The expanding design grips workpieces from the inside, securing bores and tubular stock for turning, grinding, or inspection operations. The collet offers a concentricity of 0.0020 inches TIR, a head diameter of 3 inches, and a head length of 1 inch. It is installed and changed by machinists and toolroom technicians as part of standard 5C workholding setups.\u003c\/p\u003e\u003cp\u003eThis expanding collet is suited for machine shop environments handling both production and toolroom work. The grip range spans a minimum of 0.7500 inches to a maximum of 2.9375 inches, making it practical for a variety of bore sizes encountered in turning and cylindrical grinding applications. The internal thread size is 1.041 inches-24 and the external thread size is 1.242 inches-20, conforming to standard 5C collet geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExpanding collet design grips workpieces internally for turning, grinding, and inspection\u003c\/li\u003e\n\u003cli\u003eConcentricity of 0.0020 inches TIR for consistent, repeatable workholding accuracy\u003c\/li\u003e\n\u003cli\u003eGrip range from 0.7500 inches to 2.9375 inches covers a wide variety of bore diameters\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability in production and toolroom machining environments\u003c\/li\u003e\n\u003cli\u003eStandard 5C thread geometry: internal 1.041 inches-24, external 1.242 inches-20\u003c\/li\u003e\n\u003cli\u003eHead diameter of 3 inches and head length of 1 inch for compatibility with standard 5C fixtures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit collet for standard 5C collet chucks, collet closers, and indexing fixtures that accept 5C-style expanding collets.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and changeover should be performed by a qualified machinist with the spindle fully stopped and all machine power off before handling collet components. Threads should be inspected for cleanliness and lightly lubricated with an appropriate thread lubricant before seating the collet. Do not exceed the collet grip range, as over-stressing the collet body can cause workholding failure or damage to the spindle nose. Follow the machine manufacturer guidelines for draw tube torque and collet closure procedure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Type\u003c\/strong\u003e: Expanding\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConcentricity (TIR)\u003c\/strong\u003e: 0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: 1.041 in-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 1.242 in-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Grip\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Grip\u003c\/strong\u003e: 2.9375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 230-4437\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710986191154,"sku":"230-4437","price":187.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd7fa05bfdc69ffe441c21f174c235a4.jpg?v=1788473186","url":"https:\/\/voomisupply.com\/products\/value-collection-230-4437-5c-expanding-collet-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
