It fits into ER40-standard collet chucks and tool holders, providing consistent clamping force for milling, drilling, tapping, and turning operations. With an overall length of 1.811 inches and a clamping pressure rating of 1800, this collet delivers reliable tool retention for production and job-shop environments. Machinists and toolroom technicians install this collet as part of a precision workholding setup on CNC and manual machine tools.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for use in machining centers, lathes, milling machines, and multi-axis CNC equipment that accept ER40 collet chucks. It accommodates a 3\/4-inch (0.7500-inch) tool or workpiece shank and is a standard fitment in shops requiring repeatable runout performance across a range of cutting tool diameters. Typical applications include end mill holding, drill chucking, tap holding, and reamer retention in both production and prototype machining.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER40 collet series for compatibility with ER40 collet chucks and tool holders\u003c\/li\u003e\n  \u003cli\u003e0.75-inch (3\/4-inch) collet bore diameter for standard shank tooling\u003c\/li\u003e\n  \u003cli\u003e1.811-inch overall length for compact tool projection\u003c\/li\u003e\n  \u003cli\u003e1800 clamping pressure rating for secure tool retention\u003c\/li\u003e\n  \u003cli\u003eSuitable for milling, drilling, tapping, and reaming operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for ER40 collet chucks and tool holder systems that accept the ER40 collet series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians using an ER40 collet nut and the appropriate collet chuck wrench. Always clean the collet taper and chuck bore before seating the collet to ensure accurate runout. Do not exceed the rated clamping torque for the collet nut, and inspect the collet for wear or damage before each use. Worn or damaged collets should be replaced before returning the tool holder to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 0.7500 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.811 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamping Pressure\u003c\/strong\u003e: 1800\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: PARLEC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ERS40-0750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52028003615026,"sku":"ERS40-0750","price":87.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f8cc66e0d699599d1ac58d1be0719ed.jpg?v=1790017466","url":"https:\/\/voomisupply.com\/products\/parlec-ers40-0750-er40-collet-0-75-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
