Machined from steel, this collet accepts 3\/32 inch round shank tooling and features a 7\/16-20 drawbar thread for secure engagement with standard R8 drawbars. It holds a total indicator runout (TIR) of 0.0007 inches, supporting accurate, repeatable tool positioning across a range of light to medium milling operations. Machinists and toolroom technicians rely on collets like this for consistent grip and minimal tool deflection during cutting passes.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for manual and CNC knee mills, Bridgeport-style mills, and other machines with R8 spindle configurations. It is a practical choice for shops running 3\/32 inch end mills, drill bits, or other small-diameter round shank tooling. The R8 system is common in job shops, maintenance facilities, and vocational training environments where versatile toolholding is a daily requirement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/32 inch bore accepts standard round shank tooling of that diameter\u003c\/li\u003e\n  \u003cli\u003eR8 taper profile fits machines with R8 spindle receivers\u003c\/li\u003e\n  \u003cli\u003e7\/16-20 drawbar thread for compatibility with standard R8 drawbars\u003c\/li\u003e\n  \u003cli\u003e0.0007 inch TIR for accurate, low-runout tool holding\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated clamping cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or addition for milling machines equipped with R8 spindle tapers and 7\/16-20 drawbar threads.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians familiar with R8 toolholding systems. Power down and de-energize the machine spindle completely before inserting or removing collets. Insert the collet into the spindle bore, engage the drawbar threads by hand, and tighten the drawbar to secure the collet and tool — do not over-torque the drawbar as this can damage the collet or spindle bore. Inspect the collet bore and spindle taper for chips or debris before each use to maintain TIR performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Type\u003c\/strong\u003e: R8 Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrawbar Thread Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Indicator Runout (TIR)\u003c\/strong\u003e: 0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0275 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: 231-4706\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701702426930,"sku":"231-4706","price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/915702297aa940d731328f65c53af317.jpg?v=1788404038","url":"https:\/\/voomisupply.com\/products\/value-collection-231-4706-r8-round-collet-3-32-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
