The set covers a capacity range from 0.125 inches to 0.875 inches in 1\/8-inch increments, giving machinists a complete range of common end mill and cutter shank sizes in a single kit. A 15-piece storage rack is included to keep collets organized and protected at the workstation. Weighing 11 pounds, the set is substantial enough for production-environment demands. Machinists, toolroom technicians, and machine shop operators are the primary installers and users of this tooling.\u003c\/p\u003e\n\u003cp\u003eThis collet set is suited for manual vertical milling operations in job shops, production machining environments, and vocational training facilities. The R8 taper is the most widely used spindle interface on knee mills found in small and mid-size machine shops across North America. With collets sized at 1\/8, 3\/16, 1\/4, 5\/16, 3\/8, 7\/16, 1\/2, 9\/16, 5\/8, 11\/16, 3\/4, 13\/16, and 7\/8 inch, the set addresses virtually every standard end mill shank diameter encountered in day-to-day milling work. The included rack keeps all 13 collets accessible and prevents damage to the precision-ground bores between uses.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eR8 collet system compatible with Bridgeport-style knee mills and other R8-spindle machines\u003c\/li\u003e\n  \u003cli\u003e13 collets spanning 0.125 to 0.875 inches in 1\/8-inch increments\u003c\/li\u003e\n  \u003cli\u003eCovers all 13 standard sizes: 1\/8, 3\/16, 1\/4, 5\/16, 3\/8, 7\/16, 1\/2, 9\/16, 5\/8, 11\/16, 3\/4, 13\/16, and 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003eIncludes a 15-piece storage rack for organized bench or toolroom storage\u003c\/li\u003e\n  \u003cli\u003eSet weight of 11 pounds reflects solid, production-grade construction\u003c\/li\u003e\n  \u003cli\u003eSold as a complete kit — no individual collet sourcing required for standard shank sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with R8-spindle milling machines.

Ensure the spindle bore and collet taper are clean and free of chips or debris before seating the collet. Use the correct drawbar wrench to tighten the drawbar to adequate engagement; overtightening can distort the collet bore and undertightening risks tool pullout during cutting. Inspect collet bores regularly for wear or out-of-round conditions that can affect 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: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize Increments\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Sizes\u003c\/strong\u003e: 1\/8, 3\/16, 1\/4, 5\/16, 3\/8, 7\/16, 1\/2, 9\/16, 5\/8, 11\/16, 3\/4, 13\/16, 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 15-piece storage rack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11 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: 231-2113\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697222811954,"sku":"231-2113","price":187.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40c410a96784ac710b24826a6a9ebac3.jpg?v=1788350744","url":"https:\/\/voomisupply.com\/products\/value-collection-231-2113-r8-collet-set-13-pc-1-8-7-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
