The vise features a 3-inch jaw width and a 1-1\/4-inch jaw height, with a jaw opening capacity of 3-3\/4 inches. It holds workpieces square to within 0.0002 inches and parallel to within 0.0002 inches, making it suitable for high-tolerance surface grinding applications. Weighing 17.8 pounds, this is a solid-duty toolroom vise built for stable, repeatable setups on surface grinders and milling machines. Machinists and toolroom technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis sine vise is intended for use in toolroom and production grinding environments where compound or single-angle setups are needed. The 3-inch jaw width accommodates a wide range of workpiece sizes common in precision machining. Overall dimensions of 7-1\/2 inches in length, 3 inches in width, and 3-5\/8 inches in height keep the profile manageable on standard surface grinder tables. It is suited for both horizontal and vertical surface grinder applications where maintaining tight angular tolerances is critical to part quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch jaw width and 3-3\/4-inch jaw opening capacity for versatile workpiece clamping\u003c\/li\u003e\n  \u003cli\u003eSquareness within 0.0002 inches for high-precision angular setups\u003c\/li\u003e\n  \u003cli\u003eParallelism within 0.0002 inches to maintain consistent part positioning\u003c\/li\u003e\n  \u003cli\u003eAll-steel construction for durability and rigidity under grinding loads\u003c\/li\u003e\n  \u003cli\u003eCompact overall footprint: 7-1\/2 inches long, 3 inches wide, 3-5\/8 inches tall\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use sine vise compatible with standard surface grinder tables and milling machine setups requiring precision angular workholding.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and setup should be performed by a qualified machinist or toolroom technician familiar with precision workholding equipment. Demagnetize the grinder chuck and clean all mating surfaces before mounting the vise to prevent seating errors that can affect angular accuracy. Use gauge blocks or a precision sine bar in conjunction with this vise to establish the correct angle before tightening the workpiece. Do not exceed the jaw capacity of 3-3\/4 inches, as overloading the vise jaw can compromise clamping integrity and part tolerances.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Width\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Height\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Opening Capacity\u003c\/strong\u003e: 3-3\/4 inches (95.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.0002 inches (0.0051 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParallelism\u003c\/strong\u003e: 0.0002 inches (0.005 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 17.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 428-9530\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695913206066,"sku":"428-9530","price":168.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f21eed8650990fcdea6db31b5cb57474.jpg?v=1788339332","url":"https:\/\/voomisupply.com\/products\/value-collection-428-9530-sine-vise-3-in-jaw-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
