This collet functions as a small, precision 3-jaw chuck that fits into a specially designed tapered adapter within the headstock. A drawbar threads into the collet's backside, drawing it into the adapter, which causes the jaws to close and securely grip the part to be machined. The collet is designed to accommodate a small range of diameters, approximately ±.001″ (.02mm), ensuring precise part mounting.\u003c\/p\u003e\n\u003cp\u003eWW collets are distinct from milling collets due to their through-hole design, allowing stock with a maximum diameter of 3\/16″ or 4.5mm to pass entirely through. Collets larger than this diameter are referred to as \"pot\" chucks and are not bored through, being only .260″ deep. The collet's maximum runout is .002″ or less, and when the WW collet adapter is properly trued, it operates with optimal accuracy.\u003c\/p\u003e\n\u003cp\u003eSherline collets are manufactured to standard WW specifications, with a shank diameter of .312-.313 and a .275-40 thread. It is crucial to verify compatibility with other manufacturers' WW collets to ensure they fit the Sherline adapter. The collets are available in inch sizes by 64ths of an inch from 1\/64″ to 5\/16″ and in metric sizes from .3 mm to 8.0 mm by .1 mm increments.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cbutton class=\"expandable-content__toggle\" aria-expanded=\"false\" aria-controls=\"main-description\"\u003e\u003cspan class=\"expandable-content__toggle-icon\"\u003e\u003c\/span\u003e\u003cspan class=\"expandable-content__toggle-text\" data-view-more=\"View more\" data-view-less=\"View less\"\u003eView more\u003c\/span\u003e\u003c\/button\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cdiv class=\"card details_product\"\u003e\n\u003cbutton class=\"card__collapsible-button\" data-action=\"toggle-collapsible\" aria-expanded=\"false\" aria-controls=\"unique-tab-2\"\u003e\r\n\u003cspan class=\"card__title heading h3\"\u003eWhat's Included\u003c\/span\u003e\r\n\u003cspan\u003e\r\n\u003csvg focusable=\"false\" class=\"icon icon--arrow-bottom\" viewbox=\"0 0 12 8\" role=\"presentation\"\u003e\r\n\u003cpath stroke=\"currentColor\" stroke-width=\"2\" d=\"M10 2L6 6 2 2\" fill=\"none\" stroke-linecap=\"square\"\u003e\u003c\/path\u003e\r\n\u003c\/svg\u003e\r\n\u003c\/span\u003e\r\n\u003c\/button\u003e\r\n\u003cdiv id=\"unique-tab-2\" class=\"card__collapsible\"\u003e\r\n\u003cdiv class=\"card__collapsible-content\"\u003e\r\n\u003cdiv class=\"rte text--pull\"\u003e\r\n\u003cul\u003e\n\u003cli\u003e1x Sherline 3\/16\" (.1875) WW Collet\u003c\/li\u003e\n\u003c\/ul\u003e\n\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv class=\"card details_product\"\u003e\n\u003cbutton class=\"card__collapsible-button\" data-action=\"toggle-collapsible\" aria-expanded=\"false\" aria-controls=\"unique-tab-3\"\u003e\r\n\u003cspan class=\"card__title heading h3\"\u003eDimensions\u003c\/span\u003e\r\n\u003cspan\u003e\r\n\u003csvg focusable=\"false\" class=\"icon icon--arrow-bottom\" viewbox=\"0 0 12 8\" role=\"presentation\"\u003e\r\n\u003cpath stroke=\"currentColor\" stroke-width=\"2\" d=\"M10 2L6 6 2 2\" fill=\"none\" stroke-linecap=\"square\"\u003e\u003c\/path\u003e\r\n\u003c\/svg\u003e\r\n\u003c\/span\u003e\r\n\u003c\/button\u003e\r\n\u003cdiv id=\"unique-tab-3\" class=\"card__collapsible\"\u003e\r\n\u003cdiv class=\"card__collapsible-content\"\u003e\r\n\u003cdiv class=\"rte text--pull\"\u003e\r\n\u003cul\u003e\n\u003cli\u003e3\/16\" (0.1875\")\u003c\/li\u003e\n\u003c\/ul\u003e\n\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv class=\"card details_product\"\u003e\n\u003cbutton class=\"card__collapsible-button\" data-action=\"toggle-collapsible\" aria-expanded=\"false\" aria-controls=\"unique-tab-4\"\u003e\r\n\u003cspan class=\"card__title heading h3\"\u003eLinks\u003c\/span\u003e\r\n\u003cspan\u003e\r\n\u003csvg focusable=\"false\" class=\"icon icon--arrow-bottom\" viewbox=\"0 0 12 8\" role=\"presentation\"\u003e\r\n\u003cpath stroke=\"currentColor\" stroke-width=\"2\" d=\"M10 2L6 6 2 2\" fill=\"none\" stroke-linecap=\"square\"\u003e\u003c\/path\u003e\r\n\u003c\/svg\u003e\r\n\u003c\/span\u003e\r\n\u003c\/button\u003e\r\n\u003cdiv id=\"unique-tab-4\" class=\"card__collapsible\"\u003e\r\n\u003cdiv class=\"card__collapsible-content\"\u003e\r\n\u003cdiv class=\"rte text--pull\"\u003e\r\n\n\u003cp\u003e\u003cstrong\u003eZIP Files\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.robotshop.com\/media\/S\/She\/RB-She-605\/zip\/sherline_3_16_1875_ww_collet_large_collets.zip\" target=\"_blank\"\u003eSherline 3\/16\" (.1875) WW Collet -
