It mates with adjustable torque wrenches to allow controlled, repeatable tightening of ER20 collet nuts on CNC machining centers, milling machines, and similar toolholding setups. At 0.08 pounds, the wrench is compact and easy to handle at the spindle. Licensed machinists and toolroom technicians rely on this type of wrench to achieve proper collet seating without over-torquing the nut, which can damage the collet taper or reduce tool runout performance.\u003c\/p\u003e\u003cp\u003eThis wrench is intended for use in production machining and toolroom environments where ER20 collet chucks are in regular rotation. It is paired with an adjustable torque wrench to meet specific torque requirements for ER20 nut engagement. The hex drive interface provides a positive, slip-resistant connection during tightening. Typical applications include setup of ER20 toolholders on vertical machining centers, drill-tap centers, and manual milling machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHex wrench type for positive engagement with ER20 collet nuts\u003c\/li\u003e\n\u003cli\u003eDesigned for use with adjustable torque wrenches for repeatable torque application\u003c\/li\u003e\n\u003cli\u003eCompatible with ER20 collet series toolholding systems\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.08 pounds for easy handling during machine setup\u003c\/li\u003e\n\u003cli\u003eCompact form factor suits confined spindle access areas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ER20 collet chuck systems and adjustable torque wrenches as specified by the toolholder manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis wrench is installed by machinists and toolroom technicians during cutting tool setup. Before changing or seating collets, confirm the machine spindle is locked and the machine is in a safe, powered-down state per shop lockout\/tagout procedures. Use only with a compatible adjustable torque wrench to avoid over-tightening, which can deform the collet nut or reduce tool concentricity. Follow the toolholder manufacturer's specified torque value for the ER20 nut size in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWrench Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Adjustable Torque Wrenches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: TECHNIKS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 04602-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":52106601333042,"sku":"04602-20","price":73.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/33a11bafa10831019f5c110c44599803_d3831c4a-62df-4ac9-a8ab-a3fccf831dd7.jpg?v=1790073630","url":"https:\/\/voomisupply.com\/products\/techniks-04602-20-er20-collet-chuck-hex-wrench","provider":"Voomi Supply","version":"1.0","type":"link"}
