{"product_id":"collet-blocks-hex-square-er-40","title":"Collet Block Set (Hex\/Square), ER-40","description":"\u003cp\u003eA collet block is a precision work holding device designed to securely grip and position cylindrical or hexagonal workpieces. Unlike traditional vises that clamp with flat jaws, collet blocks utilize a collet – a slotted sleeve with a tapered outer surface – that collapses uniformly around the workpiece when tightened. This provides a concentric and consistent grip, minimizing the risk of distortion or damage, particularly when working with delicate or thin-walled materials.\u003c\/p\u003e\n\u003cp\u003eThe collet block itself is typically a hardened steel block, often square or hexagonal, with a precision-machined bore to accommodate the collet. The combination of the precision collet and the stable block creates a rigid and accurate platform for a wide range of machining operations.\u003c\/p\u003e\n\u003cp\u003eThis SQUARE collet block provides easy indexing for 2 and 4 divisions.\u003cbr\u003eThe collet block is 1.75\" square and the body is 3.2\" long.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThis HEXAGONAL collet block provides easy indexing for 3 and 6 divisions.\u003cbr\u003eThe collet block is 1.75\" across the flats and the body is 3.2\" long.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eER-40 collets have a have a clamping range of 1\/8\" to 1\" (3.0 mm to 26.0 mm).\u003c\/p\u003e\n\u003cp\u003eThis spanner wrench fits ER-40 collet nuts (55-62mm). \u003c\/p\u003e","brand":"LittleMachineShop.com","offers":[{"title":"Default Title","offer_id":52285841014965,"sku":"6845","price":99.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0671\/3157\/2405\/files\/6845.jpg?v=1772065354","url":"https:\/\/littlemachineshop.com\/products\/collet-blocks-hex-square-er-40","provider":"LittleMachineShop.com","version":"1.0","type":"link"}
