Designed for R8-spindle milling machines, this set gives machinists and toolroom technicians a full spread of collet sizes in a single purchase. Total indicated runout (TIR) is held to 0.0007 inch, supporting accurate milling, drilling, and light boring operations. The set is suited for job shops, maintenance facilities, and vocational training environments where a broad collet selection is needed without sourcing individual sizes.\u003c\/p\u003e\u003cp\u003eThis collet set is intended for use with R8-spindle Bridgeport-style vertical knee mills and compatible manual milling machines commonly found in machine shops, maintenance departments, and fabrication facilities. All 25 collet sizes are included in one package, covering the full 1\/32-inch step progression from 1\/8 inch through 7\/8 inch. This makes the set practical for shops running a variety of end mill shank sizes, drill shanks, and boring bar shanks without needing to stock individual collets separately.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eR8 collet system — compatible with R8-spindle milling machines\u003c\/li\u003e\n\u003cli\u003e25 pieces covering 1\/8 inch to 7\/8 inch in 1\/32-inch increments\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0007 inch for consistent tool runout control\u003c\/li\u003e\n\u003cli\u003eFull size progression: 1\/8, 5\/32, 3\/16, 7\/32, 1\/4, 9\/32, 5\/16, 11\/32, 3\/8, 13\/32, 7\/16, 15\/32, 1\/2, 17\/32, 9\/16, 19\/32, 5\/8, 21\/32, 11\/16, 23\/32, 3\/4, 25\/32, 13\/16, 27\/32, 7\/8 inch\u003c\/li\u003e\n\u003cli\u003eSingle-purchase solution eliminates the need to source collets individually\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with R8-spindle milling machines.

Power down and lock out the milling machine spindle before changing collets. Use the correct drawbar wrench for the machine spindle — never overtighten the drawbar, as this can damage the collet or spindle taper. Inspect each collet bore and taper for chips or burrs before seating a tool.\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: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 1\/8 inch (0.1250 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 15 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: 231-0025\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694082392370,"sku":"231-0025","price":451.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a35151c24e66dbb36878e173120a2792.jpg?v=1788319998","url":"https:\/\/voomisupply.com\/products\/value-collection-231-0025-r8-collet-set-25-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
