Precision Sanding for Jewelry, Models \u0026amp; Fine Craft — 3‑Piece Split Spindle Mandrel Set with 2.35mm Shank.\u003c\/strong\u003e\n            Reach the intricate, hard‑to‑access areas that standard sanding tools can't touch. This set includes three distinct split mandrel profiles—straight, slim, and tapered—giving you the flexibility to match the tool to the contour you're working on. Each mandrel accepts a strip of emery paper or wet\/dry abrasive that is simply threaded through the slot and wound around the shaft. A standard 2.35mm shank fits most pendant motors, micro motors, and hobby drills. Ideal for jewelry polishing, watch repair, model making, deburring, and any task requiring controlled, detailed sanding in confined spaces.\n        \u003c\/div\u003e\n\n        \u003c!-- 产品特点（h2 + h3结构） --\u003e\n        \u003ch2 class=\"homediyer-section-title\"\u003e⚙️ Key Features of the 3‑Piece Split Spindle Set\u003c\/h2\u003e\n        \u003cdiv class=\"homediyer-feature-list\"\u003e\n            \u003cdiv class=\"homediyer-feature-item\"\u003e\n                \u003cdiv class=\"feature-emoji\"\u003e📐\u003c\/div\u003e\n                \u003cdiv class=\"feature-text\"\u003e\n                    \u003ch3\u003eThree Mandrel Profiles: Straight, Slim \u0026amp; Tapered\u003c\/h3\u003e\n                    \u003cp\u003eStraight for flat surfaces and consistent diameters.

Wind the paper so that the rotation of the tool tightens the paper, not loosens it. When the outer layer becomes worn, simply tear it off to reveal a fresh layer of abrasive underneath—no need to re‑thread.\n        \u003c\/div\u003e\n        \u003cdiv style=\"height: 8px;\"\u003e\u003c\/div\u003e\n    \u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003c\/body\u003e","brand":"HomeDIYer","offers":[{"title":"Default Title","offer_id":52210861998354,"sku":"WWQ0064","price":2.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/8936\/1682\/files\/Picture1of5_7b464123-096a-4154-90f4-f288b3603cf6.jpg?v=1777008378","url":"https:\/\/homediyer.com\/products\/sandpaper-mandrel-jewellery-polish","provider":"HomeDIYer","version":"1.0","type":"link"}
