Each block features a 90-degree V-angle and accepts round stock from 1\/8 inch minimum up to 0.575 inch maximum capacity. Overall dimensions are 1-3\/8 inches long by 1-3\/8 inches wide by 1-3\/16 inches tall. The set holds V parallelism to 0.0002 inch and squareness to 0.0002 inch, making it suitable for close-tolerance work on the surface plate or machine table. A clamp and wooden storage case are included.\u003c\/p\u003e\n\u003cp\u003eThis V-block set is used in machine shops, tool rooms, and metrology labs for holding cylindrical workpieces during scribing, drilling, grinding, and inspection. The matched pair allows a shaft or pin to be supported at two points simultaneously, ensuring accurate alignment. Typical users include machinists, tool-and-die makers, and quality control technicians who need repeatable, low-runout workholding for cylindrical parts up to 0.575 inch in diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHardened steel construction for wear resistance and long service life\u003c\/li\u003e\n  \u003cli\u003e90-degree V-angle accommodates a wide range of cylindrical workpiece diameters\u003c\/li\u003e\n  \u003cli\u003eMaximum capacity of 0.575 inch; minimum capacity of 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003eV parallelism held to 0.0002 inch for precise, repeatable positioning\u003c\/li\u003e\n  \u003cli\u003eSquareness tolerance of 0.0002 inch supports accurate layout and inspection work\u003c\/li\u003e\n  \u003cli\u003eIncludes matching clamp and wooden case for organized storage and protection\u003c\/li\u003e\n  \u003cli\u003eSold as a 2-block matched set for dual-point workpiece support\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose matched V-block set suitable for use on standard surface plates and machine tables where cylindrical workpieces between 1\/8 inch and 0.575 inch diameter require precise support and alignment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlace both blocks on a clean, flat surface plate or machine table and verify seating before clamping a workpiece. Secure the workpiece using the included clamp to prevent movement during layout or machining operations. Inspect block faces and the V-groove for burrs or debris before use, as contamination will affect precision.
