Constructed from high-carbon steel, it delivers tight parallelism of 0.005 mm and squareness of 0.0051 mm, making it suitable for grinding, milling, and inspection setups where repeatability matters. The jaws measure 2-7\/8 inches wide and 1-3\/8 inches tall, with a maximum opening capacity of 4 inches. Overall dimensions are 7.5 inches long by 2.938 inches wide by 2-5\/8 inches high. At 8.9 pounds, it is solid enough for secure clamping without excessive bench mass. Machinists, toolmakers, and surface grinder operators are the primary users.\u003c\/p\u003e\u003cp\u003eThis vise is designed for precision workholding applications on surface grinders, milling machines, and inspection tables in both production and toolroom settings. The flat jaw profile suits square and rectangular workpieces that require accurate, repeatable positioning. It is appropriate for both light-duty production work and single-piece toolmaking operations where close tolerances are required at the setup stage.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFlat jaw profile for accurate seating of square and rectangular stock\u003c\/li\u003e\n\u003cli\u003eParallelism of 0.005 mm for repeatable, close-tolerance setups\u003c\/li\u003e\n\u003cli\u003eSquareness of 0.0051 mm to maintain perpendicular workpiece alignment\u003c\/li\u003e\n\u003cli\u003eHigh-carbon steel construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e2-7\/8 inch jaw width with 4 inch maximum opening capacity\u003c\/li\u003e\n\u003cli\u003eCompact form factor at 8.9 pounds for bench and machine table use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use toolmakers vise suitable for standard surface grinder tables, milling machine tables, and inspection fixtures that accept a vise of this jaw width and overall footprint.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a machinist or toolmaker. Before mounting, verify that the machine table T-slots or mounting surface are clean and free of burrs that could affect the vise seating and introduce squareness error. Secure the vise using appropriate T-bolts or toe clamps rated for the machine table. Always indicate the vise jaw face with a test indicator after mounting to confirm alignment before beginning any cutting or grinding operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eJaw Width\u003c\/strong\u003e: 2-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJaw Opening Capacity\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJaw Height\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJaw Shape\u003c\/strong\u003e: Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParallelism\u003c\/strong\u003e: 0.005 mm (0.0002 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.0051 mm (0.0002 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 2.938 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 2-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.9 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 428-9230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689269952818,"sku":"428-9230","price":172.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b5837a4cd9e3a119205d281892cceae.jpg?v=1788256593","url":"https:\/\/voomisupply.com\/products\/value-collection-428-9230-toolmakers-vise-2-7-8-in-jaw","provider":"Voomi Supply","version":"1.0","type":"link"}
