Each plate measures 4.25 inches in length and 0.25 inches thick, covering an angular range of 30 to 90 degrees with an accuracy of 10 minutes of arc. The set includes two angle plates that allow machinists and toolmakers to establish consistent, repeatable angular reference planes on surface plates, milling fixtures, or inspection tables. The steel construction provides durability and resistance to wear under regular shop use.\u003c\/p\u003e\n\u003cp\u003eThis angle block set is suited for use in machine shops, toolrooms, and quality control environments where precise angular setups are required. Typical applications include setting workpiece angles on milling machines, establishing reference angles for layout work, and verifying part geometry during inspection. The two included plates can be combined or used independently to achieve a variety of angular positions within the 30 to 90 degree range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAngular range of 30 to 90 degrees covers common machining and layout angles\u003c\/li\u003e\n  \u003cli\u003e10 minutes of arc accuracy for precise angular reference work\u003c\/li\u003e\n  \u003cli\u003e4.25 inch overall length provides a stable reference surface\u003c\/li\u003e\n  \u003cli\u003e0.25 inch plate thickness for rigid, stable positioning\u003c\/li\u003e\n  \u003cli\u003eSteel construction for shop durability and long service life\u003c\/li\u003e\n  \u003cli\u003eSet of 2 angle plates included for versatile setup configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose angle block set for use with standard surface plates, sine bars, milling fixtures, and inspection equipment in machining and toolroom applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAngle blocks are typically used by machinists and quality technicians on clean, flat reference surfaces such as granite or cast iron surface plates. Ensure all mating surfaces are free of burrs, chips, and debris before use to maintain angular accuracy. Secure the workpiece or blocks with appropriate clamps or magnetic fixtures as required by the setup. Handle steel angle blocks carefully to avoid nicks or corrosion that can affect accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 10 minutes of arc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 13-184-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720551465266,"sku":"13-184-7","price":34.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39ae4003be3c6d4072ac9a4fbf956e24.jpg?v=1788565975","url":"https:\/\/voomisupply.com\/products\/spi-13-184-7-angle-block-set-30-90-degree-2-piece-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
