It provides a controlled, repeatable clamping force when tightening ER40 collet nuts, helping ensure consistent tool runout and secure workholding during machining operations. This wrench head is used by machinists and CNC setup technicians who require precise collet preload without overtightening. Weighing 0.44 pounds, it is compact enough for routine use at the machine. It is a straightforward, purpose-built tool for ER40 collet chuck assemblies in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThe TWN-40ERNW is suited for shops running ER40 collet chucks on CNC machining centers, lathes, or manual mills. The torque wrench head format allows technicians to apply the manufacturer-specified clamping torque directly to the collet nut, reducing the risk of under- or over-tightening. It is a practical addition to any toolroom or CNC setup station where ER40 toolholders are in regular use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTorque wrench head style for controlled collet nut tightening\u003c\/li\u003e\n\u003cli\u003eSpecific to ER40 collet series for proper fit and engagement\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.44 pounds for easy handling at the spindle\u003c\/li\u003e\n\u003cli\u003eSupports consistent tool clamping force across repeated setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ER40 collet chuck assemblies and compatible ER40 collet nuts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis torque wrench head is installed and used by machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and all motion has ceased before handling collet chucks or tightening collet nuts. Follow the collet chuck manufacturer's specified torque value when using this wrench head. Do not use additional leverage or impact force on the wrench head, as this may damage the collet nut or chuck body.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWrench Type\u003c\/strong\u003e: Torque Wrench Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.44 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: TWN-40ERNW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":51971323560242,"sku":"TWN-40ERNW","price":115.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c6e6f37f107cf79f2f1983a629dff572.jpg?v=1789955554","url":"https:\/\/voomisupply.com\/products\/parlec-twn-40ernw-er40-collet-chuck-torque-wrench-head","provider":"Voomi Supply","version":"1.0","type":"link"}
