The collet holds round workpieces with a bore size of 26.50mm and delivers a total indicator runout (TIR) of 0.015mm, providing consistent concentricity for turning, milling, and grinding operations. The internal thread is 1.041 inches-24 and the external thread is 1.242 inches-20, conforming to standard 5C geometry. Machinists, tool-and-die makers, and CNC setup technicians install this collet as part of workholding setups requiring repeatable, accurate part positioning.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for round-stock workholding in both manual and CNC lathe applications. It is commonly used in job shops and production facilities where 5C collet systems are the standard workholding method. The 26.50mm bore accommodates round bar stock or turned parts of that diameter. Its steel construction handles the clamping forces and wear cycles typical of repetitive production runs without deforming the collet nose or bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e26.50mm round bore accommodates standard round stock of that diameter\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.015mm ensures tight concentricity for precision turning and grinding\u003c\/li\u003e\n  \u003cli\u003eSteel construction resists deformation under repeated clamping cycles\u003c\/li\u003e\n  \u003cli\u003eInternal thread: 1.041 inches-24; external thread: 1.242 inches-20, standard 5C dimensions\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.5 pounds, minimizing spindle load\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard addition for 5C collet-compatible lathes, collet chucks, indexers, and spin fixtures that accept the standard 5C collet form factor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA qualified machinist or tooling technician should install and seat 5C collets. Power down and lock out the spindle drive before inserting or removing collets from the chuck or closer. Inspect the collet bore and the spindle nose for burrs or debris before installation, as contamination will directly increase runout. Use a collet closer or drawbar tightened to the machine manufacturer's specification — do not overtighten, as this can collapse the collet slots and damage the bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Type\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 26.50mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.015mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: 1.041 inches-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 1.242 inches-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: 1230-4250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693786562866,"sku":"1230-4250","price":40.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ee051805af4a979bdd2f5d6de3cbe38.jpg?v=1788317333","url":"https:\/\/voomisupply.com\/products\/value-collection-1230-4250-5c-round-collet-26-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
