The set covers a capacity range from 1\/16 inch (0.0625 inch) to 7\/8 inch (0.8750 inch) in 1\/32-inch increments, giving machinists and toolroom technicians full coverage for common end mill, drill, and toolholder shank sizes. Total indicated runout (TIR) is rated at 0.0007 inch, supporting accurate material removal and repeatable tool positioning across the full range.\u003c\/p\u003e\u003cp\u003eThis collet set is suited for job shops, maintenance machine shops, and production toolrooms running R8-spindle knee mills. The 27-piece range eliminates the need to source individual collet sizes separately, making it practical for shops that run varied tooling on a single machine. Two 14-piece storage racks are included, keeping collets organized and protected when not in use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e27-piece set covering 1\/16 inch to 7\/8 inch in 1\/32-inch increments\u003c\/li\u003e\n\u003cli\u003eR8 collet system for compatibility with R8-spindle milling machines\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0007 inch for consistent tool concentricity\u003c\/li\u003e\n\u003cli\u003eIncludes two 14-piece storage racks for organized bench storage\u003c\/li\u003e\n\u003cli\u003eFull fractional inch size range eliminates gap coverage in common tooling diameters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or supplemental set for milling machines equipped with an R8 spindle taper.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eR8 collets are installed and removed by a qualified machinist or toolroom technician. Power down and lock out the mill spindle drive before changing collets. Use the appropriate drawbar wrench to seat and secure the collet fully in the spindle taper — an improperly seated collet can cause tool pullout under load. Inspect collet bore and taper surfaces for chips or burrs before each installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 1\/16 inch (0.0625 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 7\/8 inch (0.8750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize Increments\u003c\/strong\u003e: 1\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0007 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Accessories\u003c\/strong\u003e: Two 14-piece storage racks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 19.32 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 231-2127\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51713787560242,"sku":"231-2127","price":465.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d472fa71f8310fc9e52602e50cceb7f.jpg?v=1788495165","url":"https:\/\/voomisupply.com\/products\/value-collection-231-2127-r8-collet-set-27-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
