIncludes a comprehensive set of mandrels for a wide range of ring sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum Wire Size\u003c\/th\u003e\n\u003ctd\u003e13 gauge (1.85 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMandrel Size Range\u003c\/th\u003e\n\u003ctd\u003e2.0–12.0 mm inside diameter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMandrel Increments\u003c\/th\u003e\n\u003ctd\u003e0.5 mm steps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMandrel Length\u003c\/th\u003e\n\u003ctd\u003e4-3\/4 in (120.7 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible Materials\u003c\/th\u003e\n\u003ctd\u003eGold, silver, copper and other soft non-ferrous wires\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufactured In\u003c\/th\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eDurston\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWhat’s Included\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eItem\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMandrels\u003c\/td\u003e\n\u003ctd\u003e21 mandrels, 2.0–12.0 mm in 0.5 mm sizes (2.0, 2.5, 3.0, 4.0 mm undrilled; all others drilled)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoil Holder\u003c\/td\u003e\n\u003ctd\u003e2-sided coil holder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSaw Blade\u003c\/td\u003e\n\u003ctd\u003e1-1\/4\" high-speed steel blade\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSaw Blade Mandrel\u003c\/td\u003e\n\u003ctd\u003eIncluded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHandpiece Holder\u003c\/td\u003e\n\u003ctd\u003eIncluded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoil Winder\u003c\/td\u003e\n\u003ctd\u003eWith keyless chuck\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHex Keys\u003c\/td\u003e\n\u003ctd\u003eSet of 3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eFor use with a Foredom No. 30 type handpiece powered by a flex shaft machine.
