Fowler 52-475-015-1 2-3/4 in Cast Iron V-Block Set w/ Clamps

The Fowler 52-475-015-1 is a matched pair of hardened and ground cast iron V-blocks with a 2-3/4 in (70 mm) overall length, supplied with two threaded clamping screws for securing cylindrical workpieces during layout, inspection, and light machining operations. Each block features a 90° V-groove on the top face and a corresponding 90° V-groove on the bottom face, plus relief slots at the groove root to accommodate a full range of cylindrical diameters without the workpiece bottoming out; the stepped base profile visible in the photos provides stable, two-point contact on a surface plate or machine table. Both blocks are serialized "144" (visible in photos), confirming they are a factory-matched pair ground to the same reference plane to ensure co-axial alignment of round stock. This item is new — other (original box present but shows shelf/storage wear); the blocks themselves appear unused with no visible machining marks or wear on the V-faces. Typical applications include CMM setups, sine-bar work, surface-grinding setups, and cylindrical part inspection on a granite or cast iron surface plate.
