The thumb-mounted turning base accepts any of the four included mandrels via a threaded end connection — slip your thumb through the hole, grip the handle, and begin coiling. Once your coil is complete, use a jeweler's saw and bench pin (not included) to cut the coils into individual jump rings. This is the small mandrel version, covering four commonly used diameters: 4mm, 6mm, 7mm, and 8mm.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThumb-mounted turning base for easy, controlled wire coiling\u003c\/li\u003e\n\u003cli\u003eThreaded mandrel ends screw securely into the turning base\u003c\/li\u003e\n\u003cli\u003eIncludes four mandrels in four distinct diameters: 4mm, 6mm, 7mm, and 8mm\u003c\/li\u003e\n\u003cli\u003eEach mandrel is 4 inches long\u003c\/li\u003e\n\u003cli\u003eProduces uniform coils that can be cut into jump rings with a jeweler's saw and bench pin\u003c\/li\u003e\n\u003cli\u003eCompact, small-diameter version ideal for smaller jump ring sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eMandrel Diameters Included\u003c\/th\u003e\n\u003ctd\u003e4mm, 6mm, 7mm, 8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMandrel Length\u003c\/th\u003e\n\u003ctd\u003e4 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMandrel Connection\u003c\/th\u003e\n\u003ctd\u003eThreaded end\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eQuantity of Mandrels\u003c\/th\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 thumb-mounted turning base\u003c\/li\u003e\n\u003cli\u003e4 mandrels (4mm, 6mm, 7mm, and 8mm diameter)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cp\u003eA jeweler's saw and bench pin are required to cut finished coils into jump rings and are \u003cstrong\u003enot included\u003c\/strong\u003e with this tool.\u003c\/p\u003e","brand":"Value Line","offers":[{"title":"Default Title","offer_id":43581015261398,"sku":"143.091","price":15.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/143.091NEW_thumb_21aa4246-6f76-4cd5-97ae-82ef950ffa81.jpg?v=1787088925","url":"https:\/\/www.ottofrei.com\/ja\/products\/simple-jump-ring-maker-4-mandrels-4mm-6mm-7mm-8mm","provider":"Otto Frei","version":"1.0","type":"link"}
