The set covers a capacity range of 1\/8 inch to 3\/4 inch, with collets supplied in 1\/16-inch increments. Total runout (TIR) is rated at 0.0007 inches, providing the concentricity required for accurate milling operations. The set is handled by machinists and tool-and-die technicians working on vertical milling machines equipped with R8 spindles. All 11 collet sizes are included in a single package.\u003c\/p\u003e\n\u003cp\u003eThis collet set is suited for vertical knee mills and similar R8-spindle machines found in job shops, maintenance departments, and trade training environments. The full 11-piece range allows the operator to chuck a wide variety of end mills, drill bits, and round-shank tooling without changing collet systems. The 1\/16-inch size progression covers the most common shank diameters encountered in general milling work. At 7 pounds, the set is substantial enough for daily shop use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eR8 collet system compatible with R8-spindle vertical milling machines\u003c\/li\u003e\n  \u003cli\u003e11-piece set covering 1\/8 inch through 3\/4 inch in 1\/16-inch increments\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.0007 inches for consistent tool concentricity\u003c\/li\u003e\n  \u003cli\u003eSizes included: 1\/8, 3\/16, 1\/4, 5\/16, 3\/8, 7\/16, 1\/2, 9\/16, 5\/8, 11\/16, and 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003eComplete set reduces the need for individual collet sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or supplemental set for vertical milling machines equipped with an R8 spindle taper.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eR8 collets are installed and removed by a qualified machinist using the machine spindle drawbar. Power down and de-energize the milling machine before changing collets. Inspect each collet bore and taper for chips or damage before seating. Do not overtighten the drawbar beyond hand-snug plus a firm turn, as this can distort the collet bore and increase runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet System\u003c\/strong\u003e: R8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.1250 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.7500 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize Increments\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 231-0011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716048159026,"sku":"231-0011","price":198.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2e0854e5c5094b5f909f1c26c3b26d6.jpg?v=1788521569","url":"https:\/\/voomisupply.com\/products\/value-collection-231-0011-r8-collet-set-11-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
