Built with a cast iron body, it features a plain back mount configuration and delivers consistent clamping performance across a range of workpiece diameters. The chuck runs at a maximum of 1,500 RPM and holds axial runout to 0.0012 inches and radial runout to 0.0020 inches. At 106 pounds, this is a heavy-duty unit intended for installation by experienced machinists or shop maintenance personnel working with mid-to-large-capacity manual lathes.\u003c\/p\u003e\n\u003cp\u003eThis chuck is suited for production and job-shop environments where reliable, repeatable workholding is required on manual turning equipment. The plain back mount style requires a matching adapter plate or lathe spindle nose to be fitted before installation, making it adaptable to a variety of lathe configurations. Reversible jaws extend workholding flexibility, allowing the chuck to grip both small-diameter and large-diameter stock within its capacity range. Typical applications include turning, facing, and boring operations on cylindrical workpieces in metalworking environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSelf-centering 3-jaw design for fast, repeatable workpiece location\u003c\/li\u003e\n  \u003cli\u003eReversible jaws accommodate a wide range of workpiece diameters from 13\/64 inches minimum to 12-13\/32 inches maximum jaw capacity\u003c\/li\u003e\n  \u003cli\u003eAxial runout of 0.0012 inches and radial runout of 0.0020 inches for precision turning\u003c\/li\u003e\n  \u003cli\u003eCast iron body construction for rigidity and durability under continuous shop use\u003c\/li\u003e\n  \u003cli\u003ePlain back mount for compatibility with a variety of lathe adapter plates and spindle configurations\u003c\/li\u003e\n  \u003cli\u003eMaximum spindle speed of 1,500 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade chuck for manual lathes equipped with a plain back spindle nose adapter.

Always disengage power and bring the spindle to a complete stop before mounting or removing a chuck. Due to the weight of 106 pounds, mechanical lifting assistance or a minimum two-person lift is strongly recommended to safely position the chuck onto the spindle adapter. Verify runout with a dial indicator after mounting before returning the machine to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChuck Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Jaws\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChuck Type\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Plain Back\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1,500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Jaw Capacity\u003c\/strong\u003e: 13\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Jaw Capacity\u003c\/strong\u003e: 12-13\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Height\u003c\/strong\u003e: 2-23\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReversible Jaws\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough-Hole Diameter\u003c\/strong\u003e: 4.0551 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAxial Runout\u003c\/strong\u003e: 0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRadial Runout\u003c\/strong\u003e: 0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 16.93 inches L x 14.57 inches W x 9.45 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 106 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1-201-1200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727114895666,"sku":"1-201-1200","price":1487.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f450e6909ec2b53d2a11876c8daff39e.jpg?v=1788673584","url":"https:\/\/voomisupply.com\/products\/hertel-1-201-1200-lathe-chuck-3-jaw-12-in-plain-back","provider":"Voomi Supply","version":"1.0","type":"link"}
