Each block features a 90-degree V angle and accepts round stock from 1-9\/16 inches minimum to 2-3\/8 inches maximum capacity. Overall dimensions are 4-3\/4 inches in length, 1-3\/8 inches in width, and 4-3\/4 inches in height. V parallelism is held to 0.0012 inches and squareness per 1 inch is 0.0012 inches, making these blocks suitable for precise cylindrical part inspection and machining setups. These are sold as a matched pair.\u003c\/p\u003e\u003cp\u003eThese V-blocks are used in machine shops, tool rooms, and quality inspection environments. Typical applications include supporting shafts, pins, and round bar stock during grinding, milling, layout, or inspection operations. The cast iron construction provides stable, vibration-damping support on surface plates or magnetic chucks. Machinists, tool and die makers, and quality control technicians working with cylindrical workpieces up to 2-3\/8 inches in diameter will find these blocks appropriate for their setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree V angle for secure cylindrical workpiece support\u003c\/li\u003e\n\u003cli\u003eMaximum V capacity of 2-3\/8 inches; minimum capacity of 1-9\/16 inches\u003c\/li\u003e\n\u003cli\u003eV parallelism of 0.0012 inches for precise alignment\u003c\/li\u003e\n\u003cli\u003eSquareness of 0.0012 inches per 1 inch for accurate layout and inspection\u003c\/li\u003e\n\u003cli\u003eCast iron construction for rigidity and vibration damping\u003c\/li\u003e\n\u003cli\u003eSold as a matched pair for paired-support setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 90-degree V-block pair for use with cylindrical workpieces in general machining, inspection, and layout applications requiring a V capacity range of 1-9\/16 inches to 2-3\/8 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eV-blocks are typically set up by machinists or quality technicians on a surface plate or machine table. Ensure the mounting surface is clean and free of chips or burrs before placing the blocks. When used for inspection, verify the surface plate is level and that both blocks of the matched pair are seated fully before indicating or measuring. These blocks are non-magnetic and are not intended for use directly on magnetic chucks without mechanical securing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eV Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum V Capacity\u003c\/strong\u003e: 1-9\/16 inches (39.69 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum V Capacity\u003c\/strong\u003e: 2-3\/8 inches (60.33 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-3\/4 inches (120.65 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1-3\/8 inches (34.93 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 4-3\/4 inches (120.65 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eV Parallelism\u003c\/strong\u003e: 0.0012 inches (30 micrometers)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness Per 1 Inch\u003c\/strong\u003e: 0.0012 inches (30 micrometers)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Matched Pair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10 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: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 91-295-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51693742850354,"sku":"91-295-6","price":138.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f3e38a74f060be4e0e74cea77278264.jpg?v=1788316815","url":"https:\/\/voomisupply.com\/products\/spi-91-295-6-v-block-2-3-8-in-90-degree-matched-pair","provider":"Voomi Supply","version":"1.0","type":"link"}
