The set covers a capacity range of 2mm to 20mm in 1mm increments, giving machinists and tool-room technicians continuous size coverage across common end mill and cutter shank diameters. Each collet in the set follows the R8 standard for positive drive and concentricity. The complete set weighs 14.75 pounds and ships as a single package quantity. It is suited for production shops, job shops, and maintenance departments running manual or CNC knee mills with R8 spindles.\u003c\/p\u003e\n\u003cp\u003eThis collet set is used in machine shop environments where R8-spindle vertical milling machines are in service. Common install scenarios include outfitting a new mill, replacing worn or damaged individual collets as a complete set, or standardizing toolholding across a shop floor. The 1mm size increment ensures that a correctly sized collet is available for virtually every standard metric shank diameter from 2mm through 20mm. The included two 14-piece rack organizers keep the full set stored and accessible at the machine.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eR8 collet system for direct spindle compatibility with R8-taper milling machines\u003c\/li\u003e\n  \u003cli\u003e19 collets covering 2mm to 20mm capacity in 1mm increments\u003c\/li\u003e\n  \u003cli\u003eComplete metric size range eliminates the need for reducer bushings on standard shank sizes\u003c\/li\u003e\n  \u003cli\u003eIncludes two 14-piece storage racks for organized bench or cabinet storage\u003c\/li\u003e\n  \u003cli\u003eSingle-package set at 14.75 pounds — ready to put directly into service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with vertical milling machines equipped with an R8 spindle taper, which is the standard spindle format found on a wide range of manual knee mills and light CNC knee-style mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eR8 collets are installed and removed by a licensed or trained machinist using the appropriate drawbar wrench — power down and de-energize the spindle drive before any collet change. Ensure the collet bore and spindle taper are clean and free of chips or coolant residue before seating. Never exceed the collet manufacturer's rated clamping torque on the drawbar, and inspect each collet for wear or cracking before use.\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: 19\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 2mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 20mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize Increments\u003c\/strong\u003e: 1mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Sizes (mm)\u003c\/strong\u003e: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Two 14-piece storage racks\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 14.75 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: 231-2119\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700159906098,"sku":"231-2119","price":445.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/744fe50de49221e4d8e1002a3881d2e2.jpg?v=1788386915","url":"https:\/\/voomisupply.com\/products\/value-collection-231-2119-r8-collet-set-19-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
